Hey,
I have just committed a bunch of really cool fixes to the REST stuff.
Both Entities and Entity descriptors are now output as RDF. Here's an
example RDF (/entity/org.qi4j.rest.TestEntity.rdf) for a type:
?xml version="1.0" encoding="UTF-8"?>
<rdf:RDF
xmlns:qi4j="http://www.qi4j.org/rdf/model/1.0/";
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#";>
<rdfs:Class rdf:about="urn:qi4j:org.qi4j.rest.TestEntity">
<rdfs:subClassOf rdf:resource="urn:qi4j:org.qi4j.entity.Lifecycle"/>
<rdfs:subClassOf rdf:resource="urn:qi4j:org.qi4j.entity.Entity"/>
<rdfs:subClassOf
rdf:resource="urn:qi4j:org.qi4j.entity.EntityComposite"/>
<rdfs:subClassOf rdf:resource="urn:qi4j:org.qi4j.entity.Identity"/>
<rdfs:subClassOf rdf:resource="urn:qi4j:java.io.Serializable"/>
<rdfs:subClassOf rdf:resource="urn:qi4j:org.qi4j.composite.Composite"/>
</rdfs:Class>
<rdf:Property rdf:about="urn:qi4j:property:org.qi4j.rest.TestEntity:name">
<rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#string"/>
</rdf:Property>
<rdf:Property rdf:about="urn:qi4j:property:org.qi4j.rest.TestEntity:age">

</rdf:Property>
<rdf:Property

</rdf:Property>
<rdf:Property

<rdfs:range rdf:resource="urn:qi4j:org.qi4j.rest.TestEntity"/>
<rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#anyURI"/>
</rdf:Property>
<rdf:Property

<rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#anyURI"/>
</rdf:Property>
<rdfs:Container

<rdfs:range rdf:resource="urn:qi4j:org.qi4j.rest.TestEntity"/>
<rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#anyURI"/>
</rdfs:Container>
<rdf:Seq
rdf:about="urn:qi4j:association:org.qi4j.rest.TestEntity:listAssociation">
<rdfs:range rdf:resource="urn:qi4j:org.qi4j.rest.TestEntity"/>
<rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#anyURI"/>
</rdf:Seq>
<rdf:Bag
rdf:about="urn:qi4j:association:org.qi4j.rest.TestEntity:setAssociation">
<rdfs:range rdf:resource="urn:qi4j:org.qi4j.rest.TestEntity"/>
<rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#anyURI"/>
</rdf:Bag>
</rdf:RDF>

Which includes quite a lot of the "schema" for the type.
RDF output of an Entity (/entity/org.qi4j.test.TestEntity/test2.rdf) of
the above type looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<rdf:RDF
xmlns:qi4j="http://www.qi4j.org/rdf/model/1.0/";
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#";>
<org.qi4j.rest.TestEntity xmlns="urn:qi4j:" rdf:about="urn:qi4j:test2">
<age xmlns="urn:qi4j:property:org.qi4j.rest.TestEntity:">12</age>
<name xmlns="urn:qi4j:property:org.qi4j.rest.TestEntity:">Xyzzy</name>
<identity
xmlns="urn:qi4j:property:org.qi4j.entity.Identity:">test2</identity>
<association xmlns="urn:qi4j:association:org.qi4j.rest.TestEntity:"
rdf:resource="urn:qi4j:org.qi4j.rest.TestEntity/test1"/>
</org.qi4j.rest.TestEntity>
</rdf:RDF>

ManyAssociation output is not yet implemented, but other than that it
works pretty well.
The HTML version of the output shows an HTML form where properties,
assocs and manyassocs can be viewed and updated. The form parsing need
to convert the form strings to native objects like longs and ints, which
is now done using an if-statement, which could be replaced by a real
converter plugin thingy.
Anyway, all in all pretty cool, and very useful for debugging I think.
If you wanna try it out, fire up the "Main" test class in the REST
extension, and browse to
http://localhost:8080/entity/org.qi4j.rest.TestEntity
