We made the Web accessible to human. We are making the web accessible to computers with Linked Open Data (LOD - https://www.w3.org/standards/semanticweb/data). More and more RDF data is created by people and institutions to contribute to the LOD. However, publishing this RDF data with content negotiation is rarely done, because there is no on-shelve solution. Moreover, there is no easy to use user interface to manage linked data (including CRUD operations, but also user permissions, rendering, etc.).

CubicWeb is a SCMS (Semantic Content Management System) for Linked Open Data (https://forge.extranet.logilab.fr/cubicweb/cubicweb). This python-based framework can be used to import OWL schema and RDF data automatically to generate a new CubicWeb instance. This instance can be used out-of-the-box as a single application to serve RDF data through a conventional web interface for browsing and through content negotiation for downloading. No need to configure anything, just import and launch the app. The CubicWeb framework implements an administration interface to manage data easily even for non-technical people. All the common features of a web application framework are available.

We made the Web accessible to human. What about making the web (of data) accessible to computers? Publish open data could be struggling. Deposit a CSV file on a web server is not enough. The data model used should be explicitly defined.

The Linked Open Data (https://www.w3.org/standards/semanticweb/data) solves this with: * standardized implementation format (RDF) * standardized data access (Content negociation, SPARQL endpoint) * standardized data indentification (URI, data model as data)

For example all the data from the Bibliothèque National de France (national library of France) are widely accessible by using these standards. This allowed the development of data federation initiatives, such as Europeana (https://www.europeana.eu).

CubicWeb is a semantic web application framework, licensed under the LGPL, that follows Linked Open Data best practices. During this presentation we will discuss about Linked Open Data benefits, and how CubicWeb could be used as a "on shelve" framework to do so.
