FOLIO is
designed
to be
metadata
format
agnostic
• SRS separate from
operational data
• Formal SRS record
optional (Bib
and/or Holdings)
• So far, only MARC
SRS built out
• Internal
quickMARC editor

3. Modified from original https://wiki.folio.org/display/FOLIOtips/Inventory diagram by Charlotte Whitt
External
MARC
editing
available
• Cornell and other
institutions
planning to use
OCLC Connexion
for cataloging

Cataloging tool/editor

4. Linked Data on the FOLIO Roadmap
• Mid 2022
• Revive Linked Data Working Group to make sure that FOLIO’s use of Linked
Open Data (LOD) follows LOD principles, and is useful and meaningful to the
community
• 2023–2025
• Develop support for non-MARC record-based data models (for instance:
Dublin Core, VRAcore, PBCore, FGDC)
• Support entity-based data models, as well as interchange with linked open
data, including BIBFRAME
https://wiki.folio.org/display/COMMUNITY/FOLIO+Vision%2C+Strategic+Objectives+and+Initiatives

5. Wildly modified from original https://wiki.folio.org/display/FOLIOtips/Inventory diagram by Charlotte Whitt
Build out
linked
data SRS?
• Schema agnostic or
BIBFRAME specific?
• Connection to
inventory must be
schema specific
• Internal or external
editor?
External BIBFRAME
editor?
Internal
“quickBIBFRAME”
editor?

External

• Edits push updates

• Appealing path for
experimentation
even if eventual
integration
desirable

BIBFRAME includes
ways to model most
of the same things
that MARC does…
But more cleanly
and with the ability
to use URIs to name
entities…
Or to simply link to
them!

In a true transition
to linked data we
rely on these
external entities
External entity
descriptions are not
part of the local

10. Linked Data for Production: Closing the Loop
Possible prototype work integrating Sinopia and QA lookups with
FOLIO – a way to seed further linked data work in FOLIO?
• LD4P is Andrew W. Mellon funded work with partners Stanford, Iowa and Cornell in collaboration with PCC, LC &
ShareVDE, see https://ld4p.org
• Philip Schreur talked about work on the Sinopia editor and associated lookup services (QA) yesterday in the “Linked
Open Data in Open Source” session yesterday https://wolfcon2021.sched.com/event/jCk7/linked-open-data-in-
open-source
