Schema Converters, Version 1.0
Date: Fri, 24 Sep 1999 06:34:24 +0200 From: Ronald Bourret <rbourret@ITO.TU-DARMSTADT.DE> To: XML-L@LISTSERV.HEANET.IE Subject: ANN: Schema Converters, Version 1.0
Version 1.0 of the Schema Converter package is now available at:
The Schema Converters are a set of Java packages you can use to: a) model a DTD as Java objects, and b) convert to and from these objects from DTDs and XML schema languages. Thus, it is possible to build arbitrary converters between different schema languages, as well as to and from DTDs.
The Bad News:
The only schema language currently supported is DDML.
The Good News:
The package includes the hardest converter -- from a DTD to the intermediate DTD objects -- which is most of an XML parser.
What This All Means:
If you need to convert from DTDs to any schema language other than DDML, you can use the package as a basis and write your own converter from the intermediate DTD objects to the schema language. This takes about half a day, assuming you know the schema language.
If you need to convert from a schema language other than DDML to a DTD, writing the converter takes about a day, assuming you support only the basic constructs. (It will take longer if, for example, you support such things as archetypes in the W3C's schema language or schema reuse in SOX or DCD.)
The Schema Converter package is completely free for use in both commercial and non-commercial settings and comes with complete documentation and source code.
