Abstract

This document describes the Theological Markup Language (ThML), an XML markup language for theological texts. ThML was developed for use in the Christian Classics Ethereal Library (CCEL), but it is hoped that the language will serve as a royalty-free format for theological texts in other applications. Key design goals are that the language should be (1) rich enough to represent information needed for digital libraries and for theological study involving multiple, related texts, including cross-reference, synchronization, indexing, and scripture references, (2) based on XML and usable with World Wide Web tools, (3) automatically convertible to other common formats, and (4) easy to learn and use. ThML is defined as an XML DTD that extends the Voyager DTD for HTML.

Introduction

The study of theology involves uses of texts that are infrequent in other areas of study. Theological books usually make many references to the Bible, including quotations, commentary, explanations, and citations; special processing for scripture references can aid study. Theological study also often involves texts available in multiple variations or translations, sometimes in Greek or Hebrew, which may have to be synchronized and displayed in parallel columns. It may involve hymns and multiple media. It involves the use of cross-reference systems such as Strongs numbers, various sorts of indexes, and the synchronization of multiple texts in various ways, as for example layers of commentary on a text. Theological study often makes use of several texts related by subject or scripture reference, and tools that support library-wide searching by subject, scripture reference, name, or date would also be desirable. It should be possible for students to relate, combine, or comment on parts of texts in their own document, without altering the originals. A markup language for theological texts should support these applications.

For digital libraries, bibliographic information similar to that stored in a library card catalog should also be represented in the text. This information can be loaded into a software system similar to a library's Public Access Catalog (PAC) to provide an interface for locating books, though unlike a traditional library, searches can also be based on the contents of books. This information should be stored in a standard format so that it can be exported to other PACs and search engines, and searches can look through Internet-based digital libraries and PACs as well as documents on the local computer.

Multiple formats for electronic resources are a reality in today's computing environment. Theological study would also benefit from a markup language that is formally defined, with software for converting to and from other formats. And the language should be royalty free, so that texts can be prepared and distributed by small publishers, scholars, students, and other interested parties as well as large publishers. Ideally, no special purpose software for theological study should be required. This would be possible if all the desired applications could be supported by a web browser, for example. As a result, users would not be "locked in" to a particular proprietary software system. And the language should integrate with the World Wide Web, so that public domain texts can be downloaded from on-line libraries such as the CCEL. It should not be obvious to the user whether a text is on a CD-ROM, the local hard drive, or elsewhere on the Internet, except perhaps by access time.

Existing markup languages do not meet all of these needs. Word processor formats don't represent semantic information about a text—an area in which HTML is also weak. A lack of semantic information makes searching, indexing, and converting to other formats and using for other purposes more difficult. The Text Encoding Initiative (TEI)[1] application of SGML is semantically rich for literary analysis but not easy to learn or tuned for theological study. It doesn't offer special handling of scripture references or Strongs-like reference systems, for example. Also, the language is very large and the overhead required to learn and process the language is high. Commercial formats, including STEP[2] and the Logos Library System (LLS)[3], are not designed for integration with the Internet, and preparing texts for these systems requires expensive software, beyond the means of most individuals. Publication in one of these formats may also be controlled by the company or consortium in question. As a result, few public-domain or on-line texts are available in these formats.

This paper describes the Theological Markup Language, or ThML, which is a markup language for theological texts designed for use in the Christian Classics Ethereal Library (CCEL), a library of classic Christian texts on the Internet.[4] ThML is designed to meet the requirements outlined above. It borrows some elements from TEI, and it is designed to have all of the capabilities of STEP (version 0.9). ThML is an XML application, so ThML documents can be used directly with next-generation web browsers. These are programmable, so stylesheets and scripting languages will be able to add functionality such as that described above as well as format for display or printing on various devices. It will also be possible to convert ThML documents to other formats such as HTML webs, plain text files, PDF[5], RTF, and others.[6] ThML documents can be prepared with an XML editor, a plain text editor, or in Microsoft Word using a template and converting to ThML automatically. ThML resources are indexed on the ThML web page, http://www.ccel.org/ThML/.

