    Linked Data at the Guardian | Open Platform | The Guardian

    The semantic web is given a rough raking by the syntactic web, and it is not impossible to see why when you first get taken down the SPARQL/RDF/Ontology rabbit hole. It is not great fun learning to develop with the semantic web today.

    (As an aside, using a semi-SQL model as a primary metaphor in SPARQL did not help me personally. But then, SQL has always seemed like an assembly language designed by Prolog programmers)

    There’s Money in Linked Data

    Summary:

    To develop technologies, we need critical questions, and of course the most critical ones always come from the inside of a community or movement. But time has come to spread the good news for the ‘outside’.I believe that so far ‘linked data’ has always been perceived by people from outside the linked data core-community only as a new way to organize data on the web, thus technologies are still not mature for enterprises.Yes, databases which rely on linked data standards have become mature and enough performing for many query types so that they outperform even ‘traditional’ relational databases

    Why?

    • Yes, also issues which are critical for enterprise usage like privacy and security have been solved by most linked data technology vendors
    • Yes, there is a critical mass of available LOD sources (for example UK Ordnance Survey) and also of high-quality thesauri and ontologies (for example Wolter Kluwer’s working law thesaurus) to be reused in corporate settings
    • Yes, there is a volume of developers and consultants on the labor market (in the U.S. as well as in the E.U.) which is big enough to being able to execute large linked data projects
    • Yes, there are tons of business cases that can benefit from linked data. Linked data and semantic web technologies should be considered as core technologies for any information architecture, at least in larger corporations
    • Yes, SPARQL Query Language is not only a second SQL but comes with some brilliant features like transitive queries which help to save a lot of time when developing applications like business intelligence reporting and analysis
    • Yes, Linked Data has the potential to become the basis for a large variety of tools which help decision-makers (not only in enterprises but also in politics) to become true ‘digerati’ instead of being degraded to masters of the ‘bullshit bingo’.

    RDF Pro: Complete Semantic Web Tools Suite

    RDF Pro es una herramienta clave para trabajadores de la Web semántica que permite cargar modelos RDF ya sea de sus propios archivos, o desde la Web y visualizar, editar y en cualquiera de los formatos conocidos de la Web semántica. Entre sus características destacamos:

    • Edición de modelos.
    • Edición de triples básico.
    • Ontología de navegación y edición: las instancias, las clases y propiedades.
    • Conversión desde formatos SQL y CSV
    • Descubrimiento semántico
    • Exportar resultados en RDF.

    Next Generation Databases mostly address some of the points: being non-relational, distributed, open-source and horizontal scalable. The original intention has been modern web-scale databases. The movement began early 2009 and is growing rapidly. Often more characteristics apply as: schema-free, replication support, easy API, eventually consistency, and more. So the misleading term "nosql" (the community now translates it mostly with "not only sql") should be seen as an alias to something like the definition above.

    La comunidad de NoSQL, un grupo de personas que comparten la idea de destronar la tiranía de las bases de datos relaciones lentas, costosas y lentas, en favor de una alternativa mucho más eficiente y barata para manipular datos.
