Models and Tools for Aggregating and Annotating Content on ECLAP

In the area of cultural heritage there is a strong push on aggregating content metadata from institutions (such as museums, university, archives, library, foundations, etc.) to make them widely accessible. This action is going to reduce fragmentation, allows aggregation and integrates valuable collections in a unique place. For example, European a (the so called European digital library) collects only metadata, while content files are referred via some URL. These URLs refer to the original content owner and/or to the Content Aggregator, facilitating the collection. That model leaves space to the Content Aggregator to provide additional services on their enriched models. The proposed Content Aggregation model attempts to satisfy specific requirements with a semantic model and tools providing support for executable aggregations such as: play lists, collections, e-learning courses, and media annotations/synchronizations. The produced aggregations may also be provided by mapping semantic concepts to European a. The paper also performs an analysis of semantics models mentioned and of their difficulties including some comments about the adoption of linked open data and media model. The results have been produced in the project ECLAP ICT PSP founded by the European Commission, http://www.eclap.eu.
