This document is a deliverable (D12.5 Final Implementation Report) of the ARIADNE project (“Advanced Research Infrastructure for Archaeological Dataset Networking in Europe”), which is funded under the European Community's Seventh Framework Programme. It presents results of the work carried out in Tasks: 12.3 “Implementing Integration”. The overall architecture of the ARIADNE infrastructure has been laid down by the user requirements analysis (D12.1), and the infrastructure specifications (D12.2). Initial implementation has already been described in D12.3. The goal of the ARIADNE infrastructure is to integrate data and metadata from different providers into one common schema, and also to provide semantic integration along different axes (e.g. subject, space, time). This integration intends to provide useful and user-friendly information services for archaeology. The services are intended to be available not only to researchers and related stakeholders, but also to a wider range of potential users requiring access to collections and datasets. The main goal of Task 12.3 is to accomplish the infrastructure implementation of ARIADNE. The infrastructure is specified on D12.2 and includes services such as the registry, vocabulary services, metadata enrichment services, preservation services, etc. with the following components: a) a triple store with semantic features b) the ARIADNE portal c) the MORe aggregation infrastructure d) an indexer component (Elasticsearch) e) a metadata quality measurement service f) a set of enrichment services The API specifications presented in the Annexes are especially important, as they allow developers to build on the infrastructure and deploy services. The APIs presented are REST-based and require data formats such as JSON, XML and RDF.
