Fig.1 STANDARD, OPEN and CLOSED CONCEPTS Fig.2 Example of STANDARD, OPEN and CLOSED CONCEPTS. First of all, a concept is a simple version of a Unified Modeling Language (UML) class. The class definition [1] is adopted to define a concept, namely: a set of objects that share the same attributes, operations, relations, and semantics.
For example, one way to represent the notion "The sky has the color blue" in RDF is as the triple: a subject denoting "the sky", a predicate denoting "has the color", and an object denoting "blue". Therefore, RDF uses subject instead of object (or entity ) in contrast to the typical approach of an entity–attribute–value model in object ...
The Metadata Object Description Schema (MODS) is an XML-based bibliographic description schema developed by the United States Library of Congress' Network Development and Standards Office. MODS was designed as a compromise between the complexity of the MARC format used by libraries and the extreme simplicity of Dublin Core metadata.
The ISO/IEC 11179 model is a result of two principles of semantic theory, combined with basic principles of data modelling. The first principle from semantic theory is the thesaurus type relation between wider and more narrow (or specific) concepts, e.g. the wide concept "income" has a relation to the more narrow concept "net income".

Gifford et al. [1] suggested the idea of file type-specific metadata automatically extracted by a file-type specific transducer. For instance, for a source code text file, metadata could include the names of the procedures that the program exports or imports, procedure types, and the files included by the program.
Learning Object Metadata is a data model, usually encoded in XML, used to describe a learning object and similar digital resources used to support learning. The purpose of learning object metadata is to support the reusability of learning objects, to aid discoverability , and to facilitate their interoperability, usually in the context of ...
