Library Linked Data

Linked Data

Today's libraries are also incorporating the linked data standards to compete with the changing technological needs of libraries all over the world. With changing web technologies, libraries cannot remain unaffected, they need to change their data/metadata description and access technologies based on the web technologies to make the library data findable on the web in the similar way as other data.

When linked data standards are used in the bibliographic data of libraries in order to ease the visibility and accessibility of library resources within the library systems and outside the library system then it is called Library Linked Data. A library linked data is more structured, defined and well connected library data using Semantic web technologies. It may be called the alternative to MARC data.

BIBFRAME is the bibliographic data model which uses Linked data principles in bibliographic data to make the data more searchable and interoperable library data on the web. It is released by the Library of Congress (BIBFRAME version 2.0) in 2016 to replace MARC.

Libraries are involved in creating the library linked data by using the linked data standards like RDF (Resource Description and Framework) for linking data using Triples. These triples can be linked to one another through the use of URIs (Uniform Resource Identifiers) which are the permanent identifier for the objects on the web.

Another Linked data standard is RDA (Resource Description and Access) for cataloging data which is computer readable and replace MARC cataloging standards. RDA makes the data more searchable by general web searches. Library of Congress and British Library are already using the RDA cataloging.

Linked Data

To make the data on the web more manageable and accessible, it is necessary to make that data well described, structured and interlinked using some web technologies so that it gives user better experience in searching and accessing information.

Linked data makes the web of data more structured, organized and accessible. Linked data is a method of describing data on the web in order to link with related data to make the browsing more efficient. It uses standard web technologies such as HTTP, URIs and RDF in order to serve information to the computers.

It is also called the collection of interrelated datasets on the web. Examples of large linked datasets are Wikidata and DBpedia. DBpedia essentially makes the content of Wikipedia in RDF (Resource Description Framework). Not only this, It incorporates links to other datasets on the web and by incorporating those extra links (in form RDF triples) application may provide a much better user experience in terms of getting related knowledge on a particular topic.

The inventor of the World Wide Web Tim Berners-Lee has stated the four principles of Linked data in his 2006 design note.

Linked Open Data
Like many other terms open education, open access, open source, etc. Open data is also the data which is free from any copyright laws and accessible to everyone to use, reuse and share. when related open data is interlinked then it is called Linked Open Data. Example of DBpedia given above is Linked Open Data example.
