The applicability document says that getMetadata should return RDF.
Because getMetadata returns XML, the applicability document is
implicitly requiring a specific mapping from RDF to XML. I wonder
whether the serialization of RDF as XML is an accepted standard, or
whether the requirement for RDF needs clarification.<br>
<br>
Possibly the applicability document should explicitly refer to
appropriate schemas and/or namespaces. For example, the XML documents
produced by my LSID getMetadata services start with an rdf:RDF tag that
specifies a variety of namespaces. Those namespaces, plus some implicit
XML schema, constrain the serialization of the RDF triples. <br>
<br>
Sample list of namespaces:<br>
<rdf:RDF xmlns:daml=<a class="moz-txt-link-rfc2396E" href="http://www.daml.org/2001/03/daml+oil#">"http://www.daml.org/2001/03/daml+oil#"</a>
xmlns:owl=<a class="moz-txt-link-rfc2396E" href="http://www.w3.org/2002/07/owl#">"http://www.w3.org/2002/07/owl#"</a>
xmlns:rdf=<a class="moz-txt-link-rfc2396E" href="http://www.w3.org/1999/02/22-rdf-syntax-ns#">"http://www.w3.org/1999/02/22-rdf-syntax-ns#"</a>
xmlns:rdfs=<a class="moz-txt-link-rfc2396E" href="http://www.w3.org/2000/01/rdf-schema#">"http://www.w3.org/2000/01/rdf-schema#"</a> <br>
<br>
Please comment on whether the applicability document requires
additional detail to specify the XML representation of RDF documents
that are produced by getMetadata. <br>
