This schema is composed of all the MPEG-7 tools in the proposed MPEG-7 User Description (UD) Profile that are used by ETSI TS 102 822-3-1 V1.1.1 (2003-05) Metadata Schema. Constraints on these tools called for by the UD profile have been implemented by removal of restricted elements and attributes. The UserActionType has been extended in the ETSI TS 102 822-3-1 V1.1.1 (2003-05) metadata schema. Constraints are indicated by embedded comments. The schema is divided into three modules: Module 1 contains schema components used both for content description and user description; Module 2 contains schema components used for content description only and Module 3 contains schema components for user description only. Within each module the structure reflects the table structure in AN393: global attribute groups, followed by simple types and then complex types (ordered alphabetically within each category). MODULE 1. MPEG-7 SCHEMA COMPONENTS USED BY TVA BOTH FOR CONTENT DESCRIPTION AND FOR USER DESCRIPTION 1A. GLOBAL ATTRIBUTE GROUPS USED BY TVA BOTH FOR CONTENT DESCRIPTION AND FOR USER DESCRIPTION 1B. SIMPLE TYPES USED BY TVA BOTH FOR CONTENT DESCRIPTION AND FOR USER DESCRIPTION 1C. COMPLEX TYPES USED BY TVA BOTH FOR CONTENT DESCRIPTION AND FOR USER DESCRIPTION MODULE 2. MPEG-7 SCHEMA COMPONENTS USED BY TVA FOR CONTENT DESCRIPTION ONLY MODULE 3. MPEG-7 SCHEMA COMPONENTS USED BY TVA FOR USER DESCRIPTION ONLY 3A. SIMPLE DATATYPES USED BY TVA FOR USER DESCRIPTION ONLY 3B. COMPLEX DATATYPES USED BY TVA FOR USER DESCRIPTION ONLY
