    En este interesante artículo escrito por miembros del departamento de Servicios Web (CMS & Search) de la empresa alemana Daimler AG (Mercedes) y el Instituto de Informática de la Universidad de Leipzig, los autores plantean cómo el enfoque de integración de datos comúnmente aceptado y basado en XML, web services y arquitecturas orientadas a Servicios (SOA) puede ser superado por un enfoque y la aplicación de las posibilidades que brinda el paradigma de los datos enlazables (Linked Data) mostrando ejemplos y casos de uso en diversos ámbitos de la empresa.

    Sharing cultural heritage the linked open data way: why you should sign up

    Cultural heritage institutions are beginning to explore the added value of sharing data. We report on Dutch initiatives that have started opening up their data through far-reaching open licenses as well as initiatives that are using the Linked Open Data cloud to integrate and enriching heritage collection metadata.

    As galleries, libraries, archives and museums (GLAMS) are redefining their role as nodes in a wider network of content creators and providers, open innovation becomes key. GLAMS across the world are beginning to explore the added value of sharing data resources following the so-called Linked Open Data (LOD) principles. In this paper, we provide an overview of the practical uses and implications of using Linked Open Data through four projects currently running in the heritage domain. We have chosen these four projects among many because they show the usage of Linked Open Data from different perspectives. In this article, we first introduce the most important aspects of open data and linked data, for those not familiar with it yet (Sections 2 and 3). We shall then present four projects that are active in contributing or using linked data in Section 4, followed by a discussion of risks and advantages and concluding remarks in Section 5.

    European Data Forum

    tipo de documento Hiperesteka

    European Data Forum

    EDF is the yearly meeting place for industry, research, policy makers, and community initiatives to discuss the challenges and opportunities of Big Data in Europe. These aspects have both a technical - in terms of technology and infrastructure needed to master the volumes, heterogeneity, and dynamicity of Big Data - and a socio-economic component, speaking about emerging types of products and services and their commercialization, innovation and business models, but also policies and regulations.

    Our aim is to bring together all stakeholders involved in the data value chain to exchange ideas and develop actionable roadmaps addressing these challenges and opportunities to strengthen the European data economy and its positioning worldwide. The roadmaps will be offered as a contribution to the definition of research, development, and policy activities at the level of the European Union institutions and those of its member states.

    An equally important goal of the European Data Forum is to create and foster a truly European Big Data community. This emerging community will enable promising ideas to move from the stage of research questions all the way to successful deployment and the acquisition of capital; in the same time, its stakeholders will mutually reinforce commercial strategies that require a forward looking, dynamic, and well-integrated EU-wide venture capital and industry. This will in turn depend establishing in the European Data Forum a culture of evidence based reasoning and positive criticism where ideas from any part of the community acquire value by being examined and discussed in the context of reliable quantitative information (e.g. about industrial trends or availability of data resources) from other parts of the community.

    European Open Data Portal

    This portal is about transparency, open government and innovation. The European Commission Data Portal provides access to open public data from the European Commission. It also provides access to data of other Union institutions, bodies, offices and agencies at their request. The published data can be downloaded by everyone interested to facilitate reuse, linking and the creation of innovative services. Moreover, this Data Portal promotes and builds literacy around Europe’s data. The data publishers, application developers and the general public can also use new functionalities enabled by the semantic technologies.

    NISO Publishes Themed Issue of Information Standards Quarterly on Linked Data for Libraries, Archives, and Museums - National Information Standards Organization

    Baltimore, MD - September 10, 2012 - The National Information Standards Organization (NISO) announces the publication of a special themed issue of the Information Standards Quarterly (ISQ) magazine on Linked Data for Libraries, Archives, and Museums. ISQ Guest Content Editor, Corey Harper, Metadata Services Librarian, New York University has pulled together a broad range of perspectives on what is happening today with linked data in cultural institutions. He states in his introductory letter, "As the Linked Data Web continues to expand, significant challenges remain around integrating such diverse data sources. As the variance of the data becomes increasingly clear, there is an emerging need for an infrastructure to manage the diverse vocabularie

    SPARQL 1.1: Proposed Recommendation

    El grupo W3C SPARQL Working Group ha publicado SPARQL 1.1 como Proposed Recommendation. Tras el exito de SPARQL 1.0, SPARQL 1.1 es un estándar complete para trabajar con datos RDF que incluye lenguaje de consulta y actualización, dos protocolos HTTP, resultados en tres formatos, y otras características explotandos los puntos SPARQL. La mayoría de las características de SPARQL 1.1 han sido ya implementadas por varios proveedores como muestra la siguiente tabla.

    The Proposed Recommendations are:

    1. SPARQL 1.1 Overview - Overview of SPARQL 1.1 and the SPARQL 1.1 documents
    2. SPARQL 1.1 Query Language - A query language for RDF data.
    3. SPARQL 1.1 Update - Specifies additions to the query language to allow clients to update stored data
    4. SPARQL 1.1 Query Results JSON Format - How to use JSON for SPARQL query results
    5. SPARQL 1.1 Query Results CSV and TSV Formats - How to use comma-separated values (CVS) and tab-separated values (TSV) for SPARQL query results
    6. SPARQL Query Results XML Format - How to use XML for SPARQL query results. (This contains only minor, editorial updates from SPARQL 1.0, and is actually a Proposed Edited Recommendation.)
    7. SPARQL 1.1 Federated Query - an extension of the SPARQL 1.1 Query Language for executing queries distributed over different SPARQL endpoints.
    8. SPARQL 1.1 Service Description - a method for discovering and a vocabulary for describing SPARQL services.

    The following are Candidate Recommendations, as the group still seeks more feedback from implementors:

    1. SPARQL 1.1 Entailment Regimes - defines the semantics of SPARQL queries under entailment regimes such as RDF Schema, OWL, or RIF.
    2. SPARQL 1.1 Protocol for RDF - A protocol defining means for conveying arbitrary SPARQL queries and update requests to a SPARQL service.
    3. SPARQL 1.1 Graph Store HTTP Protocol - As opposed to the full SPARQL protocol, this specification defines minimal means for managing RDF graph content directly via common HTTP operations.

    The group has also produced a test suite and a page on using SPARQL 1.1 with RDF 1.1.

    Opening up government: data.gov.uk

    El Gobierno de Reino unido ha publicado datos públicos para ayudar a los ciudadanos a entender cómo funciona el gobierno y las políticas que se llevan a cabo. Algunos de estos datos ya están disponibles en esta Web.

    Actualmente hay más de 5.400 conjuntos de datos disponibles, de todos los departamentos del gobierno central y de una serie de otros organismos del sector público y de autoridades locales. Estos datos pueden ser utilizados de distintas formas. Por ejemplo para analizar las tendencias en el tiempo de un área de política o para comparar cómo diferentes partes del gobierno hacen su trabajo. Los usuarios técnicos pueden usar estos datos para crear aplicaciones.

     El objetivo de hacer estos datos fácilmente disponibles es facilitar a las personas y organizaciones a tomar decisiones y sugerencias acerca de las políticas gubernamentales basadas en la información detallada.
