| Appendix
B: Glossary of Metadata Terms
Bookmark
this appendix |
| |
|
| Category List |
The simplest type
of controlled vocabulary is a high-level categorisation (or classification)
scheme. At the time of input, one or more categories must be selected
from the scheme and added to the document metadata. At the time of
seeking information, the user does not have to think of keywords,
but simply browses the list of categories and subcategories. |
| |
|
| Content Metadata |
A summary of information about
the form and content of a resource. The term ‘metadata’
has been used only in the past 15 years, but has become particularly
common with the popularity of the World Wide Web. The underlying concepts
have been in use for as long as collections of information have been
organised. Of particular interest to this Framework are the facets
of metadata intended to support resource discovery and records management.
‘Metadata’ can also be used to describe more technical aspects
of information resources; the type of information needed to transfer
information from one type of computer or software application to another.
‘Metadata’ of this type is covered in the e-GIF. |
| |
|
| DOI (digital object identifier) |
A type of persistent
identifier. A persistent identifier is a way of permanently attaching
a unique code (letters or numbers) to a document or any digital object.
If the location or URL changes, then searching for the persistent
identifier itself will find the exact object, document or original
content. |
| |
|
| Element |
One of the items
that collectively form a metadata structure. Common elements are ‘title’,
‘creator’, ‘date’ and ‘publisher’. Dividing
data into elements allows users to carry out more accurate searches
by searching on one element only. For instance, when looking for documents
by Jennifer Green, searching the ‘creator’ field only will
retrieve items by Jennifer Green only. It avoids items where the word
‘green’ appears in other contexts, as a subject, location,
etc. |
| |
|
| Element Refinement |
A sub-set of an element,
to make the meaning narrower or more specific, e.g. ‘Date created’,
‘Date destroyed’ as refinements of ‘Date’. A refined
element shares the meaning of the unrefined element, but with a more
restricted scope. A user who does not understand a specific element
refinement term should be able to ignore the refinement and treat
the metadata value as if it were the broader element, although this
will lose some precision. The definitions of element refinement terms
must be freely available. |
| |
|
| Encoding Scheme |
A scheme that controls
the content, or ‘value’ of an element or element refinement,
in order to clarify the meaning or improve resource discovery. These
schemes include controlled vocabularies and formal notations or parsing
rules. A value expressed using an encoding scheme will thus be a token
selected from a controlled vocabulary (e.g. a term from a classification
system or set of subject headings) or a string formatted in accordance
with a formal notation (e.g., '2000-01-01' as the standard expression
of a date). Encoding schemes are designed to be interpreted by machines
or by human readers. |
| |
|
| |
The definitive description
of an encoding scheme must be clearly identified and available for
use by those attempting to find information as well as those creating
the metadata records. |
| |
|
| Field |
Commonly used in
database applications to describe a space in which data of the same
type is entered (e.g. ‘title’ or ‘price’), ‘field’
is a similar concept to ‘element’. |
| |
|
| Information Retrieval |
Finding the right
information. Good information retrieval methods help ensure users
find everything they are looking for, and only what they are looking
for. |
| |
|
| Metadata Record |
A full set of structured
relevant metadata, comprising all relevant elements, describing one
information resource. A metadata record can take many forms; |
| |
|
| |
- as part of the main information resource
itself, e.g. the metadata of an XML file
- a completely separate record held apart
from the information resource itself and even in a different format
e.g. an automated library catalogue
- an electronic file held as an extension
of the main resource e.g. the ‘format’ files of a Word
document
|
| Qualifier |
Term used to refer
to both ‘Element refinement’ and ‘Encoding schemes’.
Use of this term tends to cause confusion, so it is avoided in this
document. |
| |
|
| Refinement |
See 'Element Refinement' |
| |
|
| Resource discovery |
Finding the right
stuff. See 'Information retrieval'. |
| |
|
| RFID (radio frequency identification) |
An electronic 'label'
which transmits metadata to a reader for processing. |
| |
|
| Sub-element |
Term sometimes used
to refer to an element refinement. |
| |
|
| Taxonomy |
The science of classification,
traditionally used to describe a hierarchical scheme for classifying
plants and animals. More recently it has been borrowed to describe
a classification scheme for organising networked resources and supporting
user-friendly navigation among them. Some taxonomies incorporate thesaurus
features to augment the hierarchical structure. |
| |
|
| Thesaurus |
A controlled vocabulary
designed to support information retrieval by guiding both the person
assigning metadata and the searcher to choose the same terms for the
same concept. A thesaurus conforming to ISO 2788 (=BS 5723) supports
navigation and term selection by showing relationships between terms
that are close in meaning. |
| |
|
| |
A thesaurus can help
to ensure: |
| |
|
| |
- concepts are described in a consistent
manner
- experienced users are easily able to
refine their searches to locate information easily
- users do not need to be familiar with
technical or local terminology.
