題目 ECLAP Content and Metadata, Selection, Aggregation and Augmentation
描述 As regards content description (see Section 2), the ECLAP project focussed on WP4 Content Provision and Augmentation involved the selection and delivery of content and metadata for a wide range of user communities as well as the definition of the harvesting metadata schema and its semantic mappings to a spectrum of commonly used standards. The major task has been to create the mappings between the descriptive and multimedia metadata, to ensure the semantic interoperability inside the ECLAP system and more importantly with the Europeana system. To this end, the report provides description of the metadata ingestion processes; ECLAP metadata schema; interoperability is achieved in the ECLAP domain; mapping statistics from content providers to the ECLAP portal; mapping of the elements of ECLAP to the Europeana Data Model; overview of the procedures and tools that are deployed within ECLAP, in order to establish interoperability between ECLAP’s metadata and the Europeana repository in EDM, and metadata interoperability best practices adopted in order to ensure uniform access to the ECLAP and Europeana content.
For the Content selection and contextualization, Section 3 describes the activity performed on content for its selection, enrichment and aggregation. To aggregate content also means to contextualize a single resource in relation to other elements or resources: on ECLAP, content can be compared and contextualized at a transnational level, as the aggregation activities which can be performed on the portal allow content providers to relate their own items to those provided by other partners. For these reasons, the wide range of possibilities offered by ECLAP to further enrich and contextualize the resources and connecting them through users’ annotations and tools such as Mystoryplayer and the Social Graph are particularly useful for the purposes of research and education. Both these tools have been selected by Europeana and included into the Europeana pro web pages.
For the technical aspects and tools for content enrichment, ECLAP provided a range of metadata enrichment activities (based on AXCP media grid). The typical metadata enrichments performed by ECLAP can be the addition of technical descriptors of source files, the addition of more languages, the geo localization passing from location named into metadata and descriptors to formal GPS position, the production of QR codes for museum inspection and linkage (see it as augmented reality first step), the content aggregation, the addition of comments and tags, the association of taxonomical classification, the establishing of connections with dbPedia open data, the addition of a formal IPR license descriptor, the association of univocal date and time, the association of any kind of identifiers, the production of LOD model, the content aggregations, etc. As a result, the content is described in terms of metadata based on the so called ECLAP semantic model.
