Term Definition
Context [top] As related to data, ‘context’ can describe the perspective, significance,
connotation and/or environment of data assets. Context is the relationship of
data assets to other concepts that aid in their discovery, use and
comprehension. See Data Context (DRM Usage)
Enables the intended meaning of data to be more clearly known. This is often
done through categorisation of data. Such categorisation also facilitates the
discovery of data. (Context also includes business rules which will be covered
in a later version of the DRM.)
Context Artefact [top] An example of a Context Artefact is a Taxonomy.
Context Item [top] A set of terms or phrases that are organised in lists, tree structures or
networked relationships.
Controlled Vocabulary
[top]
Controlled Vocabulary
Registration Authority [top]
A list of terms that have been enumerated explicitly. This list is controlled by
and is available from a controlled vocabulary registration authority. All terms in
a controlled vocabulary must have an unambiguous, non-redundant definition.
NOTE: This is a design goal that may not be true in practice; it depends on how
strict the controlled vocabulary registration authority is regarding registration of
terms into a controlled vocabulary. At a minimum, the following two rules
should be enforced:
1. If the same term is commonly used to mean different concepts in different
contexts, then its name is explicitly qualified to resolve this ambiguity.
2. If multiple terms are used to mean the same thing, one of the terms is
identified as the preferred term in the controlled vocabulary and the other terms
are listed as synonyms or aliases. (ANSI/NISO Z39.19-200x)
An entity that controls and makes available the set of terms within a controlled
vocabulary.
CRUD [top] Database operations Create, Read, Update, and Delete.
Data [top] A value, or set of values, representing a specific concept or concepts. Data
becomes ‘information’ when analysed and possibly combined with other data in
order to extract meaning and to provide context. The meaning of data can vary
according to its context. (DRM usage)
Information in a specific physical representation, usually a sequence of
symbols that have meaning; especially a representation of information that can
be processed or produced by a computer. (RFC2828, Internet Security
Glossary)
A re-interpretable representation of information in a formalised manner suitable
for communication, interpretation or processing. (ISO/IEC 11179-3)
A representation of facts, concepts or instructions in a formalised manner,
suitable for communication, interpretation or processing by humans or by
automatic means. (ISO/IEC 2382-4 as per ISO/IEC 11179-1)
Data Access [top] Requests for data services, such as a query of a Data Asset. (DRM usage) See
Query and Query Point.
