• The Open GIS Consortium (OGC)
–
Not-for-profit, international consortium
–
250+ industry, government, and university members
(about 1/3 from Europe)
• Specification Development Program (since 1994)
– similar to other Industry consortia like W3C, OMG, etc.
–
Class A liaison with ISO/TC211
• Interoperability Program (since 1999)
– a global, innovative, hands-on engineering and testing program designed to accelerate interface development and bring interoperability to the market
• Outreach and Community Adoption Program
(since 2002)
– awareness raising, education and training, encourage take up of OpenGIS® interfaces, business development
–
Subsidiaries: OGC Europe
, OGC Australia, …
OGC Vision
A world in which everyone benefits from geographic information and services made available across any network, application or platform.
OGC Mission
Our core mission is to deliver spatial interface specifications that are openly available for global use.

Ways of managing and protecting Intellectual
Property
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

• 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
