Some doubts about the Schema

Hi everybody,

Here are my doubts:


- I supposed that dc:location is described at Dublin Core Metadata Element Set [1] but I can't find any description there, nor at DCMI Metadata Terms [2].

The only reference I found is at DC-Library Application Profile (DC-Lib) [3] with the recommendation [4] of using the element "location" from the MODS (Metadata Object Definition Schema) namespace [5]

What I am missing?


- Do we need to include the dc and foaf namespaces within the EARL Schema? [6]
If so, shouldn't we include the dct namespace too?


- Apparently, the schema doesn't validate

Current:

<rdfs:Class rdf:about="http://www.w3.org/WAI/ER/EARL/nmg-strawman#SingleAssertor">
    <rdfs:label xml:lang="en">Single Assertor</rdfs:label>
    <rdfs:comment xml:lang="en">One person or evaluation tool that claims assertions</rdfs:comment>
    <owl:oneOf rdf:parseType="Collection">
      <owl:Thing rdf:type="http://www.w3.org/WAI/ER/EARL/nmg-strawman#Software"/>
-->   <owl:Thing rdf:type="http://xmlns.com/foaf/0.1/Person">	<-- (not closed)
      <owl:Thing rdf:type="http://xmlns.com/foaf/0.1/Agent">
-->   </owl:Thing>	<-- (not necessary)
    </owl:oneOf>
</rdfs:Class>

Proposed:

<rdfs:Class rdf:about="http://www.w3.org/WAI/ER/EARL/nmg-strawman#SingleAssertor">
    <rdfs:label xml:lang="en">Single Assertor</rdfs:label>
    <rdfs:comment xml:lang="en">One person or evaluation tool that claims assertions</rdfs:comment>
    <owl:oneOf rdf:parseType="Collection">
      <owl:Thing rdf:type="http://www.w3.org/WAI/ER/EARL/nmg-strawman#Software"/>
      <owl:Thing rdf:type="http://xmlns.com/foaf/0.1/Person"/>
      <owl:Thing rdf:type="http://xmlns.com/foaf/0.1/Agent"/>
    </owl:oneOf>
</rdfs:Class>

That's all.
