githubcomcmh2166SWIB18LODintro

Resource Description Framework (RDF)The Resource Description Framework (RDF) is used to describe arbitrary things

RDF is based on the concept of triples which consist of subject predicate and object It is an abstract model for which several notations exist Today we will be using Turtle for our RDF serialization

Linked Data

When using RDF things are named by Uniform Resource Identifiers (URIs) By describing and

linking things graphs emerge - each statement is a graph edge

Social networks such as Facebook or LinkedIn are well-known examples of the graph approach

Linked Data PrinciplesTim Berners-Lee1 Use URIs as names for things2 Use HTTP URIs so that things can be looked up3 When someone looks up a URI provide useful

information using the standards (RDF SPARQL)4 Include links to other things so that they can

LD4P Project (and previous LD4L Labs)Exploring the path to linked data for library catalogs

Presentation 1100-1125 Tuesday

githubcomcmh2166SWIB18LODintro

LD4P Project - SinopiaBased on the Library of Congressrsquos BIBFRAME Editor (BFE) and BIBFRAME Profile Editor projects Sinopia is a linked data platform for original and cooperative cataloging using BIBFRAME and other vocabularies

Minimal viable product (MVP) release scheduled in April 2019

githubcomcmh2166SWIB18LODintro

IIIFA framework for interoperable and reusable images audio and video

All data except content datastreams is RDF using JSON-LD with a specific context and framing

linked open data convenient for viewer developers who

can treat as JSON

See httpsiiifioapi

Moving Forward with Linked Open Data

githubcomcmh2166SWIB18LODintro

Our turnLetrsquos discuss your potential uses of LOD What projects could you see for using this What support would you need to make it happen

githubcomcmh2166SWIB18LODintro

Checking Back In

Returning to the Goals from the Introductionhellip

Do you feel like you learned what you expected Needed Remaining questions

githubcomcmh2166SWIB18LODintro

Participant goals Seeing the benefits -- what benefit is there to bringing boring

library data into the linked data world Responsible for a thesaurus want to explore linked data Want to know whether RDF is an option for a digital asset management

(DAM) system that has some licensing restrictions Putting together a recommendation engine for public libraries and

would like to add layer of RDF data

githubcomcmh2166SWIB18LODintro

Mini Workshop RetrospectivePros

Good to practice hands-on

Good pace