After a couple of years’ experience with a digital library and thought about the information that needs to be represented in theological texts, the first version of ThML was designed in the summer of 1998, and it has been undergoing scrutiny and improvement since then. This paper describes version 1.0 of the language. Preliminary tools exist for converting Microsoft Word documents to ThML and for converting ThML documents to HTML webs. One open source software project (OpenBible) for Unix is using ThML and a couple of other groups are considering its use. There is a mailing list for those interested in defining and using the language. Several ThML documents exist and have been validated, and others are underway, including Schaff's History of the Christian Church and Calvin's Commentaries.

 

Designing a Theological Markup Language

A language for theological study must handle the markup of text into headings, paragraphs, block quotes, emphasized text, and other basic structural elements that are common to all books and can be represented in a markup language such as HTML. Markup needs for theological study that go beyond these basics include the special handling of scripture references, numbering and synchronization schemes such as Strongs numbers, handling multiple versions or translations of the same text, footnotes, index entries, lexicons, and representing page breaks in the original text.

For the use of digital libraries, bibliographic data about the text should be represented. Markup of subject index entries, scripture references and commentary, names, citations, and dates can be used to build library-wide indexes of those items and assist searching. The original pagination of the document should be represented for bibliographic references. Also, it should be possible to specify a "chunking" of the document for delivery over a low-bandwidth connections such as modems.

Since the primary means of delivering digital libraries such as the CCEL are the world wide web and CD-ROM, the language should use web-based technology, including XML and Unicode, and be usable with web browsers. Therefore, the design goals for ThML are these:

 

·         It should be usable with the world wide web and web-tool-based delivery on CD-ROM

·         It should represent information useful for theological study of multiple, related texts, including cross-reference, synchronization, indexing, and handling scripture references.

·         It should be rich enough to represent all information needed for conversion to other formats commonly used for electronic publication of books

·         It be rich enough to support high quality printing

·         Subject to these constraints, it should be as easy as possible to learn and use.

 

Document repurposing is much more easily achieved when purely semantic markup is used and description of appearance is restricted to stylesheets. This approach gives several benefits: it makes documents more flexible, allowing different stylesheets for the web, typesetting, large-type editions, etc. Mark-up editors are forced to think more about the semantics of the markup, rather than just trying to "make it look right" for a particular use. ThML makes possible purely semantic markup, with a level of semantic representation appropriate for digital libraries and theological study (though not for heavy literary analysis, as TEI). However, since the language is based on HTML, it is also possible to use it as presentational markup. The advantage of this approach is flexibility and familiarity; the disadvantage is that editors must be aware of the issues in order to produce good documents.

Theological Markup Language

Based on XML and HTML

Since Theological Markup Language is based on HTML and XML, it supports all of the markup of HTML, a rich linking language in XLink, and stylesheet support in CSS and XSL. HTML may be used for markup of emphasis, paragraphs, headings, lists, tables, block quotes, images and multimedia, scripts, etc. Links may make use of the extended pointer and link types associated with XML, and formatting will be specified in XSL. These facilities will be used wherever possible, to make the language easier to learn for those who already use HTML and easier to use with the World Wide Web.

Theological Markup Language is defined as a set of extensions to the Voyager Strict DTD of HTML. The DTD is presented in Appendix A and available from the ThML web page, http://www.ccel.org/ThML/dtd/ThML10.dtd. Since the Voyager DTD for HTML is an XML application, there are certain restrictions on the HTML that can be used. Most importantly, all element and attribute names must be lower case, all elements properly nested, and XML-style empty tags used (e.g. <hr/>).

Document Structure

ThML documents are contained in one global ThML element, and like HTML documents, they contain a head and a body section.

<ThML>

   <ThML.head> … </ThML.head>

   <ThML.body> … </ThML.body>

</ThML>

The ThML.body element contains all of the contents of the print edition of the book on which the text is based. The ThML.head element contains bibliographic and meta information about the text, both the electronic publication and the print edition upon which it is based, if any. The information in this section is not generally a part of the original book. It may include bibliographic data, keywords, information about the program used to generate the text, etc.

