HOPE - Data supply to Europeana completed
Bardi A., Zoppi F.
This document summarizes the final implementation status of data supply from the HOPE Aggregator Infrastructure to Europeana describing: the transformation from the HOPE Common Metadata Model to the Europeana Data Model; the delivering mode implemented to supply EDM records to Europeana; the overall status of Europeana ingestion. This document is strictly related to "D3.4 - HOPE Implementation report" and "D5.4 - Content ingestion completed".Source: Project report, HOPE, Deliverable D4.4, 2013

Recommendations for the representation of hierarchical objects in Europeana
Bardi A., Kupietzky A., Isaac A., Matei D., Weber D., Arnold K., Martinez Conde M. L., Fingerhut M., Clayphan R., Bailly R., Ruhle S., Charles V., Agenjo X.
The issue of handling hierarchical objects has been always an important topic for Europeana{\textquoteright}s network of projects and Data Providers. The implementation of solutions in the Europeana portal has been delayed for a long time mainly due to the fact that complex objects required the development of new functionalities that could not be supported by the Europeana Semantic Elements (ESE) model. Indeed the simplicity and the flatness of this model prevented Data Providers from supplying complex objects.Source: Commission report, Europeana, 2013

OAIzer : customized OAI-ORE and OAI-PMH exports of compound objects for the Fedora repository
Bardi A., La Bruzzo S., Manghi P.
Modern Digital Library Systems (DLSs) are based on docu- ment models which surpass the traditional payload-metadata document model to incorporate further entities involved in the research life-cycle. Such DLSs manage graphs of interconnected objects, hence oer tools for the creation, visualization and exports of such graphs. In particular, ob- jects in the graph are exported via standard OAI-ORE and OAI-PMH pro- tocols, encoded as (XML) packages of interlinked information objects", also known as compound objects. Fedora is a well-known repository plat- form, designed to support the realization of DLSs implementing modern document models. To date, Fedora does not provide tools to customize compound object exports from DLS object graphs. This paper presents Fedora-OAIzer, an extension of Fedora which allows DLS developers to customize the structure of compound objects to be exported from a given DLS document model { expressed in terms of Fedora Content Models { and to select the OAI protocol of preference. In order to prove the com- pleteness of the approach, Fedora-OAIzer is compared to other solutions for exporting compound objects from Fedora repositories.Source: The Grey journal (Print) 9 (2013): 40–47.

Data interoperability and curation: the European Film Gateway Experience
Artini M., Bardi A., Biagini F., Debole F., La Bruzzo S., Manghi P., Mikulicic M., Savino P., Zoppi F.
Film archives, containing collections of cinema-related digital material, have been created in many European countries. Today, the EC Best Practice Network Project EFG (European Film Gateway) provides a single access point to 59 collections from 19 archives and across 14 European countries, for a total of 640,000 digital objects. This paper illustrates challenges and solutions in the realization of the EFG data infrastructure. These mainly concerned the curation and interoperability issues derived by the need of aggregating metadata from heterogeneous archives (different data models, hence metadata schemas, and exchange formats). EFG designed a common data model for movie information, onto which archives data models can be optimally mapped. It realizes a data infrastructure based on the D-NET software toolkit, capable of dealing with data collection, mapping, cleaning, indexing, and access provision through web portals or standard access protocols. To achieve its objectives EFG has extended D-NET with advanced tools for data curation.Source: Digital Libraries and Archives - 8th Italian Research Conference, IRCDL 2012, Bari, Italy, February 9-10, 2012, Revised Selected Papers, edited by Agosti, Maristella and Esposito, Floriana and Ferilli, Stefano and Ferro, Nicola, pp. 33–44, 2013

OAIzer: configurable OAI exports over relational databases
La Bruzzo S., Manghi P., Bardi A.
Modern Digital Library Systems (DLSs) typically support information spaces of interconnected objects, whose graph-like document models surpass the traditional DL payload-metadata document models. Examples are repositories for enhanced publications, CRIS systems, cultural heritage archives. To enable interoperability, DLSs expose their objects and interlinks with other objects as "export packages", via standard exchange formats (e.g. XML, RDF encodings) and OAI-ORE or OAI-PMH protocols. This paper presents OAIzer, a tool for the easy configuration and automatic deploy of OAI interfaces over an RDBMSbased DLS. Starting from the given relational representation of a document model, OAIzer provides DLS developers with user interfaces for drafting the intended structure of export packages and the automated deploy of OAI endpoints capable of exporting such packages.Source: MTSR 2013 - Metadata and Semantics Research. 7th Research Conference, pp. 35–47, Thessaloniki, Greece, 19-22 November 2013
