  2. “Geographic Information Science & Technology Body of Knowledge 2 – Foundational Research” • NSF funded 2010-2013 • NSF GSS Award 0964563 • Goal: • Envision, implement, demonstrate foundations for BoK2 • Team: • CUNY - Hunter College • Brigham Young Univ • San Diego State Univ • New Mexico State Univ • http://gistbok.org/ • Key questions: • What is the BoK? • How to operationalize it? • What can it be used for? • How can it evolve?

  6. Triple Store Versioning with RDF tag* V1.2 Concept 1 Concept 2 V1.0 V1.5 V1.5b Concept 3 Concept 4 Each concept will be tagged with a version number*. The current version will be designated with a “b” tag (i.e. V1.5b). This tag will be given to all concepts that are yet to be approved. Applications can access any version through the use of the versioning tag field. V1.4 Concept 5 *Bedi, P. and M. Sudeep, 2007, Versioning OWL Ontologies using Temporal Tags.

  8. Authoritative Product • A "top down" approach in which experts in those disciplines review additions/changes to the GIS&T BokOnto to determine what concepts are accepted in the next version (traditional editor). • Scores for confidence in a new concept and its connections could be generated from the bottom up in a collaborative fashion through assertion and debate by the community (Ahearn et al., 2013) . • Scores for new concepts could be inferred through data mining of the contributors publications to generate a weight for each concept they wish to add/modify. The concepts parent would be used for the scoring metric. • Scores could for new concepts could be determined through the nature (confirmation of existing content, correction, or revision) of a contribution (Keßler and de Groot, 2013).