Divisions of the Text

Structural divisions in the body of the text are marked with <divn> tags as in this example:

<div1 type="Book" title="Admonitions on Things Internal" n="2">

<div2 type="Chapter" n="1" title="Of the Inward Life">

<div3 type="Section" n="I">

</div3> </div2> </div1>

<div1> is used for top level parts of a text, including the title page, preface, table of contents, chapters, index, etc. Additional levels are used for lesser structural divisions of the document. These structural divisions show the structure of the original text, and they are also used to prepare a table of contents and allow splitting of a text info files and access to a text by section. The optional title attribute is used in constructing a table of contents and may be used for running heads or other identification purposes. The optional type and n attributes may be used to specify the type and number of the division. If they are present, they will also be used to identify the section in the table of contents.

In programs that process ThML files for the CCEL, the <divn> elements are used to generate a table of contents and to split a book into multiple files.  By default, a new file will be started with each new <divn> element, unless the resulting file would be too small.  This "minimum desired file size" can be set with the filebreak="nnn" attribute.  Thus, filebreak="0" causes a break for each div and filebreak="10000000" prevents splitting the document at that point (at least for documents of less than 10000000 bytes length).

HTML <p> elements are used for normal paragraphs. They (and all other body elements) may be formatted with class attributes and stylesheets, as they would in HTML. <h1> through <h6> elements may be used for headings of varying levels of importance. Also, ThML adds an <argument> element, which may be used for a chapter or section subhead or topic of discussion.

Page Breaks

It is often useful to know the page breaks from the print edition of a book. They may be used as targets for subject index entries identified by page number or to display a text with the pagination of the print edition. Page breaks are marked by the insertion of <pb /> tags, with the n attribute giving the page number of the upcoming page (<pb n="37" /> or <pb n="xii"/>). These elements should appear at the start of the identified page. Many electronic texts will also have images of pages available on line. The pb element will also take an href attribute specifying a URI for an image of the page (<pb n="37" href="gif/0021a.gif" />).

Scripture References

In theological texts, scripture passages may be cited, quoted, or explained. Citations refer to a passage, and they are represented in ThML with the <scripRef> element. That element specifies that the enclosed text is a scripture reference. A ThML processor might link the text to the passage and include it in a scripture reference index, for example. Quoted scripture is marked with the <scripture> element. Commentary on scripture, sermons or hymns based on scripture, and other material that would be useful to someone studying a passage is marked with the <scripCom/> element. In addition, a <scripContext> element is available to set the default version, book, or chapter for succeeding references. All four elements may optionally have the attributes version, passage, and parsed, containing the version of the references, the passage referred to, and a machine-friendly parsed version of the passage.

A reference such as "Romans viii. 27,28; x. 8-13" for the NIV could be marked in a number of ways. A full specification would appear as

<scripRef version="NIV" passage="Rom. viii. 27,28; x. 8-13" parsed="NIV|Romans|8|27|8|28;NIV|Romans|10|8|10|13">Romans viii. 27,28; x. 8-13</scripRef>

or perhaps

<scripRef version="NIV" passage="Rom. viii. 27,28" parsed="NIV|Romans|8|27|8|28">Romans viii. 27,28</scripRef>; <scripRef version="NIV" passage="x. 8-13" parsed="NIV|Romans|10|8|10|13">x. 8-13</scripRef>

However, a number of shortcuts are possible. If a parsed attribute is not used, processing software can parse the passage and add it. The version can be inferred from the most recent <scripContext> element or left unspecified. The passage attribute can even be omitted when the enclosed text is an unambiguous scripture references. So, the above passage could have been marked as

<scripRef>Romans viii. 27,28; x. 8-13</scripRef>

 

The passage attribute is a list of scripture references separated by commas or semicolons. Each reference may consist of a book name (or abbreviation), a chapter, and a verse. The chapter and verse are separated by a semicolon or period. If two references are separated by a dash, all of the intermediary verses are included as well. In the case of books with only one chapter, a reference consists of a book name or abbreviation and a verse. Book names should be as they appear in the version in use or a unique prefix of at least two letters of the name. Abbreviations that are not prefixes may also be accepted by programs that process ThML documents.[7]

The parsed attribute consists of a number of references separated by semicolons. Each reference includes the version, book, from chapter, from verse, to chapter, and to verse separated by the vertical bar ('|') character. The version may be omitted. If the from chapter is zero, the whole book is identified. If the from verse is zero, the whole chapter is specified. If the to chapter and verse are zero, a single verse (from chapter:from verse) is specified.

