ALIADA (ally in Spanish, female genre) is the ally to every Library or Collection Management Software with the overall objective: to open - unlock and expose - the data managed by Library or Collection Management Software under the Linked Data paradigm, allowing external data reusing to improve the collections and/or exhibitions and to be more efficient in the creation and sharing of cataloguing metadata.

Innovations in ALIADA are:

  • ALIADA automatically generates metadata in RDF format from the input records provided by the libraries and museums in one of the following formats: MARC XML Bibliographic, MARC XML Authorities, LIDO XML or DublinCore XML. The RDF generation is performed using ALIADA ontology, which is based in the following ontologies: FRBRoo, SKOS-XL, FoaF, WGS84 and OWL-Time.
  • ALIADA automatically generates links from the generated RDF metadata to the following external datasets: DBPedia, GeoNames, Freebase, BNE, BNB, Europeana, NSZL, MARC Codes List, VIAF, LOBID Libraries & related organizations, LOBID Bibliographic Resources, Library of Congress Subject Headings and Open Library.
  • ALIADA automatically publishes the generated metadata as open data in the Linked Data cloud.


ALIADA development has been carried out following the next steps:

  • Specification of ALIADA requirements, ALIADA ontology engineering and architecture design.
  • Implementation of the first and final prototype of ALIADA with their corresponding publication phases on the open source community of GitHub.
  • Deployment of the first and final prototypes of ALIADA in the Library or Collection Management Software provided by the IT SMEs of the consortium (ARTIUM and MFAB).
  • ALIADA performance and usability monitoring over the ALIADA prototypes in order to improve its performance levels and usability in terms of users’ perception (learning curve and operation) and use easiness and maintenance requirements. This has been achieved through three workshops:
    1. the first workshop has been held with a small number of staff from the companies and institutions inside the consortium
    2. the second workshop has been held with staff (about 15 people) from the companies and institutions of the consortium
    3. the third workshop has been held with external companies and institutions.
