Lexaurus Bank

Lexaurus Bank version 5 was released in December 2011. It is a powerful terminology management system for publishing term or concept based vocabularies, concept schemes, data definitions, taxonomies and thesauri.

It facilitates the import, export and cross-mapping of terminology structures in a variety of formats currently supporting SKOS, VDEX (token and nested), XVD, ESD Toolkit, Zthes,i2b2 (ontology and concept) and Snomed.

Lexaurus Bank can also synchronise with one or more Lexaurus Editors to provide collaborative editing of terminology information, including multiple users working on the same structure.

It is completely multilingual both in terms of the data it contains and the user interface for the application.

Unlike most terminology systems currently available, Lexaurus Bank maintains a full and complete history of all terms, concepts and terminology structures. This is not simply an audit trail, but provides API level access to every terminology structure at every stage in its development, together with when and who made each change.

This information is available as both a complete terminology structure for each change, or as a delta which just exposes the differences between any 2 revisions (not just the last changes).

Lexaurus Bank has been tested to a level of 10 million terms or concepts.

  • Scalable web-based repository for multiple published vocabularies to be consolidated and disseminated, organisation or sector-wide.

  • RSS feeds to notify you of updates Terminology uniqueness ensured by persistent http uris for all content.
  • Full revision management covering all aspects of terminology lifecycle.
