Subject: [xtm-wg] Suggested recommendations for Subject Indicators choice
This is a point we unformally discussed in the Conceptual Model subgroup in Paris, I put it down before it flies away. The choice of Subject Indicators is at risk of two equally dangerous extreme ways : "chaotic" or "unique thought". The "chaotic way" : each TM author chooses its own definition of subjects, its own glossary, its own resources, yielding a very colourful but somehow unsharable Map. The "unique thought way" : every TM author references to the same unique and universal ontology, such as Dewey Decimal Classification, or Cyc Ontology, or Standard Uppper Ontology ... To keep the middle way between these two extreme ones is needed to ensure both stability, non ambiguity and sharability of TM. It seems to me we could add somewhere in the spec some prose about that, either in an Annex, or, as Murray suggested to me, in the "subject indicator" paragraph. I wrote yesterday the following draft proposition. I did not present it in plenary session because it was not really on the agenda. I put it there for what it's worth : Cheers Bernard --------------------------------------------------------------------------- -------------- "Both conceptual model and syntax leave completely free and open the choice of subjects and resources used to define subject indicators. Anyway, non-addressable subjects are potential source of ambiguity. It's therefore recommended that Topic Map authors choose, as far as possible, subject indicators among stable public URIs or URLs found in any of the various existing authoritative ontologies, indexes, thesauri, dictionaries ... to ensure non-ambiguous, durable and sharable definition of subjects. This recommendation aims only to suggest a way to make the subject definitions as non-ambiguous, accurate and stable as possible, and does not mean that anyone of such resources should be the unique reference source for any « universal definition » of subjects." --------------------------------------------------------------------------- -------------- To Post a message, send it to: xtm-wg@eGroups.com To Unsubscribe, send a blank message to: xtm-wg-unsubscribe@eGroups.com
