Why Metadata?


* The primary purpose of descriptive metadata is to:


Assist researchers in the discovery of
resources relevant to their research objectives.


Assist general and/or potential audience in
discovery of resources relevant to their needs.

No Digitization Without Metadata




* Metadata is the backbone of digital curation.
* Metadata is essential!
* Without metadata a digital resource may be irretrievable,
unidentifiable or unusable.
* Metadata is descriptive or contextual information which
refers to, or is associated with, another object or
resource.

Cont.



* Metadata consists of a structured set of elements which
describe the information resource and assist in the
identification, location and retrieval of it by users, while
facilitating content and access management.


* Metadata standards formalize the element structure to
ensure that the aims of a user community can be
fulfilled.

Use of Metadata Standards

* Benefits
Ensures rich, consistent metadata which will
support the long-term discovery, use and integrity
of digital resources.
Ensures effective searching, improved
digital curation and the possibility of sharing.
Enables interoperability--metadata from a
variety of sources can be integrated into other
technical systems or machine read by compatible
ones.
The potential for resource discovery is
much greater.

Types of Metadata Standards
* Effective implementation of metadata standards needs
early consideration of the structure, content, functionality
and links between digital objects and metadata instances
required.

* Different types of metadata standards are used
interdependently to achieve the following aims:

Metadata structure standards ensure consistent
structure across individual entries; enable data
searching to be implemented and data sharing
across a discipline.

Cont.

Hierarchical structure standards enable
context as well as content to be described.


Metadata content rules enable consistent data
entry for effective searching. Content rules
include: controlled vocabularies, authority files,
thesauri, and classifications.

Conclusion
* Ensure metadata consistency and uniformity by
developing:
Metadata guidelines for dLOC member
institutions.
Best Practices for dLOC member institutions.
* Develop mapping guidelines for topical
collections.
* Provide training opportunities.
* Train the trainers.
