Hi, There are some suggestions for http://www.w3.org/1999/02/22-rdf-syntax-ns# as follows. 1. xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" xmlns:owl="http://www.w3.org/2002/07/owl#" xmlns:dc="http://purl.org/dc/elements/1.1/" maybe change to: xmlns:rdf="http://www.w3.org/tr/rdf#" xmlns:rdfs="http://www.w3.org/tr/rdf-schema#" xmlns:owl="http://www.w3.org/tr/owl#" xmlns:dc="http://purl.org/dc/elements/1.1/" So, these namespace will be stable relatively. And add dc:date or owl:versionInfo into the ontology. 2. The "Resource" had been defined by RDF Model and Sytax, not RDF Schema, So "Resource" should be rdf:Resource. and the following statment should be appended in http://www.w3.org/1999/02/22-rdf-syntax-ns#. <rdfs:Class rdf:ID="Resource" <rdfs:isDefinedBy rdf:Resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#"/> <rdfs:label>Resource</rdfs:label> <rdfs:comment>The class resource, everything.</rdfs:comment> </rdfs:Class> 3. The following statments should be appended in http://www.w3.org/1999/02/22-rdf-syntax-ns#. <rdfs:Class rdf:ID="XMLLiteral" rdf:type rdf:Resource="http://www.w3.org/TR/rdf-schema#Datatype" rdfs:comment="The class of XML literal values." /> <rdfs:Class rdf:ID="List" rdfs:comment="The class of RDF Lists." /> <rdfs:Class rdf:ID="nil" rdfs:comment="The empty list." /> <Property ID="first" rdfs:comment="The first item in the subject RDF list." /> <Property ID="rest" rdfs:comment="The rest of the subject RDF list after the first item." /> Perhaps, rdf:about, rdf:ID, rdf:RDF, rdf:Desciption should also be defined in http://www.w3.org/1999/02/22-rdf-syntax-ns#. Regards, Lotus Wu ps. A new version http://www.w3.org/1999/02/22-rdf-syntax-ns# as follows: <?xml version="1.0"?> <RDF xmlns="http://www.w3.org/tr/rdf #" xmlns:rdf="http://www.w3.org/tr/rdf#" xmlns:rdfs="http://www.w3.org/tr/rdf-schema#"> <!-- This is the RDF Schema for the RDF data model as described in the Resource Description Framework (RDF) Model and Syntax Specification http://www.w3.org/TR/REC-rdf-syntax--> <!-- New statement about rdf:Resource--> <rdfs:Class rdf:ID="Resource" <rdfs:isDefinedBy rdf:Resource="http://www.w3.org/TR/rdf#"/> <rdfs:label>Resource</rdfs:label> <rdfs:comment>The class resource, everything.</rdfs:comment> </rdfs:Class> <rdfs:Class rdf:ID="Statement" rdfs:comment="A triple consisting of a predicate, a subject, and an object." /> <rdfs:Class rdf:ID="Property" rdfs:comment="A name of a property, defining specific meaning for the property" /> <rdfs:Class rdf:ID="Bag" rdfs:comment="An unordered collection" /> <rdfs:Class rdf:ID="Seq" rdfs:comment="An ordered collection" /> <rdfs:Class rdf:ID="Alt" rdfs:comment="A collection of alternatives" /> <!--Add rdf:XMLLiteral, rdf:List, rdf:nil, rdf:first, rdf:rest--> <rdfs:Class rdf:ID="XMLLiteral" rdf:type rdf:Resource="http://www.w3.org/TR/rdf-schema#Datatype" rdfs:comment=" The class of XML literal values." /> <rdfs:Class rdf:ID="List" rdfs:comment=" The class of RDF Lists." /> <rdfs:Class rdf:ID="nil" rdfs:comment=" The empty list." /> <Property ID="first" rdfs:comment="The first item in the subject RDF list." /> <Property ID="rest" rdfs:comment=" The rest of the subject RDF list after the first item." /> <Property ID="predicate" rdfs:comment="Identifies the property used in a statement when representing the statement in reified form"> <rdfs:domain rdf:Resource="#Statement" /> <rdfs:range rdf:Resource="#Property" /> </Property> <Property ID="subject" rdfs:comment="Identifies the resource that a statement is describing when representing the statement in reified form"> <rdfs:domain rdf:Resource="#Statement" /> </Property> <Property ID="object" rdfs:comment="Identifies the object of a statement when representing the statement in reified form" /> <Property ID="type" rdfs:comment="Identifies the Class of a resource" /> <Property ID="value" rdfs:comment="Identifies the principal value (usually a string) of a property when the property value is a structured resource" /> </RDF>
