Abstract

The use of world wide web is an important part of our lives. We use it to communicate, search for informations, online shopping and more. Its focus is on presentation and not interpretation of data, which has to be carried out by the user. Consequently, the automatic interpretation by a program or computer has become a very important requirement. With development of semantic web, which will only upgrade the world wide web, the requirement will be fulfilled and we will gain a new dimension of functionality and simplicity for users. For this purpose there already exists a standard model called RDF, which enables data interchange in a form that is understandable to machines. Nonetheless there are still many obstacles, one of them is data mapping from relational databases to RDF. Therefore the purpose of this thesis was to present one of the possible approaches with which we can achive RDB2RDF data mapping. We have developed prototype that exposes data in relational database to RDF. Also, we have enriched the exposed data with other information from open source datasets. The implemented prototype represents personal web library, with which a user can edit his book collection. In the context of research for the thesis, we have looked at some of the existing solutions and presented the technologies used in prototype development.