Note that different translations of the Bible use different versification schemes. For example, Psalm 9 in the King James Version is split into two—Psalms 9 and 10—in the Septuagint. In order to interpret a reference, the versification scheme used must be known. Scripture references will be assumed to be compatible with the versification scheme used by the KJV, ASV, NASB, NIV, and TLB unless otherwise specified. However, specifying that the scripture version for a passage is the Septuagint, for example, implies that the references is based on the Septuagint scheme. References to the Apocrypha without a version specified are interpreted according to the scheme used in the NRSVA (New Revised Standard Version with Apocrypha).

Also, context is sometimes necessary in interpreting a reference. A passage may refer to Romans 8:28 at one point and later to verses 29 and 30 and chapter 10:8-13. It will be up to the editor to identify and mark scripture references, although software may be provided to identify possible scripture references and suggest an interpretation such as <scripRef passage="Rom. 8:29,30">verses 29 and 30</scripRef>. The <scripContext version="NIV" passage="Romans 8" /> element may be used to set the default version, book, or chapter for upcoming references to the parser.

Quotations of scripture are marked with the <scripture> element. A passage may be represented as in this example:

<scripture passage="Mark 7:16" version="NKJV">If anyone has ears to hear, let them hear!</scripture>

This markup may also be used for a translation or version of a book or a whole Bible, perhaps as in the example below. Scripture marked in this way could be automatically retrieved by book, chapter, and verse with an appropriate program.

<scripContext version="Calvin's Translation, in English" /> …

<scripContext passage="Romans 8" /> …

<scripture passage="28">We further know, that to those who love God all things co-operate for good, even to those who are called according to <I>his</I> purpose:</scripture>

<scripture passage="29">for those whom he has foreknown, he has also predetermined to be conformed to the image of his Son, that he might be the first born among many brethren;</scripture>

 

Explanation or commentary on a passage involves a semantic relationship between the explanation and the passage explained. This relationship should be represented in the text in order to be able to build an index of scripture commentary. For example, it would be useful to be able to see everything the early church fathers said or preached on a passage. Commentary or explanation of a passage will marked with a <scripCom/> element, as in this example:

<scripCom passage="Mark 7:16" />Mark 7:16. This admonition seems to apply to most everyone . . .

The <scripCom/> element also takes an optional type attribute. The type is used in the CCEL for classifying references into one of a number of fixed types, including Commentary, Treatises, Sermons, Hymns, Prayers, Drama, etc. These then appear in a classified list of references for the whole library.

Cross Referencing Schemes and Synchronization

Cross referencing is the specification and linking of related passages in separate texts. Cross referencing in theological texts takes many forms. They include simple links such as those that can be handled by an HTML anchor; numeric or symbolic indexing schemes such as dates, Strongs numbers, scripture references, or subject index entries; annotation such as footnotes and commentary; different translations of the same text, etc. In this section we will define markup for handling symbolic cross-referencing schemes other than those that can be handled as ordinary links, scripture references, or annotation.

Standardized symbolic cross reference schemes such as dates, keywords, or Strongs numbers aren't really links to other documents, because any two documents with compatible cross reference schemes can be linked together and no particular documents are specified. Therefore XLL links, element IDs, etc. don't capture the semantics of such information. We will define a new sync element to represent this information. For example, the element

<sync type="Strongs" value="G42" />

might be used to represent a Strongs number at a location in a text.

Software tools may be provided to use this information in a variety of ways. For example, a program would be able to find other passages on related topics or create an index using the Strongs numbering. Multiple different manuscripts of the same original text could be aligned this way, and displayed in parallel columns, with appropriate software.

The scheme name given in the type attribute are not pre-defined; applications may invent new synchronization types for specific purposes. For example, the Rule of Benedict is available in several different manuscripts in two different traditions. If a common synchronization scheme were defined and manuscripts marked up, any two or more could be selected and aligned as parallel columns on the screen, or alternate forms of a passage could be located.

