The Open Geospatial Consortium (OGC®) calls for participation in the OGC Web Services (OWS) Shibboleth Interoperability Experiment (IE) to advance best practice for implementing standards on federated security in transactions involving geospatial data and services. Shibboleth is an open source software package released by the Internet2 Consortium based on the SAML standard from OASIS. The IE, initiated by OGC Members Cadcorp, EDINA, and Snowflake Software, will demonstrate use of Security Assertion Markup Language (SAML) with OGC Web Services, including use of Shibboleth. This IE will build on practices from the European Spatial Data Infrastructure Network (ESDIN) project and on results from previous OGC initiatives on authentication. Learn More
