Today's tools and models
MARC (at the end of its life)
FRBR (a model, but based on past practices)
RDA (based on FRBR and AACR and MARC, with some new concepts).

Where do we need to go?

Cutter's questions
What books does the library have by this author?
What books does the library have on this topic?
Does the library have a book with this title?

Who else was writing in this time in this place?
Given this subject, who are the key authors?
![Page 19: Kcoyle@kcoyle.net Yes, we can! Some observations on library linked data](https://reader033.vdocuments.site/reader033/viewer/2022061306/551488cf550346b2598b4e85/html5/thumbnails/19.jpg)

What are related subjects?
Information about the subject (encyclo/wiki/pedia)
Persons and institutions related to the subject.
![Page 20: Kcoyle@kcoyle.net Yes, we can! Some observations on library linked data](https://reader033.vdocuments.site/reader033/viewer/2022061306/551488cf550346b2598b4e85/html5/thumbnails/20.jpg)
Seeking books, or seeking knowledge?
BOTH! But users have learned to come to the
library only to seek books.
![Page 21: Kcoyle@kcoyle.net Yes, we can! Some observations on library linked data](https://reader033.vdocuments.site/reader033/viewer/2022061306/551488cf550346b2598b4e85/html5/thumbnails/21.jpg)
Where we could goSemantic web – to interact with data from other communities, ending the library data silo
Navigation and discovery for users that takes better advantage of the data and leads users to new discoveries
Computable data – ability to mine bibliographic data for information
Expansion of library data through discovery of new communities of interest.
![Page 23: Kcoyle@kcoyle.net Yes, we can! Some observations on library linked data](https://reader033.vdocuments.site/reader033/viewer/2022061306/551488cf550346b2598b4e85/html5/thumbnails/23.jpg)
Similarities are as important as differences
Where do we find the similarities in library data?
Answer: in authoritative headings; in controlled lists, in fixed (data) fields; in
some text fields

Everything is connected to something
No (or few) dead ends
Computation is "easy" (e.g. topic maps, term clouds, timelines)
Users can discover previously unseen connections between information resources.

Some issues - FRBR
Not well understood
Untested, mostly unimplemented
Superceded by FRAD, FRSAD, and now requiring changes to be compatible
Group 1 (WEMI) may impede interaction with non-FRBR-ized metadata.
![Page 40: Kcoyle@kcoyle.net Yes, we can! Some observations on library linked data](https://reader033.vdocuments.site/reader033/viewer/2022061306/551488cf550346b2598b4e85/html5/thumbnails/40.jpg)
More issues - FRBR
Group 3 (Subjects) should be replaced with a general subject relationship to anything that can be identified
Group 3 elements should be general (e.g. Place) or be subproperties of a more general property
Placement of data elements within WEMI is highly debated, especially for collective items (books of essays, multiple music works on a disk).

Some issues - RDA
Not well understood
Untested, mostly unimplemented Adheres strictly to FRBR (which may be
undergoing changes)
Every RDA element is valid only as a single FRBR entity.

RDA – properties, relationships, controlled values; still provisional
FRBRer - completed
FRAD – in progress
ISBD – in review

To Do
Test FRBR and RDA in a linked data environment
Simplify where possible
Create links between library data and non-library metadata
Encourage use of library data outside of libraries
Encourage use of non-library data inside libraries.
