Assessment of OGC Web Processing Services for REST principles
This work addresses the complexity of geospatial service standards for non-expert users, but it is incremental as it focuses on assessment rather than new methods.
The paper assessed whether OGC Web Processing Services (WPS) align with REST principles to reduce complexity in geospatial web applications, concluding that adopting REST could benefit ad hoc composition of geoprocessing services for non-expert users.
Recent distributed computing trends advocate the use of Representational State Transfer (REST) to alleviate the inherent complexity of the Web services standards in building service-oriented web applications. In this paper we focus on the particular case of geospatial services interfaced by the OGC Web Processing Service (WPS) specification in order to assess whether WPS-based geospatial services can be viewed from the architectural principles exposed in REST. Our concluding remarks suggest that the adoption of REST principles, to specially harness the built-in mechanisms of the HTTP application protocol, may be beneficial in scenarios where ad hoc composition of geoprocessing services are required, common for most non-expert users of geospatial information infrastructures.
