OGC Catalogue Services 3.0 Specification - HTTP Protocol Binding

This document specifies the HTTP profile of the CSW General Model part (see OGC 12- 168r6). The General Model specifies the abstract interfaces between clients and catalogue services. This standard specifies the mappingof the Catalogue abstract model interface into the HTTP protocol binding. In this HTTP protocol binding, operation requests and responses are sent between clients and servers using the HTTP GET and/or HTTP POST methods. Two equivalent request encodings are defined in this standard. The first using keyword-value pairs (KVP) which is suitable for use with the HTTP GET method. The second using XML which is suitable for use with the HTTP POST method. This standard defines operations that allow a client to get a service description document for the catalogue (i.e. GetCapabilities); operations that allow a client to, at runtime, interrogate the service about the kinds of data available (i.e. GetDomain); operations that allow a client to retrieve records from the catalogue (i.e. GetRecordById and GetRecords); operations that allow a client to add, modify and remove records from the catalogue service (i.e. Transaction, Harvest, UnHarvest).
