Expert Answers on Above Questions on Information Systems
Linked data is defined as a process of publishing structured data in a way that allows for interconnection and is highly useful especially during semantic queries. The basic framework of this method is based on standard web technologies such as http, URIs and RDF. It shares machine readable data instead of serving web pages, and the core principle of this concept of linked data include utilising URIs to identify entities, use HTTP to allow people to look up into these entities, and provide useful information about entities.
Linked data is highly useful in the library context as it allows for metadata from books, authors and Institutions to be published and thereby allows the user to move from one data set to another.
