METADATA FUNDAMENTALS
Flash-course on data aggregation!
![Page 25: 2.5CR+ Content II 200+ Languages II 170+ Sources II 50Lakh ... · 2 To protect and preserve India’s cultural, academic and scientific heritage . 1 2 OPEN INCLUSIVE WINNER m Billionth](https://reader033.vdocuments.site/reader033/viewer/2022052103/603e04f4cb85744bc72d4248/html5/thumbnails/25.jpg)
WHAT IS METADATA?
● Metadata Is primarily textual information
relating to Content.
● It Includes information that enables users to
identify, discover, search, browse, interpret, or
manage Content
● Includes hyperlinks that direct users to Content
on the Source
● May include an expressive description of the
Content
NOTE: NDLI does not store contents, it only ingests metadata for Search & Browse. The content (Full-text) is delivered from Source.
![Page 26: 2.5CR+ Content II 200+ Languages II 170+ Sources II 50Lakh ... · 2 To protect and preserve India’s cultural, academic and scientific heritage . 1 2 OPEN INCLUSIVE WINNER m Billionth](https://reader033.vdocuments.site/reader033/viewer/2022052103/603e04f4cb85744bc72d4248/html5/thumbnails/26.jpg)
METADATA STANDARD
● Defines common understanding
of the semantics of the data
● Ensures correct and proper use
and interpretation of the data
● Defined through a set of fields,
vocabs (optional), and
instructions for fill-up
![Page 27: 2.5CR+ Content II 200+ Languages II 170+ Sources II 50Lakh ... · 2 To protect and preserve India’s cultural, academic and scientific heritage . 1 2 OPEN INCLUSIVE WINNER m Billionth](https://reader033.vdocuments.site/reader033/viewer/2022052103/603e04f4cb85744bc72d4248/html5/thumbnails/27.jpg)
NDLI METADATA DESIGN CHALLENGES
1 WIDE CATEGORY OF RESOURCES
Generic metadata or domain specific?
2 OPENNESS OF REPOSITORY
Closed metadata standard may fail to
describe a new resource
3 SCALE IS ENORMOUS
● Manual annotation is infeasible
● Automatic annotation guided by
crowdsourcing?
![Page 28: 2.5CR+ Content II 200+ Languages II 170+ Sources II 50Lakh ... · 2 To protect and preserve India’s cultural, academic and scientific heritage . 1 2 OPEN INCLUSIVE WINNER m Billionth](https://reader033.vdocuments.site/reader033/viewer/2022052103/603e04f4cb85744bc72d4248/html5/thumbnails/28.jpg)
NDLI METADATA REQUIREMENT SPECS
To describe any digital resource
● Generic content metadata
Contributor, Description, Language,
Format etc.
To describe domain specific resources
● Educational content metadata
Educational level, ToC, Type of learning
material etc.
● Thesis metadata
Institution, advisor, degree, researcher
![Page 29: 2.5CR+ Content II 200+ Languages II 170+ Sources II 50Lakh ... · 2 To protect and preserve India’s cultural, academic and scientific heritage . 1 2 OPEN INCLUSIVE WINNER m Billionth](https://reader033.vdocuments.site/reader033/viewer/2022052103/603e04f4cb85744bc72d4248/html5/thumbnails/29.jpg)
TRANSLATION ISSUES
➢ Variation in Subject classification standards
● Dewey Decimal Classification (DDC)
● Library of Congress Classification (LCC)
● Library of Congress Subject Headings (LCSH)
➢ Mapping terminology for different languages
● Translate when equivalent terminology is present
● Transliterate otherwise
![Page 30: 2.5CR+ Content II 200+ Languages II 170+ Sources II 50Lakh ... · 2 To protect and preserve India’s cultural, academic and scientific heritage . 1 2 OPEN INCLUSIVE WINNER m Billionth](https://reader033.vdocuments.site/reader033/viewer/2022052103/603e04f4cb85744bc72d4248/html5/thumbnails/30.jpg)
SO WE COLLECTED CONTENT.
HOW DO WE ENSURE RELEVANCE?
HOW DO WE PROPAGATE USAGE?
HOW DO WE GENERATE MORE VALUE?
HOW DO WE ENSURE SUSTAINABILITY? HOW DO WE GROW?
