MDS 1.0 is an XML Schema implementation derived from ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 6.5.2. It includes this namespace contains all classes needed for a complete metadata record for any resource. It is used for metadata records that do not include geospatial common extensions (gex), extenbsions to the schema (mex), data series (DS_*) elements (mda) or metadata for data transfer (mdt). 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 mds 1.0 is http://standards.iso.org/iso/19115/-3/mds/1.0.

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

metadataDataServices.xsd implements the UML conceptual schema defined in ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 6.5.2. 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):

The mds 1.0 namespace imports these other namespaces:
