- 2. INTRODUCTION • Libraries have struggled with connecting a plethora of content and the metadata stored in catalogs to patrons. (Users) • Adding more value to catalogs, more tools for reference librarians, and enriched patron search, linked data is a means; to connect more people with more relevant information. • With the recent transition to the Resource Description and Access (RDA) cataloging standard within libraries, linking data in library databases has become a much easier project to tackle, largely because of another standard called Resource Description Framework (RDF).
- 3. • RDF is a simple language used to create standard data models to refer resources, their relationships and data interchange on the web. • RDF is a fundamental standard for the Semantic Web. • RDF Schema is a vocabulary extending RDF used for describing properties and classes of RDF-based resources, with semantics for generalized-hierarchies of such properties and classes.
- 4. • By generating bibliographic records in RDF, libraries can publish and interlink their metadata on the Semantic Web. • The Semantic Web is a vision about an extension of the existing World Wide Web, which provides software programs with machine-interpretable metadata of the published information and data. • A short description of the basics of the Semantic Web, the vision of its founder, Tim Berners-Lee, as well as its evolving from the concepts about Automation of information retrieval.
- 5. • The Semantic Web provides a common framework that allows data to be shared and reused across applications, enterprise, and community boundaries. • It is a collaborative effort led by W3C with participation from a large number of researchers and industrial partners. • Its objective is to convert all the unstructured documents on the web into a web data. • It is based on the Resource Description Framework (RDF).
- 6. LIBRARY PORTALS • The Library portals provide, a gateway to information, services from multiple sources and access to the organization’s resources. • The use of Semantic Web technologies in developing Library portals facilitates users’ search, access, and retrieval of learning resources. • The portal should aim to provide access to a coalition of learning repositories with learning resources available in different formats. • The implementation of Library portals with Semantic Web services will fulfill the vision of Libraries. • The large collections of learning resources are semantically annotated adopting various technologies that facilitate user’s access to the content in one or more learning repositories.
- 7. • The library portals search interface should have the capabilities for searching across the heterogeneous resources. • The Semantic Library portal should have automated interaction with a search engine at the resource, combined with web ontologies, and the content is tagged with information. • The adoption and implementation of technologies will enable ontology-facilitated sharing and reuse of learning resources. Such a portal will allow the library to provide best services.
