In a database driven data dictionary, the fully qualifithcfted data element name may become the primary key, or an alternate key, of a Data Elements table of the data dictionary. The data element name typically conforms to ISO/IEC 11179 metadata registry naming conventions and has at least three parts: Object, Property and Representation term.
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.
The most common standard that Naming and Design Rules are created on is XML Schema. For example, the use of upper camel case data element names is a convention used in many standard but is not specified by the XML Schema specification. Naming and Design Rules have become an important aspect of each organizations data exchange standards.
NIEM is based on several concepts from the International Organization for Standardization (ISO) 11179, which provides guidelines for the naming and definition of data elements, as well as information about the metadata captured about data elements. Part 5 of the ISO 11179 standard establishes a methodology for naming items in data dictionaries.
Some naming conventions limit whether letters may appear in uppercase or lowercase. Other conventions do not restrict letter case, but attach a well-defined interpretation based on letter case. Some naming conventions specify whether alphabetic, numeric, or alphanumeric characters may be used, and if so, in what sequence.
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 ...
Data elements usage can be discovered by inspection of software applications or application data files through a process of manual or automated Application Discovery and Understanding. Once data elements are discovered they can be registered in a metadata registry. In telecommunications, the term data element has the following components:
The Universal Data Element Framework (UDEF) was [1] a controlled vocabulary developed by The Open Group.It provided a framework for categorizing, naming, and indexing data. It assigned to every item of data a structured alphanumeric tag plus a controlled vocabulary name that describes the meaning of the dat
