RDF core: a component for effective management of RDF models
Floriana Esposito, Luigi Iannone, Ignazio Palmisano, Giovanni Maria Semeraro · 2003
In order to make Semantic Web effective, the first step was the development of languages that could support data portability, namely XML, metadata descriptions, namely RDF, and ontology management and inference, such as DAML+OIL, OWL etc. Those languages have to be manipulated by applications and many Application Programming Interfaces (APIs) have been developed in order to accomplish this task. Obviously, they differ in implementation details. Moreover, developers often would like to exploit more than an API at a time. Another issue is that a developer would be very advantaged if he could have a uniform support for some services across these frameworks (such as query languages), despite the lack of standards. In this paper, we present a component, called RDFCore, developed in order to overcome these problems. We will also illustrate the added value that our framework provides to RDF in order to exploit the full potentiality of the language and to employ it in research as well as in real world applications. Consequently we will provide some test results on the performances of the presented framework. 1
