Metadata Standards




Why Metadata Standards?





Standards


"The nice thing about standards is


there are so


many to choose from.


- Andrew Tannenbaum ( 1988 )





Types of Metadata Standards

Bibliographic Description Standards



MARC


* Dublin


Core


* MODS

* VRA Core






Bibliographic Description Standards: MARC

MARC
Originally developed in 1960s by Library of Congress
Most embraced metadata standard in libraries

MARC 21
Combination of USMARC and CAN/MARC
Metadata standard for 21st century

MarcXML
Same MARC format, except encoded in XML






Bibliographic Description Standards: MARC


MARC

Positives:
Can encode a very granular amount of data
Very well adopted and works well with machine readers
Negatives
Not very human-readable
High learning curve
Mixes data with display (as commonly implemented)






Bibliographic Description Standards: DC

Dublin Core

Originally developed between 1994 and 1995 in Dublin Ohio
by OCLC

Used widely on web pages to assist search engines

Simplified Dublin Core

Bibliographic Description Standards: DC

Dublin Core

Qualified Dublin Core
Added three elements (Audience, Provenance, RightsHolder)
More importantly, added some basic refinements
Positives
Widely accepted and easy to read and encode
Negatives
Even with qualified dublin core, difficult to encode complex data
Lack of data refinement leads to loss of UI options






Bibliographic Description Standards: MODS

SMetadata Object Description Scheme

Developed in 2002 by Library of Congress
Beginning to be the de facto standard for digital libraries
(MODS/METS)
Positives
Can handle a (large) subset of MARC tags
Handles complex objects and can easily be extended
Negatives
Hard to do round trip portability from MARC MODS MARC






Bibliographic Description Standards: VRA Core

Visual Resource Association

Developed in 1996 by Visual Resource Association

Used for describing visual/cultural materials

Includes all the standard tags
Date, Title, Description, Rights, Subject, etc..
Also more unique tags
Cultural Context
Style
Technique

Lessons / Standards


Conclusions


* Try not to tie your metadata to your system
Archival vs. Service

* Don't be afraid of extending for your own needs, but
continue to follow the standards

* Don't cripple your metadata / Prepare for the most
information you would want
METS / MODS v. simple Dublin Core
