Organizing principles for identity systems:
Schemat, tools for ontology-driven identity schema mapping (2006/9/9)
Schemat is a collection of Java functions for translating ontology instances and classes between formats based on the Web Ontology Language (OWL), XML and the Lightweight Directory Access Protocol Data Interchange Format (LDIF). It is intended to aid in researching the developments of ontologies to represent identity information and the mappings between ontologies, with a goal of enabling the development of standards enabling extensibility of emerging Internet protocols which exchange identity information to support decentralized localization of identity management systems.
A a new technical report which introduces schemat is now available, as is a snapshot of the schemat research software source code.
