Conference Paper

The WPS 2.0 Standard


Standard In this talk, we will present the Web Processing Service (WPS) 2.0 standard that is planned to be released by the Open Geospatial Consortium (OGC) shortly after FOSS4G-Europe 2014. We will describe the changes to the previous version of the standard (1.0.0) including:

• Improvements to the process description,
• Profiling mechanism for WPS processes,
• Changes to the WPS protocol, including synchronous and asynchronous invocation of processes and status monitoring,
• “Pluggable” process descriptions, and
• Improved conformance testing.

As a result of the modularization, the standard will contain several conformance classes which can be combined to tailor WPS implementations to various application scenarios. Users that run WPS 1.0 implementations will probably be interested in the planned BasicWPS, which, which bundles several modules of the new specification and is similar yet different to the previous version of the standard. Request/response examples will give the audience an exact picture of what a BasicWPS will look like. We will also describe the mechanisms that will allow domain experts to specify further extensions of the WPS core, e.g. to create a RESTful WPS, a WPS based on SensorML or a CoverageWPS. We will present the vendors planning on implementing the standard and a (possible) roadmap for creating an OGC Compliance Interoperability & Testing Evaluation (CITE) test suite that will eventually lead to certified compliant WPS 2.0 servers and also to reference implementations of the standard.
