You keep using these wordsWhat we mean by
“cooperative” and “linked data”
Cooperative cat
● WorldCat, Z39.50, etc.● Local databases● Copies of records● Consortia● Shared standards● Authorities● Listservs/email lists
● (for libraries)● Internet → Database● Shared records● Authorities● Relationships (RDF)● Common language● Open? transparent
Linked data
Thesauri and other dinosaurs
● Name authorities● Subject, genre terms● Language, geographic codes● Controlled lists of descriptive terms● Choosing from an agreed list
What do we share?Expertise
Effort
Time
Resources
Dig deep.
How does sharing feel?
Has that changed?
Do you “own” records?
Stylistic preferences?
Any pride?
Future edits?
Benefitsof sharedcatalogs
Cheaper, faster
Authority data
Direct participation

Linked dataFrom Wikipedia, the free encyclopedia
In computing, linked data (often capitalized as Linked Data) is structured data which is interlinked with other data so it becomes more useful through semantic queries.[1] It builds upon standard Web technologies such as HTTP, RDF and URIs, but rather than using them to serve web pages only for human readers, it extends them to share information in a way that can be read automatically by computers. Part of the vision of linked data is for the Internet to become a global database.
Tim Berners-Lee, director of the World Wide Web Consortium (W3C), coined the term in a 2006 design note about the Semantic Web project.[2]
Linked data may also be open data, in which case it is usually described as linked open data (LOD)[3].
What makes linked data go?
Principles● Conceptual things with HTTP URIs● Useful data attached to those URIs● Relationships between HTTP URIs (serendipity, context)Components● URIs, HTTP● Structured data, controlled vocabulary● Linked Data Platform/RDF
Wikimedia and Wikidata● Images, sounds, etc.● Huge! 55M+● Public domain
● Knowledge base● Document-oriented● Unique identifiers
★ Central repository★ Free, open★ Reduce duplication of effort
But don’t libraries hate Wikipedia???
No.… Why not?
Linked datameanslesstyping,morelinking, consistency
LC Linked Data Service id.loc.gov➔ Free➔ Open➔ Many controlled vocabularies➔ Includes relationships➔ Growing!
BIBFRAME (or whatever)
Whynot MARC?
The internet doesn’t speak MARC
We add tools between catalogs and the internet to make it go
Basic structure of BIBFRAME
records
Works, instances, items
Work: title, subject, author
Has
Instance: publication, edition
Has
Item: specific copy
Wait, what? No!
This is old hat for librariesWe share records, expertise, and resourcesWe collaborate to avoid duplication of effortWe contribute to development of standardsWe agree to play by certain rulesWe care about free, open access to data, resourcesSpoilers: some of our vendors are in on it
What can it do for us?
Tests of linked data in libraries● 2010 W3C Library Linked Data Incubator Group
Library skills, communities → linked data ● 2012 Bibliographic Framework Initiative
LLD alternative to MARC (LC, Zepheira)● 2014 LD4L (Linked Data for Libraries)
Grant collaboration to develop open source LLD● 2014 Libhub Initiative (Zepheira)
