United States : OGC requests comment on Publish/Subscribe standards for geospatial data.

Members of the Open Geospatial Consortium (OGC) request comments on the candidate OGC Publish/Subscribe Core (PSC) 1.0 Interface Standard and the OGC Publish/Subscribe SOAP Binding (PSSB) 1.0 Interface Standard.

These candidate OGC standards define core concepts and mechanisms for enabling the Publish/Subscribe messaging pattern with OGC Web Services. Publish/Subscribe may be used independently of or in conjunction with the Request/Reply messaging pattern specified by many existing OGC Web Services. The Publish/Subscribe messaging model is distinguished from the Request/Reply model in that it provides for an ongoing, persistent expression of interest (a subscription) and the asynchronous delivery of messages typically containing or referencing geospatial data that match the subscription.

The candidate OGC Publish/Subscribe Core 1.0 Interface Standard defines a common conceptual framework and functionality, independent of particular binding technologies such as KVP, SOAP and REST.

The candidate OGC Publish/Subscribe SOAP Binding 1.0 Interface Standard specifies an extension to OGC Publish/Subscribe 1.0 Core to allow for Publish/Subscribe communications using the SOAP protocol.
