MDB 2.0 is an XML Schema implementation derived from ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 6.5.2. It includes mandatory elements for describing resources that are not services. This namespace is used for metadata records that include only mandatory elements. 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.
