The **OGC Reference Model** describes a framework for the ongoing work of the [Open Geospatial Consortium](/source/Open_Geospatial_Consortium) (OGC) and their specifications and implementing interoperable solutions and applications for geospatial services, data, and applications. It is not an OGC standard.

It has the following purposes:

- Provides a foundation for coordination and understanding (both internal and external to OGC) of ongoing OGC activities and the Technical Baseline;

- Update/Replacement of parts of the 1998 OpenGIS Guide;

- Describes the OGC requirements baseline for geospatial interoperability;

- Describes the OGC architecture framework through a series of non-overlapping viewpoints: including existing and future elements;

- Regularize the development of domain-specific interoperability architectures by providing examples.
