Applications of Linked Bibliographic Data
June 15, 2016
Encoding Annotations from Rare Books and
Special Collections
Outline
1. Linked Data for Production (LD4P)
2. The Jacques Derrida Library at Princeton
3. Princeton’s LD4P project
4. Next steps with LD4P
Linked Data for
Production (LD4P)
Linked Data for Production (LD4P)
• Part of the LD4* family, under the Linked Data for Libraries
(LD4L) umbrella
• Multifaceted collaboration among six institutions:
• Led by Stanford, with Columbia, Cornell, Harvard, the Library of Congress, and
Princeton
• Connected to the LD4L Labs project (Cornell, Harvard, Iowa, and Stanford)
• Goals:
• Develop a new, distributed model for data exchange
• Extend core standards like BIBFRAME to cover specific domains
Linked Data for Princeton (LD4PUL)
• Four-person core group in Cataloging and Metadata Services,
plus two members from Rare Books and Special Collections
• Joined BIBFRAME Implementation Testbed in May 2014
• Participated in LD4P planning grant meetings in 2015
• Submitted subproject as part of LD4P project grant
Derrida’s Library
Portion of Jacques Derrida’s library at his home in Ris-Orangis.
Copyright ©2001 Andrew Bush. Used with permission.
Background
• In March 2015, Princeton
acquired the personal library
of Algerian-born French
philosopher Jacques Derrida
(1930-2004)
• Reflects a lifetime of
scholarship, intellectual work,
and active reading
• “I use a pencil to ill-treat the
book, to scribble, to underline,
to draw arrows” (p. 15)
Jacques Derrida.
Copyright ©2009 Pablo Secca. CC-BY 3.0.
Scope and content
• Nearly 19,000 published books and other items
• 5,897 items annotated by Derrida
• 6,770 items with personal dedications to Derrida
• Far-reaching pedagogical value:
• Literary criticism
• Translation theory
• Philosophy
• Religion (extensive and extensively annotated collection of works on Judaism)
Arrangement
• Original order was preserved to the extent possible
• Collection finding aid is divided into series and subseries based
on physical location in Derrida’s residence
• Items have been assigned a decimal identifier that indicates
their original shelf order in Derrida’s studio:
Maurice Blanchot. The Step Not Beyond
Identifier: 2.5.5.25 (M)
2 = Wall
5 = Case
5 = Shelf
25 = Position on shelf
(M) = Mezzanine

Dedications
“Downstairs were the books
I started being sent,
dedicated books. I don’t
throw any books away, and
I’m being sent quite a few,
more and more, in fact. So
all the dedicated books
stand together in
alphabetical order. There
are now many rooms full of
dedicated books” (p. 18)

Project goals
• Select 500 items with dedications, prioritizing selection of items
whose dedicators are deceased
• Create original metadata for each item using Linked Open Data
standards and vocabularies
• Convert related bibliographic data to BIBFRAME
• Integrate item-level entities with instance/manifestation-level
entities
• Produce a data set that can be used by students and scholars
Preproject and initial steps
Preproject and initial steps
• Selected 45 items with personal dedications
• Hand-coded (artisanal) RDF data using W3C Web Annotation
Model and Vocabulary as framework
• Developed exploratory queries
• Met with faculty stakeholder to discuss use cases
Modeling Annotations
• BIBFRAME 1.0 bf:Annotation class (removed from BF 2.0):
Resource that asserts additional information about other BIBFRAME resource.
• W3C Web Annotation Data Model (uses Open Annotation
vocabulary/namespace):
An Annotation is a web resource. Typically, an Annotation has a single Body,
which is a comment or other descriptive resource, and a single Target that the
Body is somehow “about”. The Annotation likely also has additional descriptive
properties.

Sample RDF in English
The resource identified by http://princeton.edu/derrida/resource/3.1.2.9
is an Open Annotation resource. It was created by J. Hillis Miller
(identified by http://viaf.org/viaf/66483274). The dedicatee of the
annotation is Jacques Derrida (identified by
http://viaf.org/viaf/88958529). The annotation has a body identified by
http://princeton.edu/derrida/resource/3.1.2.9/body1. The annotation has
a target identified by
http://princeton.edu/derrida/resource/3.1.2.9/pageX. The motive of the
annotation is dedicating.

Web Annotation Model: Challenges
• Designed for Web resources, not “Real World Objects”
• Creator of oa:Annotation cannot be distinguished from the
creator of a physical annotation that’s being transcribed
• Levels of description:
• Original (handwritten) annotations
• Meta (cataloger-assigned) annotations
Next Steps
Next steps with LD4P
• Digitize cover, title page, dedication page(s):
• Surrogates for metadata creation
• Future demos or presentation platforms
• Collaborate with stakeholders and build on work done by
others:
• LD4P Rare Materials Ontology Extension group
• Princeton Digital Humanities project
• Archaeology of Reading project
LD4P Rare Materials Ontology group
• Participants from Columbia, Cornell, Princeton, and the Rare
Books & Manuscripts Section (RBMS) of ACRL
• Working to create a BIBFRAME-compatible extension for rare
materials and special collections
• Addressing different levels of description:
• Collection
• Item
• Page
Princeton Digital Humanities project
• Princeton Center for Digital Humanities (CDH) project
• First phase will focus on a selection of materials related to
Derrida’s 1967 work Of grammatology (De la grammatologie)
• Goals:
• Make related annotations available online
• Develop protocols and workflows for all of Derrida’s annotations
Archaeology of Reading project
• Collaboration among Johns Hopkins, University College
London, and Princeton
• Focused on early modern annotations and reading practices
• Has developed a detailed XML schema for encoding
annotations
• Schema includes terms for specifying physical characteristics
of annotations
