CAT 1.0 is an XML Schema implementation derived from ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 7.4.4. It includes elements for codelist catalogues, and example catalogues. The XML schema was encoded using the rules described in ISO/TS 19139:2007, Clause 8 and implementation approach from ISO/TS19115-3, Clause 8.

The namespace URI for cat 1.0 is http://standards.iso.org/iso/19115/-3/cat/1.0.

cat.xsd is the XML Schema document to be referenced by XML documents containing XML elements in the cat 1.0 namespace or by XML Schema documents importing the cat 1.0 namespace. This XML schema includes (indirectly) all the implemented concepts of the cat namespace, but it does not contain the declaration of any types.

catalogues.xsd implements the UML conceptual schema defined in ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 7.4.4. It was created using the encoding rules defined in ISO 19118, ISO 19139, and the implementation approach described in ISO 19115-3 and contains the following classes (codeLists are bold): AbstractCT_Catalogue, and AbstractCT_Item

codelistItem.xsd implements the UML conceptual schema defined in ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 7.4.4. It was created using the encoding rules defined in ISO 19118, ISO 19139, and the implementation approach described in ISO 19115-3 and contains the following classes (codeLists are bold): CT_Codelist, CT_CodelistCatalogue, and CT_CodelistValue

crsItem.xsd implements the UML conceptual schema defined in ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 7.4.4. It was created using the encoding rules defined in ISO 19118, ISO 19139, and the implementation approach described in ISO 19115-3 and contains the following classes (codeLists are bold): CT_CRS, CT_CoordinateSystem, CT_CoordinateSystemAxis, CT_CrsCatalogue, CT_Datum, CT_Ellipsoid, CT_Operation, CT_OperationMethod, CT_OperationParameters, and CT_PrimeMeridian

uomItem.xsd implements the UML conceptual schema defined in ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 7.4.4. It was created using the encoding rules defined in ISO 19118, ISO 19139, and the implementation approach described in ISO 19115-3 and contains the following classes (codeLists are bold): CT_UnitOfMeasure, and CT_UomCatalogue
