Re: ACTION-27 (ensuring that RESOLUTION of issue-12 gets into RDF Semantics)

All,


I remind you what the resolution for ISSUE-12 says:

"Mark xs:string as archaic for use in RDF, recommending use of plain 
literals instead. Recommend that systems silently convert xs:string data 
to plain literals."

By marking xs:string as archaic, we say "Do not use xs:string". I repeat 
what I said: it means that I am not welcome to say:

:myProperty rdfs:range xs:string .

Other people agreed that this triple is perfectly fine. I am sure that 
it is not the intention of most people to forbid this. It seems that the 
only problem with xs:string is when it is used as the datatype of a 
literal, like "RDF"^^xs:string .

I propose to cancel this resolution and make a new proposal:

"Recommend that publishers use plain literals instead of xs:string typed 
literals and tell systems to silently convert xs:string literals to 
plain literals without language tag."

This is very different from marking anything, like rdf:Alt, as archaic.

If the group insists to mark xs:string as archaic, I'll formally object.
