All
FRBRoo (version 2.0 draft of May 2013) was published as an IFLA linked data element set a couple of months ago. The element set can be found at http://iflastandards.info/ns/fr/frbr/frbroo/ The element set does not include classes and properties which are part of the general CRM, but it does include links to related CRM classes and properties. The canonical, de-referenced URIs use the CRM alphanumeric code without the English label to make them language independent, following IFLA standard practice for linked data. There is a parallel, owl:sameAs (but not de-referenced) set of lexical URIs using the full CRM label to provide backwards. The element set includes explicit inverse relationships with separate URIs, and maps them to the corresponding forward relationship, e.g. frbroo:CLP104 owl:inverseOf frbroo:CLP104i. The definitions of the inverse pairs of properties are the same, but the domains and ranges are swapped to preserve the different semantics for machine application. Labels have been disambiguated using a standard template. The element set includes the full CRM comment and a corresponding split into description and scope note to follow IFLA practice. The full set of IFLA linked data element sets for the FR family of models can be found at http://iflastandards.info/ns/fr/ <http://iflastandards.info/ns/fr/frbr/frbroo/CLP104> and more information can be found in an article on page 30 at http://www.ifla.org/files/assets/cataloguing/scatn/scat-news-42.pdf Cheers Gordon
