> Summary
> The programming-language, os, and name properties are literals, not URIs.  They should not be written as rdf:resources in the RDF output.
> The Problem
> While the resulting RDF will validate, what happens is that an RDF parser will interpret <programming-language rdf:resource="java" /> as a URI fragment.  (see the attached incorrect doap-language-bugreport.tgz:/target/site/doap_doap-language.rdf) 
> Since there is no explicit xml:base in the DoaP file generated by the plugin, the resulting URL is based on the default supplied by the RDF parser.  For example using the W3C RDF Validator yields: http://www.w3.org/RDF/Validator/run/java rather than simply "java"
> XML Base for RDF is specified at: see http://www.w3.org/TR/2003/PR-rdf-syntax-grammar-20031215/#section-Syntax-ID-xml-base
> Also note that the Apache Doap instructions correctly do not have rdf:resource for the programming language element: http://projects.apache.org/languages.html
> The Fix
> Instead of <programming-language rdf:resource="java" />, the plugin should generate <programming-language>java</programming-language>.
> Similar changes apply to the os and name properties.
> Validation
> I am attaching diffs that include changes to the unit tests.  Also, the RDF validator at http://www.w3.org/RDF/Validator/direct may be used to demonstrate that the progamming language, etc. elements are getting resolved to: http://www.w3.org/RDF/Validator/run/java rather than simply "java".  Simply "java" is what it should be.
