• Resources (What): Challengesdifferent formats vs. prints more systems, repositories

• Access/Storage (Where): web based vs. physical location create & preserve the data

• Search/Discovery: (How)amount of data vs. accuracy/relevance catalog/authority control

Where is the Data?

What is Linked Data?

• Structured data: Ontology

• URI: http://viaf.org/viaf/xxx

• Relationships: Triples

• The Semantic Web:Promotes common data formats on the web.

• Linked Data

Web of Documents: URLHow does Linked Data work?

Why is it important for libraries?

• Librarians:

We put information in Information Technology.

• Add value to information:• Create, update

• Store, preserve

• Index, catalog

• Retrieve, accessCatalog web pages

Findability, data reuse

Authority Control

Software InfrastructurePlatformsILS: Voyager, AlephILL, Etc.

Link resolver : 360 Linklibrary guides: LibGuidesOnline databases

IR (Scholarly Publications): DSpaceDAM (Digital Preservation): IslandoraWebsites: Library websites

Library Technology Challenges & Linked Data

Bring traffic? Add AU control? Catalog/find them easily?

Linked Data can:

• Web traffic: 80% of hits from Google Home page redesign

• Data reuse: by other web applications • Authority control: subject headings

with URIs. Don’t have to pay vendors.• BIBFRAME: edit records faster

How could we use it? – Web sites

Structured data in HTML using attributes: schema.org

• vocab:

• typeof:

• property:

• resource:

• prefix:

<div vocab="http://schema.org/" typeof="Book">

<div><em>Author</em>: <span property="author" typeof="Person"> <span property="familyName">Gates</span><span property="givenName">Bill</span>. </span> </div>

How could we use it? – Digital Curation

• Linked Data for Libraries (Cornell, Harvard & Stanford)

• IR (Institutional Repository)

• DAM (Digital Asset Management)

- Stanford (Fedora 4)

- http://colonialarchitecture.eu/

- UNLV's Linked Data Project

Islandora – RDF & Compound Object

Linked Data in Islandora

“Islandora and Linked Open Data”, Erin Tripp, discoverygarden inc

Linked Data in Islandora – Resource Index• Indexes RDF as part

of the Resource Index.

• Provides unified "graph" of the objects and their relationships

• It can be queried using RDQL or ITQL
