Information is now at reach for everybody everywhere on the internet. But originally the library was the centre of information. It has a tradition in the development of formats for description of publications and related materials. MARC is the bibliographic standard in the library even nowadays.  Classification systems and thesauri helps to structure information. ISSN and ISBN are early systems of unique identification. The internet saw an exponential growth of information, in general but specifically for science. New metadata schema’s and ontologies have been developed with Dublin Core as the most notorious. With the rise of Internet scientific information is expanding where publications are only a part of it. But a main feature of the Internet is the capacity of linking. Therefore information has to be described as objects that are uniquely identified and can be interpreted by machines. While most of the internet metadata is still based on text, the philosophy of Linked Data is changing this approach. The development of a virtual research and educational network is conducted by six universities (Camague, Holguin, Pinar del Rio, UCI, UCLV and Oriente) in the framework of the ELINF project which is a part of the 6+6 year VLIR-UOS programme ‘NETWORK University Cooperation: Strengthening of the ICT role in Cuban Universities for the development of the society’. It is supported by the Ministry of Higher Education of Cuba and other local stakeholders. The ELINF project is building an information network where information objects can be integrated and reused. It links library systems with learning environments, repositories and research information platforms. It is developing connections between different types of information: people, organizations, projects, courses and publications. Central in this approach are the authority tools, vocabularies, thesauri and ontologies. The project has chosen to use only open source software solutions. It works with specific platforms for educational, library and information management and research output, respectively  Moodle, ABCD, DSpace and VIVO and create an integrated environment. The partner universities are in different stadia of implementing the platforms. A strategy and policy of interoperability is developed. The project is developing new tools and modules to realize interoperability between the different products: e.g. ABCD 3.0, Darkaiv and EsFacil. It is a work in progress
