  • vocabulary package in wrong namespace

    SPARQLConstants.java uses the wrong namespace for the vocabulary package. Using the latest (20051007) CVS of openrdf, the correct lines should read: import org.openrdf.model.vocabulary.RDF; import org.openrdf.model.vocabulary.XMLSchema; NOT: import org.openrdf.vocabulary.RDF; import org.openrdf.vocabulary.XMLSchema; Please build the SPARQL Engine from the latest CVS of Openrdf2...

  • Followup: RE: Status Update

    I forgot about section 10.1. The reason I brought it up is that common.Value requires implementations to code compareTo, but the documents don't suggest the comparison algorithm. Anyway, you need to provide abstract and concrete factories for creating the classes in the common package. Having adapters bind to your common.impl implementations is too strongly coupled! Jena's API does this...

  • Followup: RE: Status Update

    What does it mean for the values ot be compared? Like one URI being greater or less than another one? Or a URI being greater or less than a literal. That part confuses me. Also, note that Literals can have either a "xml:lang" tag, a datatype tag, but not both. (I'm using "tag" as meaing "metadata" and not the xml/sgml definition. Also, the xml:lang tag is...

  • JUnit should not be a dependancy

    JUnit is a testing framework and should only be used for test cases and not point-release code. However, several java files without "test" in their name require JUnit as a dependancy. The following files seem to run testcases, yet they are not in the "test" directory and they break conventions by not having "test" in their name: /jena2/src/jena/owlsyntax.java...

  • Howto port Saxon Extensions to Saxon.NET?

    Is there a way to port Saxon extension functions written in Java to Saxon.NET? What's the general pattern?.

  • Followup: RE: Starting point for SGML conversion

    Note that SGML has its own (complicated) transform language called DSSSL, which may be more suitable to your situation.

  • Converting a Java Object to an Item

    One of my extension functions uses a custom implementation of SequenceIterator as an adapter wrapped around another program's iterator. Since SequenceIterator iterates over Item objects, I have to convert a Java Object to an Item in Java (i.e. I don't think I can use Saxon to do it for me - the class has to explicitly convert it). However, there doesn't seem to be an easy way to do this...

  • Implementing SequenceIterator is EASY!

    The documentation doesn't indicate how **easy** it is to implement and use the SequenceIterator interface! It took me a few days before I realized it. The documentation should make this clearer and provide an example.
