3 GDI Anforderungen an GeoDRM
Datum: Name: Dr. Roland M. Wagner (IFGI),

4 Problem Statement Geo-data is a valuable good, because of high efforts to capture and maintain it. Geo-data can be inappropriately/illegally copied, modified, used and re-used. Digital Protection Methods (GeoDRM) will motivate producers to publish or otherwise make geo-data available. GeoDRM as a tool should ensure re-financing of investments. GeoDRM technologies need to be smart to be accepted by customers. Insufficient incentives motivating users to use “third-party” data producers. Name: R. Wagner OGC GeoDRM Ansätze

5 GeoDRM WG Overview Digital Rights Management – how to manage data ownership and rights management GeoDRM Working Group – formed during OGC TC June 2005, Southampton Charter is to tap into mainstream DRM technologies and extend for the geospatial usecase Lower GeoDRM (authentication, authorization, licensing, pricing&ordering) first, because of urgent need GeoDRM Working Group – defining vision and understanding business problem Name: R. Wagner OGC GeoDRM Ansätze

8 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 Weak DRM Strong DRM encryption no protection wartermarking managed access copyright statement click-through licence Name: R.

12 GeoDRM Stack for Trading GI
GeoDRM Framework GeoDRM operations: basic operations vs. enhanced operations sub-set possible, depending on business model open number (enhanced) abstract and concrete interfaces Other, e.g. WaterMarking Pricing & Ordering Licensing Authorization GeoDRM Framework Authentication Name: R. Wagner OGC GeoDRM Ansätze

13 General Requirements Re-use of existing geoDRM solutions,
Security, Pricing & Ordering, Copyright, Licensing, water marking Support of multiple mainstream protocols SAML, OSCI,… “Embedding without touching” Principle Clear separation with (Framework-Interface) Drivers Support for multiple (OGC) protocols All Protocols are based on HTTP, working on-the-fly and state-less Short-term: Client-Service Architecture, no third Object (e.g. Trust Center) Name: R.
