Automatically compute the “best fit” mappings between any two pre-defined vocabularies. vocab 1 vocab 2 vocab 3 vocab 4 vmf VMF goal

Initial schemes to map RDA (libraries) ONIX (book/serials publishing) DDEX (recorded music) Dublin Core (web metadata) FRBR (libraries) LOM SCORM (education) MARC21 (libraries) DOI (any content) CIDOC CRM (museums and archives) FRAD (libraries) MPEG21 RDD (digital rights) RDA ONIX Framework
Vocabularies Concentrating on: Resource categories Resource-to-Resource relators Resource-to-Party relators Party-to-Party relators Party categories Metadata is increasingly seen to be more about Relators than attributes – FRBR, indecs, CIDOC CRM, RDA all Relationship based. Always been there – just hidden. 9 of the Dublin Core 15 terms are actually Relators. Semantic Web/RDF point in the same direction. Distributed data means linking identities – which means Relators.
Matrix stats Approximate figures for the matrix today: 10 schemes 53 vocabularies mapped in whole or part 500+ concept families 8000+ unique terms 30,000+ RDF triples Concentrated on resource-to-party relators (highest overlap, most important verbs) at the outset. Some further work to do before releasing the matrix publicly.
vocab 1 vocab 2 vocab 3 vocab 4 vmf Data model: the challenge The data model of the matrix has to accommodate the data models of all the vocabularies mapped to it, and the relationships between them. The VMF data model and ontology is based on Rightscom’s COA model, which grew from the <indecs> framework and has much in common with FRBR and CIDOC CRM. COA also provides the “model of making” – an analysis of the relationship between Works and their Manifestations which is of particular use in library/content provider metadata.
vocab 1 vocab 2 vocab 3 vocab 4 vmf How does VMF work? Terms are mapped into an ontology (the VMF matrix) built up from “families” of concepts based on verbs. The matrix can be queried to get the “best fit” match from one term or vocabulary to another. (Note: the matrix is for machine processing – not for human use, and it is not a cataloguing tool or a standard vocabulary).

A Concept Family provides a complete set of terms that describe a type of Event or State (“Context”), always based on a verb. A Concept Family Context Create Agent Creator Resource Creation Relator Creator_Creation Creation_Creator Relator Create_Creation Creation_Create Relator Create_Creator Creator_Create Relator Creator_Creator Relator Creation_Creation All relationships (and so most meanings) are based on Events, so this is a good place to start. Every term in the VMF matrix is a member of a Concept Family.

Value of the Concept Family (1) The Concept Families provide all possible points (“nodes”) in the matrix for vocabulary terms to be mapped.

Value of the Concept Family (2) The Concept Family allows large numbers of terms to be generated in the matrix very efficiently. A single concept will typically produce 15-25 terms (3-5 classes and 8-24 relators). Less than a quarter of those will directly map onto vocabularies, but most will be used as pathways in computing relationships between different terms. Because the model is simple in concept, and the process is reasonably flexible and automated, the maintenance of a large and complex ontology is manageable (“as simple as possible…”).
Value of the Concept Family (3) The “family tree” of verbs provide the skeleton of the whole matrix, going from the most general concepts at the top down to the most detailed anyone might need to imagine. Because of the concept families, the matrix is made up of a number of parallel hierarchies, joined across by the family links.

Some lower level verbs However granular or obscure, everything belongs to a Concept Family. The matrix should be able to include almost any concept at any level of detail – but is extended on a “need to know basis” (the principle of Functional Granularity).

Value of the Concept Family (4) The relators within a Concept Family, and between different families, create the network of meaning to allow “best fit” mappings to be computed when an exact equivalent is not available.