Annotation

In a ThML document, footnotes, endnotes, etc. are all marked with the <note> tag, following the syntax used by TEI Lite[8] for the most part. The note element may take the following attributes: place, resp, target, targetEnd, and anchored. The place attribute specifies how it appears in the text (e.g. end, foot, inline, or margin). The target (and targetEnd) attributes refer to the start (and end) of the text being annotated, if the note does not occur in the text at its reference point. These attributes allow the notes to be gathered at the end of a chapter or file if desired. The resp attribute identifies the person responsible for the note—for example, the author, editor, or a person's initials. The anchored attribute make take the value yes (default) or no, specifying whether the note is anchored at an exact location; margin notes typically are not anchored.

The <note> element can also be used to store commentary, margin scrawls, and the like for a text in a separate file. In that case, the target and targetEnd attributes would be references to a point in another document.

Foreign Languages

The primary language for a document is specified in the header. Passages in other languages may be marked with the foreign tag and the lang attribute. For example, the Greek passage <foreign lang="el">logos</foreign> may be marked as shown. "lang" attribute values are as specified in ISO 639.[9] Some examples are Dutch: nl, English: en, French: fr, German: de, Greek: el, Hebrew: he, Latin: la, Spanish: es, Portuguese: pt, Russian: ru. Note that the lang attribute may be used with most elements.

If the language uses characters not available in the ISO-8859-1 (Latin-1) character set, they may be represented in Unicode, as in this Greek example (λογος) and this Hebrew example (הלהי), or using the Latin-1 character set and a suitable font, for example, <foreign lang="el" style="Font-family: SIL Galatia">logov</foreign>. The Greek and Hebrew fonts recommended for use with the CCEL are the freeware SIL Galatia and SIL Ezra fonts and related software from the Summer Institute of Linguistics[10], used here in a Greek example (logov) and a Hebrew example (hwhy). Foreign languages represented with special fonts may eventually be converted to Unicode programmatically.

Attributions, Citations, Dates, Names, and Unclear text

Attributions of authors of poetry, letters, etc. may be marked with the <attr> element. Also, names may be marked with the <name> element. A different representation of the name for the index may be specified with the title attribute: <name title="Ter Steegen, Gerhard">G. Ter Steegen</name>. (The title attribute may be used with any element; it is displayed in index entries and tables. In web-based presentation of a book, it may also be presented as a "tool-tip".) The <unclear> element may be used to mark words or passages that could not be transcribed with certainty or passages that a proofreader judges dubious.

Citations of other works such as books or treatises may be marked with the <citation> element. That element may also take an href attribute to specify a URI for the cited work, if available. The <date> element may be used to mark dates that occur in the text. A value attribute may be used to specify the date in ISO format, as in this example: <date value="1997.12.25">last Christmas</date>. These elements are used in the CCEL to aid searching and indexing: the insertIndex element (described in the next section) may be used to insert an index of attributions, works cited, dates, or personal names, and searches for names, attributions, dates, etc. can also be supported.

Verse

Theological books often contain verse—poetry, hymns, or versified presentation of material such as the Psalms. A stanza, verse, or other unit of verse is encoded in a <verse> element. Lines are marked with <l> elements. Lines that are formatted with varying levels of indentation may be formatted with the class attribute, as in the example below.

