Linked Data Generation for the University Data From Legacy Database

Abstract

Web was developed to share information among the users through internet as some hyperlinked documents. If someone wants to collect some data from the web he has to search and crawl through the documents to fulfil his needs. Concept of Linked Data creates a breakthrough at this stage by enabling the links within data. So, besides the web of connected documents a new web developed both for humans and machines, i.e., the web of connected data, simply known as Linked Data Web. Since it is a very new domain, still a very few works has been done, specially the publication of legacy data within a University domain as Linked Data.In this paper our approach concentrates on publishing the data from our University's databases as linked Data on the web and also ensuring the trustworthiness of the data by addition of provenance data along with. For this purpose we have introduced a framework to make all the steps towards the Linked Data publication easy for legacy databases within a university domain.

Publishing legacy data as linked data: a state of the art survey

“…However, such approaches may fail when syntax or format of the language gets changed. Linked Data Generation described in (Sarkar et al, 2011) requires extra mappings between relational database and RDFS, where in (Sarkar et al, 2011) D2R map is used. In such cases the mapping should be specific that can work on all databases.…”

“…Authors also constructed a set of vocabularies, Web Document as Topic (WDT) with RDFS to describe the data of web documents. Sarkar et al (2011) proposed a framework called "Linked Data Generation for the University Data from Legacy Database". This approach focus on generating the University Data, such as University departments, faculties, subjects and information about different members of the University, as linked data from legacy database and publish them into the Web of Data.…”

An inference based query engine for RDF data

“…These triples are linked to each other constructing linked data cloud. The new web should be completely machine-understandable [2]. Since the start of Linking Open Data project, more and more providers publish linked data causing fast growing to linked data cloud.…”

A Semantic Based Approach for Information Retrieval from Html Documents Using Wrapper Induction Technique

“…Arup Sarkar et.al. [2] provided an approach to publish the data from legacy databases as linked data on the web thus enabling the machine readability. David Camacho et.al.…”
