The Politics of Vocabulary Control Musings on schema.org and Linked Open Data http://www.academia.edu/12364988/The_Politics_of_Vocabulary_Control_Musings_on_schema.org_and_Linked_Open

Veille pour SemanticHPST:Technologies du web sémantique (des outils).

Le blog de Thomas Francart - “Data artisanat” : semantic web, open data, linked data, big data… et le Sparna Lab avec tout plein de choses autour de SKOS, SPARQL, Schema.org, DBPedia …

Quelques entreprises françaises: Antidot, Atos, Exalead, Logilab, Mondeca, Pearltrees, Semsoft, Temis

L’INSEE publie ainsi des versions sémantiques du Code Officiel Géographique (COG) qui recense les subdivisions administratives du territoire ou les données du recensement de la population. Etalab a aussi réalisé, avec le concours de la Direction de l’Information Légale et Administrative (DILA), un référentiel sémantique des administrations de l’Etat.

Ontologies

http://schema.org - Schema.org is a collaborative, community activity with a mission to create, maintain, and promote schemas for structured data on the Internet, on web pages, in email messages, and beyond. Schema.org is a collection of schemas that webmasters can use to markup HTML pages in ways recognized by major search providers, and that can also be used for structured data interoperability

Linked Open Vocabularies (LOV)

vocab.org - A URI space for vocabularies (http://purl.org/vocab/)

RDF4J

RDF4J (OpenRDF, Sesame) is a powerful Java framework for processing and handling RDF data. This includes creating, parsing, storing, inferencing and querying over such data. It offers an easy-to-use API that can be connected to all leading RDF storage solutions. For querying and analyzing RDF data. It contains a triplestore. As of May 2013, Sesame is ranked highest in the DB-Engines Ranking of RDF Stores. Sesame supports two query languages: SeRQL and SPARQL. Another component of Sesame is Alibaba, an API that allows for mapping Java classes onto ontologies and for generating Java source files from ontologies. This makes it possible to use specific ontologies like RSS, FOAF and the Dublin Core directly from Java. Free text search capabilities can be added through the LuceneSail.

Apache Marmotta

Apache Marmotta is an Open Platform for Linked Data. Read-Write Linked Data server, RDF triple store with transactions, versioning and rule-base reasoning, LDP, SPARQL and LDPath query, Transparent Linked Data Caching, Integrated basic security mechanisms. Marmotta comes as a continuation of the work in the Linked Media Framework project

GeoSPARQL

Geospatial (GeoSPARQL) and free text search can be added through uSeekM. more...

Interface humaine

Semantic MediaWiki (SMW) is a free, open-source extension to MediaWiki – the wiki software that powers Wikipedia – that lets you store and query data within the wiki's pages. Semantic MediaWiki is also a full-fledged framework, in conjunction with many spinoff extensions, that can turn a wiki into a powerful and flexible “collaborative database”. All data created within SMW can easily be published via the Semantic Web, allowing other systems to use this data seamlessly.