<verse>

<l class="t1">O God, a world of empty show,</l>

<l class="t2">Dark wilds of restless, fruitless quest</l2>

<l class="t1">Lie round me wheresoe'er I go: </l>

<l class="t3">Within, with Thee, is rest.</l3>

</verse><verse>

<l class="t1">And sated with the weary sum</l>

<l class="t2">Of all men think, and hear, and see, </l2>

<l class="t1">O more than mother's heart, I come, </l>

<l class="t3">A tired child to Thee. </l3>

</verse><verse>

<l class="t1">Sweet childhood of eternal life! </l>

<l class="t2">Whilst troubled days and years go by, </l2>

<l class="t3">Within Thine Arms I lie. </l3>

</verse><verse>

<l class="t1">Thine Arms, to whom I turn and cling</l>

<l class="t2">With thirsting soul that longs for Thee; </l2>

<l class="t1">As rain that makes the pastures sing, </l>

<l class="t3">Art Thou, my God, to me. </l3>

</verse>

<attr><name>G. Ter Steegen</name></attr>  

Hymns

ThML also has support for hymns and hymnals. The <hymn> element may contain elements <meter>, <author>, <tune>, <composer>, <incipit/>, and <music>, in any number and order, as well as other inline elements such as paragraphs, headings, <verse>, etc. The <author> and <composer> elements take authorID and composerID attributes, which may contain a standard identifier such as the CCEL personIDs, as well as the type attribute. The tune element contains the tune name; it may also have a tuneID attribute containing the CCEL tuneID for the tune.

The <meter> element contains the meter as represented in the hymnal. It may also take the standard attribute, giving the meter in a standardized form. The <incipit/> element may be used to represent the first line of the melody as it would be if transposed to C, using f and s for accidentals, e.g.

<incipit value="CEfGGGFAGFEf" />

Finally, the <music/> element gives a link to an electronic format for the music, perhaps a PDF page image or a midi file. The element takes the href attribute, giving the target, and the type attribute, giving the MIME type of the target. It may also take the inline attribute, with the value yes or no, and the actuate attribute, with the value auto or man. For images, specifying inline="yes" loads the image onto the page; otherwise it is loaded in a separate window. Specifying actuate="auto" makes the image appear automatically; otherwise it appears when a link is clicked. For audio files, specifying inline="yes" brings a player control onto the page. So, for example, to specify that a midi file be played automatically when a page is loaded, and that a player control be displayed, one could use

<music href="hymn.midi" type="application/midi" inline="yes" actuate="auto"/>

Index Entries and Indexes

A point in the text may be marked for insertion into an index using the <index> element. For example, one might mark a passage for inclusion in a subject index this way:

<index type="subject" subject1="Christian Life" subject2="Sanctification" title="Apotheosis"/>Apotheosis (or Deification) is an ancient theological word commonly used in Eastern theology to describe the process by which a Christian becomes more like God.

The title attribute is used as the identifier in the Table of Contents. The type attribute is used to identify the index that this reference is to be added to; values used for the CCEL include subject (the subject index for the book) and globalSubject (the library-wide subject index). Other values may be used for specialized indexes.

Up to four levels of subjects may be specified. The terms used for the subject1, subject2, subject3, and subject4 attributes may be chosen by the editor or selected from a fixed set, as determined by the application. The CCEL will use the Library of Congress classification scheme, but editors may also choose subject entries that seem appropriate; these will then be translated into LCCS subjects. An optional subjectID attributed may be used in place of the subject1subject4 attributes; it specifies a code for a set of subjects. For the CCEL, the subjectID value would be a Library of Congress call number, such as BV4138.

A document may have several user-selected types of index entries. An XML element (<insertIndex type="subject" />) is also provided to specify that a sorted, hierarchical index of all the "subject" (e.g.) index entries should be inserted at that point, with links to the appropriate locations in the text. Certain additional index types are also understood: <insertIndex type="name" /> inserts an index of all names marked with the <name> element; if the title attribute is present, it is used as the index entry. Similarly, indexes may be inserted for citations, dates, foreign words and phrases, images (<img>), names, scripture references (<scripRef>), and scripture commentary (<scripCom>).

Terms, Definitions, and Glossaries

Some documents contain one or more glossaries. Glossaries may be marked up with the <glossary> element and <term> and <def> elements. The glossary element may take an optional type attribute, to specify how the glossary may be used.

<glossary>

<term>Apotheosis</term>

<def>An ancient theological word used to describe the process by which a Christian becomes more like God</def>

</glossary>

Software tools may be provided for composing two documents (which may be the same), using the glossary in one and the text in another. Words of the text defined in the glossary could be footnoted, underlined and linked, or defined in a separate window.

