What is Metadata?
1. Descriptive
2. Administrative
Subtypes:
3. Structural

3. METADATA
META: about; after; higher, relating to or based on;
on an abstraction level higher than the current,
that which is about something else.
DATA: bits of information processable by computers,
but may also refer to any kind of information object or resource
composed of data, even non-digital data, such as print or film.
METADATA: data about data,
or information about information

4. The term metadata itself is a combination of the
Greek prefix meta and the Latin word data.
It is a data or information that is
about other data or information resources,
such as book, an audio file,
a scientific data set, or a digital image.
A data or information that
enables people to perform certain functions
in relation to the information resources
that the metadata is about.

METADATA
TYPES OF
METADATA

8. 1. DESCRIPTIVE
•Data elements used to describe,
catalog, or index digital resources.
•The same general type of information found in
library catalogs,but following different standards
(library bibliographic data is one kind of metadata).
Example: title, date created, subject,
digital file format

9. •Terms needed for retrieval
of individual digital objects and
sets of related digital objects
within a database.
Example: creator names, resource types,
geographical place names, time periods

11. 2. ADMINISTRATIVE
Data elements used to administer and
manage digital objects and collections.
Example: the name of the institution creating the digital objects,
date digitized, digitization equipment used ,
filename of master digital file, display file, and thumbnail file
Information lifecycle data, such as
dates of digital file creation, subsequent revisions,
time of review for retention, archiving, or disposal,
names creators and revisers of the resource,
and authorization levels for a given function.

13. Subtypes of Administrative Metadata:
a. Technical and Preservation
Metadata
Information needed for the long-term
preservation of the digital object, migration
to other digital formats as software and
hardware change over time
Examples: type of scanner used
original scanning resolution
image editing specifications

14. b. Use Metadata
May be separate from rights metadata, but
may also overlap with it.
Examples:
data about number of times an image has
been viewed.

15. c. Rights Metadata
Information on ownership, copyright, restrictions
on use and reproduction
Examples: a copyright statement;
information on restrictions on use and
reproduction of a digital image;
restrictions on access if limited to only certain
users; and
method of payment to purchase or download a
full-resolution image

16. 3. STRUCTURAL
Data elements used to internally structure
a complex digital object or provide structure
for the relationships among a set of closely related digital objects
 Examples: a single book scanned as multiple image files
(complex digital object)
Metadata needed to label each image,
to relate them to each other a part of the same complex digital object,
to structure them sequentially to allow users to navigate through them.

17. Allows the user to jump to different parts of the book
from the selected list, to enter a page number and go that page,
or to proceed page by page, backward and forward, and so on.
Multiple views of the same object,
such as front, back, and side views of the same sculpture
in separate digital image files.

19. METADATA SCHEMES AND ELEMENT SETS
MODS
Metadata Object Description Schema
Dublin Core

20. METADATA OBJECT DESCRIPTION SCHEMA (MODS)
(MODS) is a descriptive metadata schema that is a derivative of
MARC 21 and intended to either carry selected data from existing
MARC 21 records or enable the creation of original resource
description records.
It includes a subset of MARC fields and uses language-based tags
rather than the numeric ones used in MARC 21 records.

22. DUBLIN CORE
Dublin Core is an initiative to create a digital "library card catalog" for the Web.
Dublin Core is made up of 15 metadata (data that describes data) elements
that offer expanded cataloging information and
improved document indexing for search engine programs.

25. Two forms of Dublin Core exist:
1. Simple Dublin Core
It expresses elements as attribute-value
pairs using just the 15 metadata elements
from the Dublin Core Metadata Element
Set.

27. 2. Qualified Dublin Core
It increases the specificity of metadata
by adding information about encoding
schemes, enumerated lists of values, or
other processing clues.
