1OVERVIEW OF LINKED DATAIntroduction:The report describes the concept of linked data and various associated tools. The reportfirst gives a brief overview of the linked data like what is meant by linked data, for what purposethe technology used. The following section after the brief overview is followed by the associatedtools of linked data technology. The tools and techniques and their functionalities has beendescribed in details in this section. The next sections talks about the practical implementationsof the technology and for this some practical projects based on the linked data concept hasbeen mentioned. The report also outlines the comparison between linked data and NOSQL, a populardatabase technology used for modern database design. The comparison describes theimportant features of the respective technologies and how this features has helped in solvingvarious problems in the particular fields for which the technology is adopted.
2OVERVIEW OF LINKED DATAConcept of linked data:The concept of link data is fairly simple and straightforward. It involves the use of theWeb to create link between various resources. The sources can be diverse to such an extentthat it may belong to the databases deployed in two different organization situated in twodifferent geographical locations or it may involve two different systems maintained by the sameorganization that has not been linked before due to complexity of interconnection techniques[1]. There are certain referred to as 'Linked Data principles', which must be followedto successfully publish and connect data resources by making use of the web infrastructurewhile referring to the architecture and standards as described by the article.Technologies used for linked data:Two of the most prominent technologies that are used for the Linked data are UniformResource Identifier (URIs) and Hyper-Text Transfer Protocol (HTTP) [2]. The concept of URIThe concept of uniform resource identifier or URI is little different than the traditionalURL technique and it generalize the process of identifying resources on the web space so thatmore options are available when someone looks for any information.The concept of HTTP:Entities, which use the http:// scheme for identification, can be looked by the URIs.This feature enables the HTTP to be used for creating a simple yet universal mechanism forresource identification.The RDF technology:Another technology that supplements the URIs and HTTP is the ResourceDescription Framework or popularly known as RDF [3]. RDF is used to provide a generic modelbased on the graph based data modeling to outline the structure with which the data has to belinked [4]. Case study ofAdoption of linked data technology in practical project:Linking Open Data project:The most prominent example where the linked data principle has been successfullyadopted is the Linking Open Data project [6]. The community is supported by the W3CSemantic Web Education and Outreach Group. The project identifies existing data sets that isavailable under the open licenses and then the data sets are converted to RDF as per theLinked Data principles to publish them on the web.The Digital Public Library of America (DPLA):