Additions and Deletions

The <ThML.body> section of the electronic text should have all of the contents of the print edition. However, for display purposes, it may be desirable to add to or delete from the print edition. For example, it may be desirable to delete the original subject index and add one that is generated automatically. The <added> element is used to mark sections that have been added and do not appear in the print edition, and the <deleted> element is used to mark the sections from the print edition that should not appear when the book is presented, even though they remain in the XML for those who want to see exactly how the print edition looked. For example, a subject index might be marked this way:

<added>

<H1>Subject Index</H1>

<insertIndex type="subject" />

</added>

<deleted>

[original subject index here]

</deleted>

The added and deleted elements take the optional attributes resp, which identifies the person responsible for the changes; reason, identifying the reason for the change, and date, the time of the change.

Header Information

The head section of a ThML etext has the information about the text, information which does not necessarily appear in the text. It consists of a Dublin Core bibliographic record for the document and a few other elements that are useful for digital libraries. The <ThML.head> element has the most detailed (and least frequently used) markup; in practice it will normally be generated from a template. A sample template may be found in Appendix B. Note that a few items of information are duplicated between the ThML.head elements and the Dublin Core bibliographic record. This is the case because ThML requires these elements to be present in the header, but all elements in the Dublin Core are optional.

The head section may start with some HTML elements, such as <title> and <meta/>. There follow three sections that are unique to ThML: <generalInfo>, <electronicEdInfo> and <printSourceInfo>.

The <generalInfo> section contains information about the text that is not specific to the electronic edition or the print edition on which it is based. The section is optional, as are its four elements:

 

<generalInfo>

<description>      Textual description of book

<firstPublished>      Date first published in any edition

<pubHistory>      Any available information on the publication history

<comments>      Any other comments

</generalInfo>

 

The optional printSourceInfo section contains information specific to the print source from which the electronic text was derived, if there is one. The elements it may contain are these:

 

<printSourceInfo>

<published>       Publication information (required)

<copyLocation>      E.g. Buswell library, 231.4 b29h c.2.

<image type="…" href="…"/>      Electronic image of the book

</printSourceInfo>

 

The electronicEdInfo section contains information specific to the electronic edition, such as publication information, editorial practices and status, etc. It may contain the following elements (required elements are marked with *):

 

<electronicEdInfo>

<publisherID>      *Publisher code of electronic edition, as assigned by the CCEL, e.g. ccel

The Dublin Core (DC) element contains any combination of the 14 Dublin Core elements. All are optional and may be repeated in any order. The semantics are as described in the Dublin Core documentation[11], with a few additions. The elements are as follows:

 

<DC.Title>         <DC.Creator>         <DC.Subject>         <DC.Description>

<DC.Publisher>         <DC.Contributor>         <DC.Date>         <DC.Format>

<DC.Identifier>         <DC.Source>         <DC.Language>         <DC.Relation>

<DC.Coverage>         <DC.Rights>

These elements all have three optional attributes: lang, scheme, and sub. The lang attribute is the language in an ISO639-1 representation. The scheme attribute identifies the representational scheme. in The sub element represents subtypes, such as the Created subtype of the Date element. So, for example, the publication date might be represented as

<DC.Date sub="Created" scheme="ISO8601">1999-12-23</DC.Date>

Special usages for the CCEL include the following:

<DC.Creator>Thomas, &agrave; Kempis, 1380-1471</DC.Creator>

      - This is the unified form of the name

<DC.Creator scheme="CCEL">kempis</DC.Creator>

      - This is the CCEL personID for the person

<DC.Subject scheme="LCCN">BV4821.A1 1949</DC.Subject>

<DC.Subject scheme="LCSH">Meditations.</DC.Subject>

      - For the CCEL, the Library of Congress Call Number and Subject Heads should be included.

<DC.Subject scheme="CCEL">Classic; Recommended</DC.Subject>

Some special keywords (separated by semicolons) control the use of the document in the CCEL:

Biography – it is a biography of a person, who is identified as shown below

Classic – include on list of classics

Fiction – a work of fiction

Non-Fiction – [Default]

Recommended – include on list of recommended readings

Hymns – include on list of hymns and hymnology

Reference – include on list of reference items (e.g. dictionaries, encyclopedias, commentaries)

<DC.Subject scheme="target">anselm</DC.Creator>

      - The target of a biography is identified by the CCEL personID

<DC.Description> In preparing this edition of The Imitation of Christ, the aim was to achieve a simple, readable text which would ring true to those who are already lovers of this incomparable book and would attract others to it.</DC.Description>

      - The description should be a couple of sentences or a paragraph. In the CCEL, it will be used in indexes and links to the book.

