WagnerOverview: GeoDRM 3 GeoDRM Stack for Trading GI GeoDRM Framework Copyright Authentication Authorization Pricing & Ordering Other, e.g. WaterMarking GeoDRM Framework GeoDRM operations: basic operations vs. enhanced operations sub-set possible, depending on business model open number (enhanced) abstract and concrete interfaces

4. Name R. WagnerOverview: GeoDRM 4 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)
