TL;DR: Meta-metadata as discussed by the authors is a language and software architecture addressing a metadata semantics lifecycle: (1) data structures for representation of metadata in programs; (2) metadata extraction from information resources; (3) semantic actions that connect metadata to collection representation applications; and (4) rules for presentation to users.
Abstract: Collecting, organizing, and thinking about diverse information resources is the keystone of meaningful digital information experiences, from research to education to leisure. Metadata semantics are crucial for organizing collections, yet their structural diversity exacerbates problems of obtaining and manipulating them, strewing end users and application developers amidst the shadows of a proverbial tower of Babel. We introduce meta-metadata, a language and software architecture addressing a metadata semantics lifecycle: (1) data structures for representation of metadata in programs; (2) metadata extraction from information resources; (3) semantic actions that connect metadata to collection representation applications; and (4) rules for presentation to users. The language enables power users to author metadata semantics wrappers that generalize template-based information sources. The architecture supports development of independent collection representation applications that reuse wrappers. The initial meta-metadata repository of information source wrappers includes Google, Flickr, Yahoo, IMDb, Wikipedia, and the ACM Portal. Case studies validate the approach.

TL;DR: Minnesota’s Foundations Project is a multiagency collaboration to improve access to environmental and natural resources information, and current bibliographies and reports show further background work that informed the decision-making process for such important choices as metadata schema, thesaurus and theSaurus management software, search engine, and RDF/XML standards.

TL;DR: In this paper, a method of associating metadata with a media signal receives an identifier for the media signal, uses the identifier to look up metadata in a metadata database, validates the metadata by checking attributes of the media signals relative to at least a portion of the metadata to provide validated metadata; and provides the validated metadata to a requesting application.
Abstract: A method of associating metadata with a media signal receives an identifier for the media signal, uses the identifier to look up metadata in a metadata database, validates the metadata by checking attributes of the media signal relative to at least a portion of the metadata to provide validated metadata; and provides the validated metadata to a requesting application. Related methods enable searching of metadata across metadata databases, routing metadata requests to the metadata databases, controlling access to and validating metadata for media content, and re-associating valid metadata with media content.