 

<DC.Contributor sub="Transcriber" scheme="CCEL">whp</DC.Contributor>

      - info about the transcriber, typist, or person responsible for markup can be represented here

<DC.Identifier scheme="CCEL">http://www.ccel.org/ccel/kempis/sample/1.15.htm</DC.Identifier>

      - CCEL standard identifier, as described below

<DC.Identifier scheme="URL">http://www.ccel.org/ThML/sample/About.htm</DC.Identifier>

<DC.Source sub="ElectronicEdition">Project Gutenberg</DC.Source>

<DC.Source sub="PrintEdition">Milwaukee: Bruce Publishing Company, 1949, c1940.</DC.Source>

<DC.Language scheme="ISO639-1">en</DC.Language>

Handling Multiple Volumes

To handle multi-volume works such as a commentary or encyclopedia, each volume may be handled as a separate ThML document. An additional ThML document may then be prepared which combines all of the volumes into one larger unit. The document might look like this:

 

<ThML>

 <ThML.head>

    <!-- information about the whole series -->

  </ThML.head>

  <ThML.body>

    <!-- document for entire series, e.g. a series-wide table of contents-->

  </ThML.body>

  <!ENTITY volume1 SYSTEM "volume1.xml" />

  &volume1;

  <!ENTITY volume2 SYSTEM "volume2.xml" />

  &volume2;

  <!-- rest of volumes here -->

</ThML>

Alphabetical List of ThML Body Elements

The following list contains the elements that may be used for ThML markup in the body section of a text. Elements that occur in HTML may also be used, but they are not listed here. Elements concerning hymns are also not listed here; see the section on hymns above.

Table 1: ThML Body Elements

Using ThML in the CCEL

The way that ThML is used in the CCEL is in some cases more specific than the description above. For example, the <note> element merely identifies text as a note of some sort. The software used in the CCEL moves this text to the end of a section and links it with a footnote marker. Some of the special uses of ThML have been documented above; some others are given here.

·         authorID, bookID, and publisherID attributes are keys in the CCEL database, limited to 12 characters.

·         CCEL URIs are of the form [http://www.ccel.org/]ccel/authorID/bookID[_version].fmt where ".fmt" identifies the desired format, e.g. .htm, .txt, .xml, etc. The URL may also have |id1 or #id2 appended. In the former case, only the element whose ID is id1 is returned. The latter case works like an HTML hash. Both forms may be combined. Three special IDs are also available: _TOC, a machine-generated table of contents, _About, a machine-generated page of information about the document, and _Pnnn the specified page.

Conclusion

Theological study requires text with relatively rich markup. The Theological Markup Language has been designed to address these needs powerfully and without too much complexity. ThML was designed to be a rich enough representation to support powerful indexing and user interface features and to allow conversion into other popular formats without loss. It is also hopefully a language that can be learned without extraordinary effort. It is a fundamental element of the Christian Classics Ethereal Library system, and it will make the library far more functional and useful.


 

Appendix A: ThML DTD v. 1.0

 

 

The ThML DTD is based on the Voyager DTD for HTML. It uses the voyager DTD and four additional files: ThML.dtd, ebook.mod, bible.mod, and hymn.mod. The last three are modules that add support for general electronic books, scripture references, and hymns.

[2] The Standard Template for Electronic Publishing (STEP) format was developed by members of the Bible Software Industry Standards Group (BSISG, http://www.bsisg.com), including Parsons Technology.  It is a multi-vendor standard for Bible software.

[3] The format used by Logos, Inc. (and licensees) for Bible and theological book software.

[5] Portable Document Format, used by Adobe Acrobat software.

[6] Handheld computers may provide a better user interface than a desktop or laptop computer for reading books. Book-reading software and formats tuned for these devices will doubtless become common, if web browsers don't meet the need.

[7] The section marking scripture references draws from the STEP Programming Specification and the STEP Publishing Specification (available at http://www.bsisg.com).
