PrestoPRIME Metadata Mapping Tool Sample Clauses

PrestoPRIME Metadata Mapping Tool. The PrestoPRIME3 project has also developed an approach for metadata mapping. In contrast to MINT, the approach is based on defining mappings between metadata models/schemas rather than starting from instances. The approach uses a high-level intermediate representation of metadata elements serving as a hub for mapping between formats. Therefore, hand-crafted one-to-one mappings between each pair of metadata formats are avoided, as the mappings for a specific pair of source and target format can be derived automatically. Metadata elements from a specific metadata format are described in relation to these generic elements. In addition, mapping templates on data type level are used. From these sources the code for a mapping problem between a pair of formats can be derived. The core of this approach is the meon ontology [6], which describes generic metadata elements and the relations between them. meon was originally developed to model metadata elements used throughout the audiovisual media production workflow in a format independent way in order to support content exchange and its automation. The meon ontology has been extended to express mapping relations between metadata formats. In addition to the ontology of generic metadata concepts, specific ontologies are created for each format taken into account. Then it is possible to infer how concepts from different metadata formats are related by observing the relations among generic concepts and to the format specific concepts. Since mapping instructions are derived from the ontology description, these mapping instructions are easier to maintain than hard coded mapping instructions. Adding a new metadata format can be done without side effects to existing definitions.
