The European scientific community is currently fragmented with each laboratory holding experimental data with a unique local data model and user interface, language and scheme. As a consequence, the dissemination and use of these experimental results outside of the laboratory where they are produced can be problematic. To overcome this, it is proposed to add a layer on top of the existing local databases that is accessible through a unique Data Access Portal. The aim is not to build a central database where local databases either migrate or merge but instead to provide centralised access to database nodes that are distributed over the network which are able to dialog with a central portal in a uniform manner. For achieving the aformentionoed goal a common Exchange Data Format is needed

From a conceptual point of view the Data Access Portal has been designed to act as an information space. Taking the above into consideration Data Access Portal supports two complementary modes of information retrieval: a) direct navigation mechanism which allows users to browse through the published projects by interacting with a tree view control which is always visible at the left side of the web application. This panel contains all the available published projects which are structured according to the Exchanged Data Format b) direct search functionality which is a structured keyword-based search where can be found specific information based on exchange data format keywords
