Challenges in Academic Libraries

• Budget• Staff• Technology: Linked Data

1.Resources/Data

The Library: Users, Resources & Technology

3. Users

2. Technology

• 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

1. Resource/Data: Changes & Challenges

Resources Databases

Web, System & Data

System/AdminInterface/Web Data/DB+Library

Data: Queries, Perl, XML,index, analysis, migrationDB: Oracle, MySQL, AccessTools: MarcEdit, Excel

Programing: php, Javascript, html, etc.Publish Tools: Drupal, WordPress

Server: Shell scripting, config, maintain, etc. OS: UNIX, WindowsEditor tools: Vi, Pico

Library Data

Where is the Data?

Linked Data

• Structured data: Ontology• URI: http://viaf.org/viaf/102370574/• 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 in information:• Create, update• Store, preserve• Index, catalog• Retrieve, access

Catalog web pagesImprove findability

How could we use it?

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">Nix</span>, <span property="givenName">Garth</span>. </span> </div>

Software InfrastructurePlatformsILS: Voyager, AlephILL, Etc.

Link resolver : 360 Link library guides: LibGuidesOnline databases

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

2. Library Technology: Changes & Challenges

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

Case Study – Linked Data in DAM, IR

• Linked Data for Libraries (Cornell, Harvard & Stanford)• DAM (Digital Asset Management)• IR (Institutional Repository)

DAM

DAM --Ontology, Schema, Data

IR – Authority Control, Subject Headings

3. Users’ Needs & the Systems Librarian’s Role

Budgets

Workflow

Accessibility

- Identify needs, learn, test, implement this service to fit users’ needs- Communicate, train/guide the users to learn and use this service

Systems Librarian’s Role:

Linked Data

Save money; new service

New Skills; trainingAccuracy; Relevancy;

Data, Library Service & IT

The Key to the Future…

Data + Technology
