ISO/IEC 11179 Standard describes the metadata and activities needed to manage data elements in a registry to create a common understanding of data across organizational elements and between organizations. ISO/IEC 19506 [41] Software Systems: ISO/IEC 19506 Standard called Knowledge Discovery Metamodel is an ontology for describing software ...
An example of a hierarchical metadata schema is the IEEE LOM schema, in which metadata elements may belong to a parent metadata element. Metadata schemata can also be one-dimensional, or linear, where each element is completely discrete from other elements and classified according to one dimension only.
Stores data elements that include both semantics and representations; Semantic areas of a metadata registry contain the meaning of a data element with precise definitions; Representational areas of a metadata registry define how the data is represented in a specific format, such as in a database or a structured file format (e.g., XML)
The result of this is a catalogue of sorts, in which related data element concepts are grouped by a high-level concept and an object class, and data elements grouped by a shared data element concept. Strictly speaking, this is not a hierarchy, even if it resembles one. ISO/IEC 11179 proper does not describe data as it is actually stored.
As with descriptive metadata, administrative metadata may be internally encoded or external to the METS document. File Section fileSec: Lists all files containing content which comprise the electronic versions of the digital object. file elements may be grouped within fileGrp elements to subdivide files by object version. Although this section ...
Metadata is often said to be "data about data", but this is misleading. Data profiles are an example of actual "data about data". Metadata adds one layer of abstraction to this definition– it is data about the structures that contain data. Metadata may describe the structure of any data, of any subject, stored in any format.
Metadata publishing is the process of making metadata data elements available to external users, both people and machines using a formal review process and a commitment to change control processes. Metadata publishing is the foundation upon which advanced distributed computing functions are being built.
The PRISM specification defines a set of metadata vocabularies. PRISM metadata may be expressed in a different syntax depending on the specific use-case scenario. Currently PRISM metadata can be encoded XML, XML/RDF, or as XMP. Each of these expressions of PRISM metadata is called a profile. Profile 1 is for the expression of PRISM metadata in ...
