GDI Anforderungen an GeoDRM


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.


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

GeoDRM FrameworkGeoDRM operations:

• basic operations vs. enhanced operations

• sub-set possible, depending on business model

• open number (enhanced)

• abstract and concrete interfaces


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)
