    Generar RDF desde datos tabulares en la Web. Recomendación del W3C

    El documento define los procedimientos y reglas a aplicar para convertir datos tabulares en RDF. Los datos tabulares pueden estar complementados con anotaciones en metadatos que describan su estructura, el significado de su contenido, y si forma parte de una una colección de datos tabulares interrelacionados. El documento especifica el efecto de estos metadatos en el RDF resultante.

    Esta recomendación forma parte de un conjunto de documentos del W3C sobre CSV en la Web:

    Nuevas especificaciones para CSV ON THE WEB. Candidate Recommendation stage. W3C

    CSV (Comma Separated Values) es un formato antiguo, pero muy usado, de intercambio y publicación de datos en formato tabular. En el Grupo de Trabajo CSV on the Web, del W3C, se le está proporcionando una nueva vida, convirtiéndolo en un estándar Web de publicación de datos, incluyendo la declaración de formatos.

    La propuesta de estándar consta de estos 4 documentos: 

    Estos documentos toman CSV como su caso de uso, pero podrían aplicarse a cualquier otro formato tabular de datos compartidos (por ejemplo, TSV, Tab Separated Values). Se espera terminar la especificación a finales de octubre de 2015.

    Especialmente interesante resulta, en el ámbito de la Web Semántica y Linked Data, la especificación para convertir las filas de una tabla en triples RDF, mediante el uso de plantillas.

    Three Linked Data Vocabularies are W3C Recommendations

    • The Data Catalog (DCAT) Vocabulary is used to provide information about available data sources. When data sources are described using DCAT, it becomes much easier to create high-quality integrated and customized catalogs including entries from many different providers. Many national data portals are already using DCAT.
    • The Data Cube Vocabulary brings the cube model underlying SDMX (Statistical Data and Metadata eXchange, a popular ISO standard) to Linked Data. This vocabulary enables statistical and other regular data, such as measurements, to be published and then integrated and analyzed with RDF-based tools.
    • The Organization Ontology provides a powerful and flexible vocabulary for expressing the official relationships and roles within an organization. This allows for interoperation of personnel tools and will support emerging socially-aware software.

    Shakespeare’s works as Linked Data

    Proyecto que pretende convertir la obra de William Shakespeare en Linked Data:

    "I decided to take the XML encodings of Shakespeare’s works (all the plays and some verse works) which were provided in the Will’s World Registry, and see if they could be expressed as Linked Data. The intention is to provide a set of stable URLs which represent every aspect of the plays’ text, and which can be used as the basis for a shared understanding of this resource.  This is not really a hack in the usual sense, in that there isn’t very much to see when you have finished.  The value of the exercise will only become apparent, as and when other people start using the URLs which have been published".

    La 'materia prima' de la propuesta procede de Will's World Registry, "that provides a registry of Shakespeare related resources and services, and searchable metadata aggregated from those resource".

    Linked Heritage

    tipo de documento Página Web

    Linked Heritage

    The main goals of Linked Heritage are to contribute large quantities of new content to Europeana, from both the public and private sectors; to demonstrate enhancement of quality of content, in terms of metadata richness, re-use potential and uniqueness; to demonstrate enable improved search, retrieval and use of Europeana content.

    The consortium includes representatives of all the key stakeholder groups from 20 EU countries, together
    with Israel and Russia. These include ministries and responsible government agencies, content providers and
    aggregators, leading research centres, publishers and SMEs.

    Linked Open Data in Libraries, Archives and Museums Summit 2013 #LODLAM

    LODLAM es un evento internacional sobre la aplicación de la filosofía Linked Open Data en bibliotecas, archivos y museos:

    The International Linked Open Data in Libraries, Archives, and Museums Summit (LODLAM Summit) will convene leaders in their respective areas of expertise from the humanities and sciences to catalyze practical, actionable approaches to publishing and consuming Linked Open Data, specifically:

    • Identify the tools and techniques for publishing and working with Linked Open Data.
    • Share, consider and publicize precedents and policy for licensing and copyright considerations regarding the publishing of library, archive, and museum metadata.
    • Share and promote use cases that will give LAM staff the tools they need to begin implementing Linked Open Data in their institutions.

     

    The LODLAM Summit will take place June 19-20, 2013 in Montreal, Canada

    A Survey of Semantic Web Technology in the Oil and Gas Industry

    This W3C Use Case present some significant applications of Semantic Web technology in the oil and gas industry, and describe  how the industry can leverage this technology.

    Ontology-driven information integration and delivery leverage rich extensible domain ontologies found in the oil & gas industry, and combine them with industry standard definitions and controlled vocabularies. This results in meaningful metadata that reflects the concepts relevant to the domain. This approach is extensible, as different domain ontologies can be linked together via common elements. As this approach is not hierarchical, there isn’t a single root. This means that new data and ontologies can be integrated with much flexibility, and the solution can grow incrementally. It also makes it easy to reuse elements of the repository in other contexts.

    La red mEducator utiliza la tecnología semántica y los datos enlazados para ofrecer un servicio que permite acceder, evolucionar y reutilizar recursos educativos médicos en entornos de Educación Superior en Europa:

    "The mEducator Best Practice Network (BPN) aims to implement and critically evaluate existing standards and reference models in the field of e-learning in order to enable specialized state-of-the-art medical educational content to be discovered, retrieved, shared and re-used across European higher academic institution".

    mEducator ofrece su dataset en The Data Hub.

    El recurso incluye la descripción de uso de la tecnología semántica en el proyecto :

     

    "With sharing and reusing, educational resources become increasingly important for enhancing learning and teaching  experiences, particularly in medical educational domain since these resources are expensive to re-produce. In respect to this, many  efforts have been applied to federate the resources to achieve the sharing and reusing goals, which led to a fragmented landscape of  competing metadata schemas, such as IEEE LOM or OAI-DC, and interface mechanisms, such as OAI-PMH or SQI. However, the  major issue of educational resource federating is the heterogeneity challenge of metadata and data. In this paper, we illustrate a  medical educational dataset (mEducator Linked Educational Resources dataset) that is published as part of the Linked Open Data  cloud following Linked Data principles. The dataset contains educational resource metadata federated from ten different (medical)  educational institutes together with enriched links to related information by using Linked Data techniques and datasets. We introduce a Semantic Web Service based data extracting mechanism that is exploited for services and data integration to address  heterogeneous metadata problems. The paper also discusses the dataset accessing APIs, statistics and existing applications of using  the mEducator dataset".
