This paper http://metadata.net/harmony/JODI_Oct2002.pdf Provides a comparison of CIDOC and Harmony. M > -----Original Message----- > From: Butler, Mark > Sent: 04 June 2003 11:21 > To: www-rdf-dspace@w3.org > Subject: CIDOC, alternative to Harmony > > > The CIDOC CRM ontology performs a similar role to the Harmony > ontology but is more extensive in scope. CIDOC's stated aim is > > "The CIDOC CRM is intended to promote a shared understanding > of cultural heritage information by providing a common and > extensible semantic framework that any cultural heritage > information can be mapped to. It is intended to be a common > language for domain experts and implementers to formulate > requirements for information systems and to serve as a guide > for good practice of conceptual modelling. In this way, it > can provide the "semantic glue" needed to mediate between > different sources of cultural heritage information, such as > that published by museums, libraries and archives." > > For a quick introduction to the ontology, see the > monohierarchies of entities and properties in this document: > > http://cidoc.ics.forth.gr/docs/cidoc_crm_version_3.2.1.rtf > > Some observations: > > - Some of the things CIDOC and Harmony (and Dublin Core for > that matter) define are pretty general, e.g. "event". It > feels like such definitions could be done in a standard layer > that ontologies like CIDOC and Harmony sit on top. > Unfortunately efforts like the IEEE SUO are much, much too > complicated - perhaps there are some more generic, less > domain specific ontologies that define things like event, > actor, place etc which ontologies like CIDOC or Harmony could > sit on? Of course in theory we don't need to worry about this > now, we can map to other ontologies later, but it's just that > I expect there are important modelling decisions here so we > might find with a bit of analysis that there are subtle > differences in the higher level entities and properties in > these ontologies (to use the jargon, they maintain different > ontological commitment) which could cause problems later. > > - Property hierarchies in CIDOC are much shallower than > entity hierarchies, as property inheritance is more complicated. > > - Representing large ontologies diagramatically is > problematic (you need a big piece of paper) but diagrammtic > representations are easier to understand than purely textual > descriptions, although they only provide a general > introduction so are not a substitute. Furthermore different > ontologies use different diagrammatic approaches. > > Dr Mark H.
