Jeff, FRBR has been modeled in OWL and does not have subclasses for those elements. http://metadataregistry.org/schema/show/id/5.html So it appears that the IFLA/FRBR group has a different idea on that. Instead they are each interpreted as "has-a" and "is-a" predicates. kc Quoting "Young,Jeff (OR)" <jyoung@oclc.org>: > Looking closer, my feeling is that the terms at the top of column 1 are > subclasses of Expression: > > :Abridgment > rdfs:subClassOf :Expression . > :Revision > rdfs:subClassOf :Expression . > :Translation > rdfs:subClassOf :Expression . > :Arrangment > rdfs:subClassOf :Expression . > > The Expression-to-Expression relationship properties listed below would > presumably have these domain/range settings: > > :hasAnAbridgment > rdfs:domain :Expression ; > rdfs:range :Abridgment . > :hasARevision > rdfs:domain :Expression ; > rdfs:range :Revision . > :hasATranslation > rdfs:domain :Expression ; > rdfs:range :Translation . > :hasAnArrangement > rdfs:domain :Expression ; > rdfs:range :Arrangement . > > :isAnAbridgmentOf > owl:inverseOf :hasAnAbridgment . > :isARevisionOf > owl:inverseOf :hasARevision . > :isATranslationOf > owl:inverseOf :hasATranslation . > :isAnArrangementOf > owl:inverseOf :hasAnArrangment. > > You COULD capture the information in table 5.3 in property fields of the > Expression, but then we're back to our brains falling out. > > The terms in column 3 appear be subclasses of those, but probably don't > justify being pulled out separately. > > Jeff > >> -----Original Message----- >> From: Karen Coyle [mailto:kcoyle@kcoyle.net] >> Sent: Tuesday, March 08, 2011 5:30 PM >> To: Young,Jeff (OR) >> Cc: Ross Singer; Richard Light; public-lld@w3.org >> Subject: RE: Question about MARCXML to Models transformation >> >> Quoting "Young,Jeff (OR)" <jyoung@oclc.org>: >> >> >> > I don't know the answer, but maybe we can pull together a few clues. >> In >> > the FRBR Final Report, look at Table 5.3 Expression-to-Expression >> > Relationships.
