Metadata Approach
 General Meaning: Data about data
 In our library world:
 Machine understandable structured data
(intrinsic and extrinsic) describing various
attributes of an Information object for the
purposes of bibliographic control and use
management, for examples:
 VRA (The Visual Resources Association) Core
Categories
 DC (Dublin Core)
 Encoded Archival Description (EAD)

Four Levels of Understanding Dublin
Core
 Simple Dublin Core vs Qualified Dublin Core
 Dublin Core in HTML, and Dublin Core in
XML without DTD (Document Type
Definition)
 Dublin Core in XML with its own Namespace
and DTD
 Dublin Core in XML with Schema, in RDF
(Resource Description Framework) format

The Birth of A Standard
 The Dublin Core Metadata Workshop Series began in
1995, with an invitational workshop which brought
together librarians, digital library researchers, content
experts, and text-markup experts to promote better
discovery standards for electronic resources.
 Organized by OCLC and the National Center for
Supercomputer Applications (NCSA) to address the
problem of providing metadata for network-accessible
materials.
 The Dublin Core is a 15-element set of descriptors
that has emerged from this effort in interdisciplinary
and international consensus building.

Goals
 Simplicity of creation and maintenance
 Commonly understood semantics
 Conformance to existing and emerging
standards
 International scope and applicability
 Extensibility
 Interoperability among collections and
indexing systems

Imagine there's no heaven
It's easy if you try
No hell below us
Above us only sky
Imagine all the people
Living for today . . .
Imagine there's no countries It isn't hard to do
Nothing to kill or die for
And no religion too
Imagine all the people
Living life in peace . . .
Imagine no possessions
I wonder if you can
No need for greed or hunger A brotherhood of man
Imagine all the people
Sharing all the world . . .
You may say I'm a dreamer
But I'm not the only one
I hope someday you'll join us And the world will be as one

Two broad classes of qualifiers
Element Refinement.
 These qualifiers make the meaning of an element
narrower or more specific. A refined element shares
the meaning of the unqualified element, but with a
more restricted scope.
Encoding Scheme.
 These qualifiers identify schemes that aid in the
interpretation of an element value. These schemes
include controlled vocabularies and formal notations or
parsing rules.

Document Type Definition
DTD defines what
tags can go in your
document, what
tags can contain
other tags, the
number and
sequence of the
tags, the attributes
your tags can have,
and optionally, the
values those
attributes can have.
