MADS/RDF (Metadata Authority Description Schema in RDF)
type: Ontology
version info: 1.1.1
version IRI: v1-1-1
prior version: v1-1-0
comment: This document describes the MADS/RDF (Metadata Authority Description Schema in RDF) vocabulary, a data model for authority and vocabulary data used within the library and information science (LIS) community, which is inclusive of museums, archives, and other cultural institutions. It is presented as an OWL ontology. MADS/RDF is a knowledge organization system (KOS) designed for use with controlled values for names (personal, corporate, geographic, etc.), thesauri, taxonomies, subject heading systems, and other controlled value lists. It is closely related to SKOS, the Simple Knowledge Organization System and a widely supported and adopted RDF vocabulary. Given the close relationship between the aim of MADS/RDF and the aim of SKOS, the MADS ontology has been fully mapped to SKOS. Unlike SKOS, however, which is very broad in its application, MADS/RDF is designed specifically to support authority data as used by and needed in the LIS community and its technology systems. For example, MADS/RDF provides a means to record data from the Machine Readable Cataloging (MARC) Authorities format in RDF for use in semantic applications and Linked Data projects. MADS/RDF is designed to support the description of cultural and bibliographic resources. Data described using MADS/RDF, therefore, assists with identifying and annotating bibliographic and cultural resources. MADS/RDF is not focused on the description of Real World Objects. Although a MADS/RDF description may contain information specific to the Real World Object associated with the MADS/RDF authoritative label, the MADS/RDF ontology distinguishes between these two entities – the RWO and the Authority. This document is intended for those designing and implementing LIS technology systems. It is assumed the reader is familiar with MADS/XML, Resource Description Framework (RDF) for information modeling, and the SKOS/RDF vocabulary. Comments are encouraged and welcome.

Simple Type
type: Class
comment: madsrdf:SimpleType is a resource with a label constituting a single word or phrase.

Authority
type: Class
comment: A concept with a controlled label.

MADS Scheme
type: Class
comment: MADS Scheme is an organizational unit that describes a knowledge organization system. It aggregates madsrdf:Authority descriptions and/or madsrdf:MADSCollection resources included in the knowledge organization system. Including a madsrdf:MADSCollection within a madsrdf:MADSScheme should be done with care; when a madsrdf:MADSCollection is part of a madsrdf:MADSScheme, then any madsrdf:Authority within that madsrdf:MADSCollection is effectively also in the madsrdf:MADSScheme.

MADS Collection
type: Class
comment: A madsrdf:Collection is an organizational unit, members of which will have some form of intellectually unifying theme but not to the extent that it defines an independent knowledge organization system. It aggregates madsrdf:Authority descriptions or other madsrdf:MADSCollection resources.

Genre/Form Type
type: Class
comment: Describes a resource whose label is a genre or form term. Genre terms for textual materials designate specific kinds of materials distinguished by the style or technique of their intellectual contents; for example, biographies, catechisms, essays, hymns, or reviews. Form terms designate historically and functionally specific kinds of materials as distinguished by an examination of their physical character, characteristics of their intellectual content, or the order of information within them; for example, daybooks, diaries, directories, journals, memoranda, questionnaires, syllabi, or time sheets. In the context of graphic materials, genre headings denote categories of material distinguished by vantage point, intended purpose, characteristics of the creator, publication status, or method of representation.
