Specification of the technologies chosen. Deliverable D 4.2

The current report builds on the findings of D4.1 with the results of Tasks T4.3, an empirical estimate and evaluation of potential commercial data contributors, and T4.4, an evidence-based technical specification for aggregating such data at scale. The current state of theory and practice in data integration is reviewed, focussing on efforts to achieve cultural-commercial sector interoperability, and potential solutions for the problem at hand are considered for feasibility given the limited resources. An experiment was undertaken to assess the feasibility of applying Linked Heritage's existing data integration format, LIDO, and aggregation platform, MINT, to the previously identified industry standard metadata formats. The experiment's focus was the ONIX for Books 3.0 mapping described explicitly in Linked Heritage's Description of Work, although DDex for recorded music, EIDR for audiovisual materials and IPTC for photos were also investigated. This was done with the knowledge and cooperation of the relevant standards bodies, to achieve a reliable and standardised result in accordance with accepted industry best practice. http://www.linkedheritage.eu/index.php?en/142/documents-and-deliverables
