vocab Vocabulary/Taxonomy Name
The name of a controlled vocabulary (defined formally) or a generic vocabulary (subject
area defined informally), taxonomy, ontology, database, term list, thesaurus, index,
etc. that is the source of the term.
Usage/Remarks
There is no fixed list of term vocabularies and each standards organization may point
to its chosen taxonomies, ontologies, keyword lists, etc. For keywords, named vocabularies
include “inspec”,
“structural engineering”, etc. For subjects, named vocabularies include “ipc”, “uns”, “unspsc”, etc. In cases where there is no named vocabulary, the @vocab attribute should be
set to “uncontrolled”.
Vocabulary Attributes
Four attributes are used in this Tag Set to identify a term from a controlled or an
uncontrolled vocabulary:
|
vocab
|
Name of the controlled or uncontrolled vocabulary, taxonomy, ontology, index, database,
or similar that is the source of the term. For example, for a subject term, a value
might be IPC Code (“ipc”) or UNS Code
(“uns”). For an uncontrolled term, the value might be
an area of study such as “structural engineering” or merely the word “uncontrolled”.
|
|---|---|
|
vocab-identifier
|
Unique identifier of the vocabulary, such as (but not limited to) a URI or DOI. For
example, for Dublin Core (DCC), the identifier might be “http://dublincore.org/documents/2012/06/14/dces/”.
|
|
vocab-term
|
The content of the element is the free prose version of the vocabulary or taxonomic
term. The @vocab-term attribute holds the canonical version of the same term, as it appears in the vocabulary.
For example, if the attribute value was “digitized-vor”, the element might contain the display text “Digitized Version of Record”.
|
|
vocab-term-identifier
|
Unique identifier of the term within a specific vocabulary, such as (but not limited
to) an item number, a URI, DOI, etc.
