A good example of metadata is the cataloging system found in libraries, which records for example the author, title, subject, and location on the shelf of a resource. Another is software system knowledge extraction of software objects such as data flows, control flows, call maps, architectures, business rules, business terms, and database schemas.
The CDRL identifies what data products are to be formally delivered to the government by a contractor, as well as when and possibly how (e.g. format and quantity) they are to be delivered.
This type of "translating" from one format to another is often called "metadata mapping" or "field mapping," and is related to "data mapping", and "semantic mapping". Crosswalks also have several technical capabilities. They help databases using different metadata schemes to share information. They help metadata harvesters create union catalogs.
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.
XMPFiles for embedding serialized metadata in files, and for retrieving embedded metadata. Adobe provides the XMP Toolkit free of charge under a BSD license. [4] [2] The Toolkit includes specification and usage documents (PDFs), API documentation (doxygen/javadoc), C++ source code (XMPCore and XMPFiles) and Java source code (currently only ...
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. But like building foundations, care must ...
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".
Metadata modeling is a type of metamodeling used in software engineering and systems engineering for the analysis and construction of models applicable and useful to some predefined class of problems. (see also: data modeling).
