LoCloud aims to build on the achievements of CARARE in establishing a repository-based aggregator for Archaeological and Architectural heritage and of Europeana Local in its work with local institutions and their regional and national aggregators, which resulted in the contribution to date of well over 5 million items to Europeana.The main goals of LoCloud are: to continue to ease the task of enabling heritage organisations in making their contents accessible via Europeana, by using cloud technologies to provide services and tools which help to reduce technical, semantic and skills barriers; to facilitate aggregation of digital content from small and medium cultural institutions, to be made available to Europeana; to enable smaller institutions such as house-museums to contribute their content to Europeana; to explore the potential of cloud computing for aggregation, enrichment and re-use, with a special focus on geographic location. The new content (over 4 million items) being added to Europeana as a result of LoCloud will contribute to the critical mass of content for local heritage. Its re-use potential will also be increased by experimentation with new aggregation services which extend and enrich the content, building on technologies developed through the EuropeanaConnect (CIP ICT PSP) and PATHS (FP7) projects.
