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
