Comunidade Áreas de Integração: Dados Conectados

From Google Translate: "The web that we know today is the web of documents, where HTML pages are made available, files of various formats, such as spreadsheets, text documents, maps, geographic coordinates, animations, multimedia content, etc. It turns out that the data, even if they are available in open formats, to be accessible first, it is necessary to find the file that stores the data, so, yes, to access each data, because most are unstructured formats and are suitable to facilitate the Access and reading for humans and are not understandable by machine [2].

Considering mundane situations like this, the World Wide Web Consortium - W3C has been working hard not only to establish global internet standards, but lately, to offer data on the Web, as we have already presented in the  previous post .

And how would it be if we could directly access the data available on the web, through queries to data servers? Queries that access data of diverse origins, spread throughout the world and still, obtaining not only the data but the semantics related to them. Looking to build this web of data that, among many other things, solve the common problems of the beginning of the article that, during these efforts and research developed by the W3C, Tim Berners-Lee (himself, the same guy who invented the Web) proposed A very promising concept that is the Connected Data of the English term, Linked Data  [3].

   For a given to be connected, it must obey the four principles for publication [4]:

1. Use URIs to define things;
2. Use HTTP URIs so that data can be found by human and web agents;
3. When a data is requested through HTTP URIs, provide all information about it, in a structured data format using standards such as RDF and SPARQL;
4. Include links to other related data sources (using URIs) so that you can get more information.

From the concept of Connected Data, some global nations are already considering this new paradigm and encouraging its production and supply. Countries such as the United Kingdom and the United States of America already have a good supply of data in RDF format in their government data catalogs. In addition, large projects on a global scale have grown every year, such as  DBPedia [5], which is the database connected from  Wikipedia  or  LODSpringer [6], which aims to provide connected data about articles, periodicals and conferences Published by Springer."
