Today the Internet is an important information source, which facilitates the search and access to information contents on the Web. In fact, the Internet has become an important tool used daily by scholars in the development of their work. However the contents published on the Web increase daily and consequently difficult the identification of new contents published in various information sources. In this context the RSS technology introduces a new dimension in the access and distribution mechanisms of new contents published by distributed information sources. In the scope of scientific contents the use of RSS technology helps the scholars to be up to date of new scientific resources provided by several and distributed information sources. An instance of the OmniPaper RDF prototype has been developed in order to instantiate the mechanisms of distributed information retrieval investigated in the context of the news published in newspapers and use them in the context of scientific contents. In addition a central metadatabase was developed through the RSS approach, in order to enable the scientific content syndication. This paper intends to describe the steps involved in the development of the instantiation system of the OmniPaper RDF prototype.
