General Feature Cataloguing (GFC) is an XML Schema implementation derived from ISO 19110:2016, Geographic Information - Methodologies for feature cataloging. It includes elements for cataloguing features. The XML schema was encoded using the encoding rules defined in ISO 19118, ISO 19139.

The namespace URI for gfc 2.2 is https://schemas.isotc211.org/19110/-/gfc/2.2.

gfc.xsd is the XML Schema document to be referenced by XML documents containing XML elements in the gfc 2.2 namespace or by XML Schema documents importing the gfc 2.2 namespace. This XML schema includes (indirectly) all the implemented concepts of the gfct namespace, but it does not contain the declaration of any types.

featureCatalogues.xsd implements the UML conceptual schema defined in ISO 191110:2016, Geographic Information - Methodologies for feature cataloging, Clause 6. It was created using the encoding rules defined in ISO 19118, ISO 19139.

https://schemas.isotc211.org/19110/-/gfc/2.2.0/featureCatalogues.xsd contains the following classes:

The gfc 2.2 namespace imports these other namespaces:

When revisions to these schema become necessary, they will be managed in the ISO TC211 Git Repository.
