    Library Linked Data Incubator Group: Datasets, Value Vocabularies, and Metadata Element Sets

    El objetivo del Grupo Incubador de Datos Vinculados de Bibliotecas del W3C, constituido desde mayo de 2010 hasta agosto de 2011, ha sido "contribuir a incrementar la interoperabilidad global de los datos de las bibliotecas en la Web, reuniendo a personas implicadas en actividades de la Web Semántica —centradas en los Datos Vinculados— en bibliotecas e instituciones afines, mediante el examen de las iniciativas en curso e identificando futuras vías de colaboración. Los Datos Vinculados se expresan según una normativa, como Resource Description Framework (RDF), que especifica las relaciones entre cosas y los Uniform Resource Identifiers (URIs o "direcciones Web").

    Este informe sobre Conjuntos de Datos, Vocabularios controlados y Conjuntos de Elementos de Metadatos es un complemento del informe principal realizado por el grupo. Este documento proporciona, a partir de los datos recopilados en los Casos de Uso y de las aportaciones del grupo de expertos, un resumen del estado actual de los componentes estructurales de los Datos Vinculados y en especial de aquellos que están más relacionados con los esfuerzos llevados a cabo desde el área de las bibliotecas.

    Este video de algo más de 5 minutos expresa las principales ideas del proyecto web www.mismuseos.net, un proyecto desarrollado por RIAM I+L LAB, pyme tecnológica española que trabaja en el campo de la web semántica.

    The main goal of Mismuseos.net is to present a case of exploitation of Linked Data for the G.L.A.M. community through innovative end-user applications built on GNOSS, a semantic and social software platform. Mismuseos.net is a free access semantic online solution for end-users that allows them to find and discover museums-related content, and also reach some related external information thanks to the correlation with other datasets. We currently have collections of seven Spanish museums, where users can browse over 15,000 pieces of art and 2,650 artists. The featured applications are: faceted searches, enriched contexts and navigation through graphs. The search engine enables aggregated searches by different facets and summarization of results for each successive search.

    Mismuseos.net obtains the information about cultural goods from the Europeana dataset and the online collections of public Spanish Museums. It also extracts and links data from additional datasets of the Linking Open Data cloud, either to supplement information or to generate enriched contexts: Dbpedia, Geonames and Didactalia (a GNOSS project with an index of more than 50,000 open educational resources).

    Long description:


    Mismuseos.net shows a case of exploitation of Linked Data for the G.L.A.M. community through innovative end-user applications built on GNOSS, a semantic and social software platform. In more detail, the project is guided by the following goals:

    • Put data to work: exploit public datasets and information on museums to generate benefits for users and improve the user’s experience thanks to the potential of the semantic web.
    • Link datasets both to enrich content and generate accurate contexts of information building a cultural and educational graph.
    • Connect cultural and educational worlds in a knowledge ecosystem.


    Mismuseos.net is a free access semantic online solution for end-users that allows them to find and discover museums-related content, and also reach some related external information thanks to the correlation with other datasets. Mismuseos.net structures, organizes and makes available to you, in accordance with the principles promoted by the Linked Data Project, an extensive catalog of artworks that museums publish on the Web. Moreover, it links the catalog with other existing LOD educational knowledge bases allowing the generation of educational contexts related to cultural goods.

    We currently have a collection of seven Spanish museums (a meta-museum), where users can browse over 15,000 pieces of art and 2,650 artists. These are the museums included until now: Museo Bellas Artes de Bilbao, Museo Reina Sofía, Museo del Prado, Museo Sorolla, Museo de la Fundación Lázaro Galdiano, Museo del Greco and Museo de la Biblioteca Nacional (Museum of the National Spanish Library).

    Datasets used: Europeana (CER.ES collection), Dbpedia, Geonames and Didactalia (GNOSS)

    Mismuseos.net uses several datasets and sources of information:

    • Europeana dataset, specifically the data from the CER.ES collection (CER.ES is the Digital Network of Collections of Spanish Museums), and the online collections of public Spanish Museums. These two datasets were used in order to obtain the information about cultural goods (pieces of arts and museum information basically).
    • DBPedia, used to supplement the information about the author with and extract information on authors and museums location.
    • Geonames, in order to obtain the geolocation data of artists and museums, once we have obtained the names of the places from the primary source or from Dbpedia. This information will be exploited in the future to locate them in a map view.
    • Didactalia, an index of over 50,000 educational resources on gnoss.com, linked to provide users with related educational content.

    To sum up the process, the primary information has been enriched, cleaned and normalized when necessary, and uploaded to the project online space inside the gnoss.com platform, so that we can consume and exploit the data and present the end-user applications. We have prepared a general navigation through tabs that includes a homepage with content selection, a tab for the collection (pieces of art) and another one for artists. In the near future, we will also include a tab for museums. The previous entities (pieces of art, artists and museums) are represented on the platform with their specific ontologies thanks to the semantic CMS of GNOSS using standard vocabularies if available.

    Technology and main features:

    The solution has been developed on gnoss.com, a social and semantic platform with a deep focus on the generation of social knowledge ecosystems and end-user applications in a Linked Data environment. It includes faceted searches, recommendation systems and adapted contexts in education, university and enterprises. GNOSS could be conceived as a network of networks or a linked networks space oriented to using semantic technologies for data and service integration. Moreover, it has a wide range of configurable social tools, which have been mostly deactivated in the case of Mismuseos.net.

    • Semantic Content Management System (SemCMS): semantic forms engine

    GNOSS expresses user-generated content as structured data with default basic semantic standard vocabularies. This is done automatically when a user shares content on the platform. Besides, GNOSS has an engine for developing specific ontologies to represent knowledge objects, and, as a consequence, specific search engines if necessary. The semCMS allows uploading an OWL file describing the concepts and relations within a particular knowledge domain, and it generates a semantic form with all the classes and properties represented in the OWL file. This is the case of MisMuseos.net, which has ontologies with particular vocabularies for artworks, artists and museums. So, all the information is available in RDF files.

    • Faceted searches

    Mismuseos.net has a powerful faceted search engine that is generated by its semantic graphs (RDF triplets); the search engine exploits that graphs through reasoned or inference-based searches. It provides specific configurable facets for each item type. For instance, in the case of pieces of art, users can search by facets such as collection type (sculpture, drawing, painting, etc.), museum, key words, author, time period, art techniques, etc.

    By selecting a search option, it allows you to filter the results in consecutive searchers, and therefore restrict the results to a manageable number of entries. It offers summarization of the results, so that users can better understand how the results relate to all search facets. The values are recalculated for every set of results in aggregated searches. Also, one can only filter by those options where there results, avoiding incoherent search options.

    • Contexts or related information: enriched content in Mismuseos.net

    In Mismuseos.net, we have set several contexts depending on the object or entity that the user is viewing, which offer dynamically generated content:

    1. Contexts for the entity ‘piece of art’: related works by the same artist and artworks within the same particular time period (internal), artist information (internal); related educational resources of Didactalia (external, on gnoss.com).

    2. Contexts for the entity ‘artist’: artworks of the artist (internal), contemporary artists (internal), related paper toys and educational resources of Didactalia (external).
