Description: Abstract:
Three different projects are depicted that show the application of techniques and tools of the semantic approach to data, in order to expand and improve the information services provided to different types of users. The three take advantage of the state of the science, and are compelled by legal mandates.The project "Analysis of the application of Semantic Web technologies in digital collections of libraries, archives and museums in Catalonia and Spain", is been developed within the framework of the Research Group "Culture and Digital Contents", and is been funded by the Autonomous Government of Catalonia. This research leverage the opportunities offered to the collections of libraries, archives and museums by the open data regulation within the European Union (Directive 2013 /37 / EU of the European Parliament and of the Council of 26 June 2013 laying amending Directive 2003 /98 / EC on the reuse of public sector information). According to this act, this cultural heritage collections and related metadata become a potential base for digital content products and services and have a huge potential for innovative re-use in sectors such as learning and tourism. Wider possibilities for re-using public cultural material should, inter alia, allow Union companies to exploit its potential and contribute to economic growth and job creation. It includes two stages:
  • A first stage has been the analysis of how and to what extent the RDF data model is applied in major Spanish digital collections of heritage materials. During the period 2014-2015, 51 digital repositories are analyzed, determining whether each of them expresses their records in RDF, offers SPARQL query points searchable by external agents, and uses references as property values. A paper is being published, that concludes that the use of RDF is unequal and excessively conditioned to the use of applications to automatically convert records in RDF triples.
  • As a continuation of the first stage, during the period 2015-2016 we are seeking solutions to the problem of enrichment RDF data with external links. Or, as required by the fourth principle of Linked Data, how to include links within the bibliographic and authority data to other URIs, so that the user can discover more things”. The envisaged end result is a module which will enrich DSpace for RDF data with semi-automatic external links in the process of cataloging. This development will use semantic web technologies, like RDF, OWl, SPARQL, and other well known technologies, like Python and RESTful API.
Within the framework of the Group Adaptabit, a working group on digital accessibility for teaching, research and teaching innovation, two different projects are being developed.
  • Since 2013, a project is being conducted to design a workflow for the creation, description, publication and dissemination of learning resources in video media. One of the main goals is designing a metadata schema to describe accessibility and educational aspects of those videos, in order to let the users with disabilities to look for and retrieval them according to their specific needs and expectations. For this purpose, the broader model of Access for All has been taken into account, the metadata schemas LRMI and MPA have been adapted, and the semantic technology of microdata have been leveraged. Durant the following months, we are going to apply this model to the Digital Repository of the University of Barcelona, based on DSpace, and we are going to study the benefits of using microdata for searching and positioning learning resources on the search majors (Google, Yahoo and Bing). The funding institution is the University of Barcelona.
  • Since 2014, a project is being conducted to convert the content of the legislation acts in force over Catalonia –at the regional, State and European levels- into RDF, in order to publish them as Linked Open Data. This process is based on International standards in relation to the scheme for identification of legislative acts (URIs), the scheme for structuring the content, and the ontologies for representing the bibliographic entities, agents, events... related to those acts. The ultimate goal is to provide information to citizens and businesses for the enrichment of other datasets and generation new products and services. In addition, in partnership with the DAMA research group, linked to the Politechnical University of Catalonia, a graph-based database management system will be applied to the new RDF dataset in order to improve the search systems of the Catalan legislative acts. The FUNDING institution is the Catalonia Official Journal and Publications Entity of Catalonia Government (EADOP).
