from SQL/MM Spatial. IBM Db2 Spatial Extender and IBM Informix Spatial DataBlade. Microsoft SQL Server since version 2008, with significant additions in the 2012 version. SAP Sybase IQ. SAP HANA as of 1.0 SPS6. Adaptations include: Implementations of the CORBA and OLE/COM interfaces detailed above are mainly produced by commercial vendors maintaining legacy technology. R: The sf package implements Simple Features and contains functions that bind to GDAL for reading and writing data, to GEOS for geometrical operations, and to PROJ for projection conversions and datum transformations. The GDAL library implements the Simple Features data model in its OGR component. The Java-based deegree framework implements SFA (part 1) and various other OGC standards. GeoSPARQL is an OGC standard that is intended to allow geospatially-linked data representation and querying based on RDF and SPARQL by defining an ontology for geospatial reasoning supporting a small Simple Features (as well as DE-9IM and RCC8) RDFS/OWL vocabulary for GML and WKT literals. As of 2012, various NoSQL databases had very limited support for "anything more complex than a bounding box or proximity search".
