What is BIBFRAME?
“In addition to being a replacement for MARC, BIBFRAME serves as a general model for expressing and connecting bibliographic data. A major focus of the initiative will be to determine a transition path for the MARC 21 formats while preserving a robust data exchange that has supported resource sharing and cataloging cost savings in recent decades.”

Schema.org vs. BIBFRAME Schema.org way to add html tags to web pages –
that can be displaying bibliographic information OCLC doing this automatically for OCLC member
libraries Librarians can add to/authoritize schema.org
definitions BIBFRAME way to re-encode MARC in a linked
data consumeable way Not ready yet, but best we have so far? Existing MARC data will be batch transformed to
BIBFRAME BIBFRAME does have an editor, though
![Page 31: Many flavors of linked data](https://reader033.fdocuments.net/reader033/viewer/2022051613/54c660404a7959a1788b45a2/html5/thumbnails/31.jpg)
Europe is ahead of us Open linked data Europeana portal National libraries like France & Germany batch
converting bibliographic data for benefit of all libraries in the country US doesn’t really have a national library ….
DPLA metadata policies based on europeana open data agreements. No copyright in metadata
![Page 32: Many flavors of linked data](https://reader033.fdocuments.net/reader033/viewer/2022051613/54c660404a7959a1788b45a2/html5/thumbnails/32.jpg)
What I don’t know How this plays out with licensed content??
![Page 33: Many flavors of linked data](https://reader033.fdocuments.net/reader033/viewer/2022051613/54c660404a7959a1788b45a2/html5/thumbnails/33.jpg)
What I do know Tiny % of information searches begin on library
websites/in library catalogs If I Google a book title, I usually get the Google
book – including
Only helps if you are an OCLC library And searcher is looking for a book
![Page 34: Many flavors of linked data](https://reader033.fdocuments.net/reader033/viewer/2022051613/54c660404a7959a1788b45a2/html5/thumbnails/34.jpg)

What I recommend Become a joiner –
Expose metadata Big initiatives like europeana and DPLA can ingest
all kinds of metadata – including MARC OCLC is shifting everyone to the WorldShare
Metadata Collection Manager – MARC, MARCXML, MODS, DC, all kinds of data from publishers and Hathi Trust …
Educate yourself – see bibliography Advocate for openness

What I believe Don’t lose sleep! Linked data will be for discovery Data & Properties - RULE < >, encoding, screens & screens of RDF Do not matter as much as Content Quality bibliographic information
