Future work The future work is described in detail in chapter 10. Copyright © 2007 Open Geospatial Consortium vii Foreword The contents of this document are the result of a multi-organization collaboration during the OGC Web Services 4.0 Test Bed, GeoDRM thread. The document describes a trust model that enables the exchange of trusted messages between OGC services and clients. The document is intended as an OGC Discussion Paper. It does neither cancel nor replace other OGC documents in whole or in part. Two other documents are also planned as result of OWS4.GeoDRM: The GeoDRM Engineering Viewpoint and Supporting Architecture in OWS4 OGC 06-182 and the OWS Common Change Proposal OGC 06-177. The intention of this document is to complement the other two documents. The model presented in this document is based on the model described in WS-Trust. Other parts of this document, especially the implementation reference other security standards specifications from IETF, W3C, OASIS and ISO. Most notably, the following standards are referenced: WS-Security, WS-Trust, XACML, SAML.
