31 August 2010. 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.

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.

Shibboleth is an open source software package released by the Internet2 Consortium based on the SAML standard from OASIS. European National Mapping Agencies and leading European universities have been advancing the use of Shibboleth in operational spatial data infrastructures as part of the ESDIN project.

A ‘birds of a feather’ informal discussion meeting will take place during the week of the OGC Technical Committee meeting in Toulouse, France, 20-23 September 2010. The virtual kickoff meeting will take place on September 30th. To finalize this activity a best practice report will be presented at the OGC Technical Committee meeting in Sydney, Australia, 29 November – 3 December 2010.

The registration deadline is 30 September 2010. For more information and to register, see here: http://www.opengeospatial.org/projects/initiatives/shibbolethie. The OGC contact person for this interoperability experiment is Luis Bermudez lbermudez@opengeospatial.org.

OGC testbeds, pilot projects and interoperability experiments are part of OGC's Interoperability Program, a global, hands-on collaborative prototyping program designed to rapidly develop, test and deliver proven candidate specifications into OGC's Specification Program, where they are formalized for public release.

An OGC Interoperability Experiment is a brief, low-overhead, formally structured OGC-led activity, where members achieve specific technical objectives that further the OGC Technical Baseline. A key outcome of this activity is a formal OGC Best Practice.

The OGC® is an international consortium of more than 395 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC Standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.
