Interface to OGC Web-Services (OWS)

Provides an Interface to Web-Services defined as standards by the Open Geospatial Consortium (OGC), including Web Feature Service (WFS) for vector data, Catalogue Service (CSW) for ISO/OGC metadata, and associated standards such as the common web-service specification (OWS) and OGC Filter Encoding. Partial support is provided for the Web Map Service (WMS) and Web Processing Service (WPS). The purpose is to add support for additional OGC service standards such as Web Coverage Service (WCS), Web Coverage Processing Service (WCPS) or OGC API.
