A protocol for machine-readable cache policies in OGC web services: Application to the EuroGeoSource information system
Caches are used to improve efficiency in the access to certain standard geoservices. Service owners may express cache policies in natural language or enforce them by DRM. We propose a protocol based on machine-readable cache policies without DRM. Our proposal can be fully automated and used as a first step towards DRM if needed. This approach has been tested in a European project on minerals and energy resources.
