ALIADA is an open source solution designed by art libraries and museums, ILS vendors and experts on Semantic Web to help cultural heritage institutions to automatically convert, link and publish their library and museum data as Linked Open Data. If they can export their metadata as MARCXML or LIDOXML, they can choose ALIADA as their ally in the challenge of liberating cultural institutions from their current data silos and integrating library and museum data onto the Semantic Web. ALIADA uses its own ontology based on FRBRoo, SKOS, FoaF and WGS84, the ontologies most used by the linked open datasets analyzed during the design of the tool. It's expected this ontology to be updated with the new emerging models and vocabularies, such as RDA or BIBFRAME, according to the ALIADA's community demand. ALIADA can be integrated with the current management system in a library or a museum allowing non-expert staff to easily select and import metadata into ALIADA. Once the file is validated, the user can start the "RDFizer" to create the triples using the existing mapping templates. All the MARC mappings were not carried out into RDF using FRBRoo ontology because of the complexity of the format. Along with the RDF conversion, ALIADA provides a set of predefined SPARQL queries to check the URIs. The next step in the workflow is the linking to other datasets. ALIADA offers a list of external datasets that can be linked to, including Europeana, DBpedia or VIAF. Finally, ALIADA will show the dataset before publishing it on the DataHub.
