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
• IVletadata "Wrappers" and Transport
• Collection Descriptions
• Other Standards
• Authority Standards
• Proprietary Standards
• etc..


Types of l\/]etadata Standards
• Bibliographic Description
• Metadata "Wrappers" and Transport
• Collection Descriptions
• Other standards
• Authority Standards
• Proprietary Standards
• etc..


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 21^* 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
Title Creator Subject
Description Publisher Contributor
Date Type Format
Identifier Source Language
Relation Coverage Rights


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 Ul options


Bibliographic Description Standards: MODS

• Metadata 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


Bibliographic Description Standards

• MARC
• Dublin Core
• MODS
• VRA Core


Types of Metadata Standards
• Bibliographic Description
• Metadata "Wrappers" and Transport
• Collection Descriptions
• Other Standards
• Authority Standards
• Proprietary Standards
• etc..


Metadata "Wrappers" and Transport
• Contents
• Files and Structural data
• Administrative data
• Choices
• IVIETS
• OAI-PIVIH
• No wrapper necessary


Metadata "Wrappers" and Transport: METS

• Metadata Encoding & Transmission Standard
• Standard by Library of Congress (2001)
• Contains
• Descriptions section(s)
• Administrative section(s)
• File section(s)
• Structure map(s)
• Accepts any XML schema


Metadata "Wrappers" and Transport: OAI-PMH

• Open Archives Initiative - Protocol for Metadata
Harvesting (2000-2001)
• Defines a protocol (over HTTP)
• Main Verbs
• Identify
• ListMetadataFormats - usually dublin core (99%)
• ListSets
• ListRecords


Types of Metadata Standards
• Bibliographic Description
• Metadata "Wrappers" and Transport
• Collection Descriptions
• Other Standards
• Authority Standards
• Proprietary Standards
• etc..


Collection Metadata Standards

• (METS)
• EAD
• Encoded Archival Description
• Electronic Finding Guide/Aid
• Main Sections
• Descriptions
• Container List - can link to digital objects
• Examples: ^ Univ of Florida

Evidence-based
• Universities within Florida ( 10 schools )
• Digital Objects
• MARC (linked to catalog )
• Dublin Core ( no wrapper, simple objects )
• METS wrapper (for complex items )
• MODS
• EAD for Finding Aids / Quides
• OAI-PMH Harvesting

What is XML?


• XML = eXtensible Markup Language

• Allows information and services to be encoded with
meaningful structure and semantics that computers
and humans can understand.

• Established by the World Wide Web Consortium

• This defines a book, but does not adhere to any
standard or schema


XML Schemas
• Creates a vocabulary to use
• Constrains the structure of XML data
• Defines a namespace

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
continué to follow the standards

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