>>WOWG comments on the RDF Concepts Document
>>--------------------------------------------
>>
>>We believe the RDF Concepts Document is a useful document and 
>>helpful in understanding RDF and its use.  However, out Working 
>>Group did have some concerns with respect to the issue of social 
>>meaning as discussed in this document.
>>
>>The Web Ontology WG has mixed views on this issue and could not 
>>agree on a specific consensus response in the time available. 
>>However, we note that a number of participants in the Web Ontology 
>>WG have serious reservations about the RDF view on the social 
>>meaning of RDF.
>>
>>We did reach consensus to request that the wording in the RDF 
>>Schema and the RDF Concepts documents be rephrased to explain this 
>>issue, and particularly its impact, more clearly, as this has 
>>ramifications on other languages, such as OWL, which are extensions 
>>to RDF.

>This issue is recorded as

>As before, I have recorded webont as a co-submitter.

>>-------------------------------------------
>>WOWG comments on the RDF Schema Document
>>--------------------------------------------
>>We believe that the design of the language, as reflected in the LC 
>>documents, is such that OWL can appropriately use RDF Schema and 
>>endorse this design.
>>
>>Raphael Volz of our group has prepared a detailed review of this 
>>document which he will send to the RDF Core WG.  The Web Ontology 
>>Working Group agrees with the spirit of his review (except for the 
>>comments on section 4, which was only supported by part of the WG).
>
>I see not comments from Raphael.
>
>>  We summarize our main comments below:
>>
>>i. Although this document is called RDF Schema we think that the 
>>title "RDF Vocabulary Description Language" would be clearer, and 
>>make the difference from XML Schema (used for validation) more 
>>evident.
>
>This comment has been recorded as
>
>   http://www.w3.org/2001/sw/RDFCore/20030123-issues/#webont-01
>
>RDFCore will consider this and respond in due course.
>
>>ii. Although we did not reach consensus on this, several members 
>>felt that it was unacceptable that two graphs that differ only in 
>>their rdfs:comment content would not entail each other.

>This has been recorded as

>As webont did not reach consensus, I have not added webont as a 
>co-submitter, but we are aware that Ian is not alone in his concern.

>>-------------------------------------------
>>WOWG comments on the RDF Semantics document
>>--------------------------------------------
>>We believe that the intended design of the semantics, as reflected 
>>in the LC documents, is such that OWL will be able to layer 
>>appropriately. However, we have a number of concerns that need to 
>>be addressed to improve the document and, in particular, to fix 
>>some apparent inconsistencies in the current document.
>>
>>Herman ter Horst of our group has prepared a detailed review of 
>>this document itemizing inconsistencies he has found.  The Web 
>>Ontology WG has asked Herman and the editor of our Semantics 
>>Document (Peter Patel-Schneider) to help insure that the final RDF 
>>Semantics document fixes the inconsistencies and editorial issues 
>>that are identified.
>
>Many thanks to Herman, Peter and others who are helping to improve 
>the semantics document.  I believe no specific action is needed here 
>by RDFCore other than to respond to the comments made by Herman and 
>Peter.
>
>Thanks for all your efforts Jim.  If you have any concerns, let me know.
