Outline• Resource Description & Access (RDA)• Linked Data
– BIBFRAME– schema.org
![Page 3: RDA, Linked Data, BIBFRAME](https://reader036.vdocuments.mx/reader036/viewer/2022062412/58702cf11a28ab81258b5dad/html5/thumbnails/3.jpg)
RDA
![Page 4: RDA, Linked Data, BIBFRAME](https://reader036.vdocuments.mx/reader036/viewer/2022062412/58702cf11a28ab81258b5dad/html5/thumbnails/4.jpg)
RDA BasicsResource Description & Access• A content standard for libraries
– Successor to AACR2– Designed to cover all digital and analog resources
• Stewarded by JSC (Joint Steering Committee)– Available online & in print
• Model- and other standards-cognizant– FRBR (Functional Requirements of Bibliographic Records)– Functional Requirements for Authority Data, (FRAD)
![Page 5: RDA, Linked Data, BIBFRAME](https://reader036.vdocuments.mx/reader036/viewer/2022062412/58702cf11a28ab81258b5dad/html5/thumbnails/5.jpg)
Benefits• A structure based on the conceptual models of FRBR and
FRAD to help catalog users find the information they need more easily
• A flexible framework for content description of digital resources that also serves the needs of libraries organizing traditional resources
• A better fit with emerging database technologies, enabling institutions to introduce efficiencies in data capture and storage retrievals
![Page 6: RDA, Linked Data, BIBFRAME](https://reader036.vdocuments.mx/reader036/viewer/2022062412/58702cf11a28ab81258b5dad/html5/thumbnails/6.jpg)
RDA vs AACR2• Transcribe as found
– Abbreviations much less used than in AACR2– Record all/most parties (no “rule of three”)
• Changes in terminology• Abandons card-catalog legacy practices
![Page 7: RDA, Linked Data, BIBFRAME](https://reader036.vdocuments.mx/reader036/viewer/2022062412/58702cf11a28ab81258b5dad/html5/thumbnails/7.jpg)

OCLC & RDA• OCLC staff reviewed and commented on drafts
– FRBR work by OCLC was informative• Implementation support
– Installation of MARC changes (bib, auth, holdings)– Systematic RDA enhancements to WorldCat records– Work with communities as needed – Changes to OCLC documentation

LINKED DATA
![Page 11: RDA, Linked Data, BIBFRAME](https://reader036.vdocuments.mx/reader036/viewer/2022062412/58702cf11a28ab81258b5dad/html5/thumbnails/11.jpg)
Linked Data basics• First elaborated in a 2006 design document by
Tim Berners-Lee• A set of common practices for exposing data on
the Web in way that:– Allows many parties to participate in a Web of data– Fosters creating connections in a Web of data– Produces new knowledge and added value
![Page 12: RDA, Linked Data, BIBFRAME](https://reader036.vdocuments.mx/reader036/viewer/2022062412/58702cf11a28ab81258b5dad/html5/thumbnails/12.jpg)
Linked Data design principles• Use URIs to name (identify) things.• Use HTTP URIs so that these things can be looked up
(interpreted, "dereferenced").• Provide useful information about what a name identifies
when it's looked up, using open standards such as RDF, SPARQL, etc.
• Refer to other things using their HTTP URI-based names when publishing data on the Web.

Linked Data triples• Subject (URI or blank node)• Predicate (URI)• Object (URI, literal or blank node)
