Information technology -- Text and office systems -- Using SGML Public Identifiers for Specifying Data Notations

Traitement de l'information -- Systèmes bureautiques -- Utilisation des identificateurs publics SGML pour la spécification des notations de données

Foreword

The Standard Generalized Markup Language (SGML), which is defined in ISO 8879, allows structured data to be interchanged among computer systems in a format that is independent of the applications creating or using the data. While the processing of text characters is fully defined in the standard, the processing of non-SGML data embedded within an SGML document is simply handled by passing the data to an appropriate processor.

Non-SGML data components are identified as being represented using a specific notation. Public identifiers identify notations in a system-independent manner; system identifiers do so in a system-dependent way . These identifiers may, for instance, identify documentation that defines the notation, the processor that was used to create the data, or a process that is intended to apply to the data.

When SGML documents containing non-SGML data are exchanged among computer systems it is necessary to build tables that link each notation with particular processes in the application. Where public identifiers are used these tables can be defined in an entity called a 'catalog' that links the public identifier with a notation processor. Where the notation declarations contain system identifiers, these must be changed individually if the receiving system does not contain the same notation processors as the originating system.

The process of building catalogs can be greatly simplified if the public identifiers used to identify notation processors are shared by applications. This technical report provides a starter set of both notation names and public identifiers which can be used to indicate the coding used for data that conforms to internationally agreed standards published by bodies such as ISO, IEC, ITU and SMPTE. While the notations names are purely advisory, the public identifiers are defined according to the rules for naming ISO standards defined in ISO 8879 and ISO/IEC 9070. These forms should be common to all applications that use formal public identifiers.

1. Scope

This Technical Report facilitates the interchange of data represented in internationally standardized notations ("data formats")" by providing a set of ISO/IEC 9070 public text object identifiers and ISO 8879 notation declarations that different applications can reference to identify the use of such data formats.

The public text object identifiers provided in this Technical Report have been based on the title assigned to the relevant standard in the the ISO catalogue and the catalogues of the International Telecommunications Union (ITU) and the Comité Consultatif Internationale de Téléphones et Télégraphes (CCITT).

Note 1: It has proved impossible to include de-facto standards in this version of this Technical Report due to the unwillingness of developers to agree to a common form of referencing. Such standards should be identified, wherever possible, by the ISBN of a published document that contains a formal definition of the data format. Where there is no formally published definition of a data format, the developer of the format should be asked to register an identifier with ISO, or define an ISO/IEC 9070 public text object identifier that would be the preferred method of referring to the data format.

3. Naming conventions

3.1 ISO/IEC 9070 names

ISO/IEC 9070 provides methods for identifying data formats by reference to:

Note 2: The above list is ordered according to the precision provided by the public identifier. A dated ISO reference is more specific than an undated ISBN reference. An ISO registered public identifier is more formally defined than an ISO/IEC TR 9573-9 identifier, but neither requires the specification of the data notation to be available to the general public, which ISO and ISBN numbers require (through copyright libraries, etc).

Because ISO/IEC 9070 restricts the length of object names to 100 characters (including spaces) it has proved necessary to shorten some of the titles used as names to identify international standards within ISO/IEC 9070 public identifiers.

3.2 SGML public identifiers

To encourage use of these names in document type definitions conforming to ISO 8879 and its associated standards, including the Hypermedia/Time-based Structuring Language which is defined in ISO/IEC 10744, an SGML notation declaration has also been prepared for each notation identified in this Technical Report. Each SGML notation declaration has the following components:

Note 3: The names assigned to each notation in the SGML notation declaration are only suggestions indicating commonly used short identifiers for these notations.

The full names of standards can normally be utilised in SGML notation declarations where, once SGML had reduced multiple spaces and line-endings to a single space, a literal length of 240 is the default.
