Testbed-11 produced an engineering report titled: Testbed-11 Implementing Linked Data and Semantically Enabling OGC Services Engineering Report (https://portal.opengeospatial.org/files/?artifact_id=64405)

The Testbed-12 Semantic Portrayal, Registry and Mediation Engineering Report (http://docs.opengeospatial.org/per/16-059.html) introduced the concept of the Semantic Registry Information Model (SRIM), which applies several Linked Data specifications (e.g. DCAT, SKOS, VCard, FOAF etc).

The OGC Testbed-13: DCAT/SRIM Engineering Report (http://docs.opengeospatial.org/per/17-040.html) describes the implementation of a RESTful Semantic Registry that supports the Semantic Registry Information Model (SRIM) which is based on the Data Catalog (DCAT) specification. A discussion of the applicability of the SRIM to the United States Geological Survey (USGS) and the National Geospatial Intelligence Agency (NGA) metadata is also presented, including an analysis of a set of controlled vocabularies from both organizations. Best Practice guidelines for the use of SRIM are also provided. The engineering report discusses the application of Shapes Constraint Language (SHACL) to aspects of Linked Data.
