Hi, Apache Jena uses a feature of Xerces 2 for validating strings that claim to be of XSD schema types, by using the org.apache.xerces.impl.dv.SchemaDVFactory and friends.
See for example: https://github.com/stain/jena/blob/JENA-878-explicit-impl-imports/jena-core/src/main/java/com/hp/hpl/jena/datatypes/xsd/XSDDatatype.java#L286 I believe this is very useful outside XML validation, as XSD datatypes are also used in non-XML formats for RDF, like Turtle and JSON-LD. The Xerces2-j javadocs however, warn: https://xerces.apache.org/xerces2-j/javadocs/xerces2/org/apache/xerces/impl/dv/SchemaDVFactory.html > INTERNAL: > Usage of this class is not supported. It may be altered or removed at any > time. and of course it is under the .impl package, which made OSGi throw warnings (and me raising the bug https://issues.apache.org/jira/browse/JENA-878 ) Is there a non-impl way in Xerces2-j to do this datatype validation without having to construct a temporary XML document and temporary schema? Should we really be worried about the org.apache.xerces.impl.dv package changing? It seems quite stable and good.. :) Would it be possible to suggest it being "upgraded" to non-impl (which ironically WOULD break existing calls :-/ ) or at least not to have that warning in the doc..? -- Stian Soiland-Reyes Apache Taverna (incubating) http://orcid.org/0000-0001-9842-9718 --------------------------------------------------------------------- To unsubscribe, e-mail: j-users-unsubscr...@xerces.apache.org For additional commands, e-mail: j-users-h...@xerces.apache.org
