Re: comment: working draft on n-ary relations note

  Dear Natashia,

Thank you for your kind reply. I understand well that the solutions 
proposed by the SWBP group concern only the W3C-supported languages; the 
problem (if any...) is that such languages are inherently binary, and 
that any solution (independently from the specific problem of 
"purchase") that will try to transform them into n-ary languages will 
always be, probably, "odd" and "artificial" to some extent.

On the other hand, the three examples you proposed in your working paper 
are clearly examples of "narratives", i.e., of documents or document 
fragments where the main part of the information content consists in the 
description of "events" concerning some "actors" (characters, 
personages, etc.)  the term "event" is taken here in its more general 
meaning, covering also strictly related notions like fact, action, 
state, situation etc. These actors try to attain a specific result, 
experience particular situations, manipulate some (concrete or abstract) 
materials, send or receive messages, buy, sell, deliver etc. Narratives 
are extremely important from an economic point of view, given that they 
represent the essential part of corporate knowledge documents (memos, 
policy statements, reports, minutes etc.), news stories, normative and 
legal texts, medical records, many intelligence messages, etc. Their 
importance is, by the way, demonstrated by the fact that you have felt 
there was a need to to take them into account, see you working paper. 
Unfortunately, narratives cannot be dealt with in a satisfactory way 
with the actual RDF/OWL-like tools, whether or not this should be a 
cause of concern to W3C.

With best regards,
