What do Libraries need to do?

1. Use the RDF data model to

publish structured data on the Web.

2. Use RDF links to interlink data

from different data sources.

Libraries & RDF

Plenty of tools already exist to allow libraries to expose data as RDF.

Become aware, experiment, work with vendors to develop

semantically compliant tools.

Trust

The largest hurdle to library adoption of Linked Data, though, may not be educational or technological …The

sticking point for librarians may be an issue of trust.

What can we do…now?

Eric Miller noted in a 2004 talk that libraries have four major roles in the semantic web:

1. exposing collections – use Semantic Web technologies to make content available;

2. web'ifying thesaurus/mappings/services;

3. sharing lessons learned;

4. persistence.
