Motivation
• Evolution of GIS
• data- and desktop-centric GIS
• emerging technologies (SOA, web services)
• Spatial Data Infrastructure (SDI) concept
• Geoprocessing
• OGC Web Processing Service (WPS)
• proprietary and complex desktop-software
• increasing amount of data and higher requirements on adopted algorithms

Challenges
• Quality of Service (QoS)
• INSPIRE QoS requirements
• Cloud Computing
• general trend in mainstream-IT
• on-demand resource provisioning
• pay-per-use revenue models
• no up-front infrastructure investments

Goal
• Design a system that
• enables (OGC-) service providers to providesustainable pay-per-use business models
• define usage costs per service request, serviceuptime, accessed resource, executed process, amount of processed data, etc.
• enables (OGC-) service consumers to comparecost-benefit ratio of different service offerings
Applicable for all kind of (OGC-) services … but focus on Geoprocessing Services

Requirements
• Payment Models
• flatrate vs. pay-per-use
• Contract Models
• click-through licenses vs. long term contracts
• Accounting Models

Requirements
• Publish-Find-Bind
• additional agree phase (Publish-Find-Agree-Bind)
• OGC Technical Baseline
• existing client and service implementations shouldremain unchanged
• Security and Trust
• authentication, authorization, confidentiality, integrity, non-repudiation, protection and privacy
