GeoDRM Working GroupGeoDRM Working Group

• Part of Open Geospatial Consortium (OGC) – where geospatial standards are defined

• GeoDRM Working Group – comprises of content providers and technology providers

• Charter is not to invent new digital rights technologies but to reuse and extend for geospatial data and services

• Formed in June 2004 – Graham Vowles, Roland Wagner, Joe Cardinale Co-chairs

• Last meeting June 13-16, St John’s, Newfoundland, Canada.

Today we rely on our legal framework and licence agreements to protect our intellectual property

Our business is shifting so we need alternative ways to manage and protect our intellectual property

OWS3

Program2: GeoDRM.OWS3 TestbedProgram2: GeoDRM.OWS3 Testbed

• Goal– Development and Specification of an OGC interoperable “License

Click-Through” Mechanism for users to acknowledge a license prior OWS access

– Cascadable architecture

• Execution Time Frame: April 18th – October 30th

• Members– Abstract: IFGI-Fraunhofer_ISST-con terra– Implementation: Cubewerx, lat-lon, UniBW Munich,

IFGI-Fraunhofer_ISST-con terra

• Status/Results– [On going]– Draft Specifications

Program3: GeoDRM.Interoperability ExperimentProgram3: GeoDRM.Interoperability Experiment

• Goal– Ensure consistency between technology fragments– Interoperability Experiments between OGC identified and developed

technologies and solutions (GeoDRM.Demonstrator, GeoDRM.OWS3, DP Web Pricing & Ordering, DP GeoXACML)

– Authentication, Authorization, Click-Through Licensing, Pricing & Ordering

• Execution Time Frame: September- November• Members

– 30 days call for participation, expected end of July 2005

• Status/Results (expected)– [Planed]– IE Reports, Change Requests for OGC Specification Development

Demonstrator OWS3 Interop. Experi.



ConclusionConclusion

• GeoDRM WG focus on highly needed functions: authentication, authorization, click-through license, pricing

• Developing a GeoDRM Reference Model to formally define the problem

• Developing a GeoDRM Framework to rights enable a network of services

• Specifications need to be interoperable and consistent• First drafts expected in November 2005• Closely related to Data and Service Sharing aspects of

INSPIRE work program.
