D2R Server ^[1]

Technologies

• Java

Short description

D2R Server allows the access to a non-RDF database using SPARQL, an RDF browser or a common HTML browser. A mapping between the database and the RDF classes and properties is provided by a mapping document.

Features detail

• Mapping documents use the D2RQ language ^[2] to map the database to RDF classes and properties
• Automatic creation of mapping document starting from a database, foreign key specifications are taken into consideration
• Mapping customization
• Creation of a SPQRQL endpoint and possibility to query the database using SPARQL
• Database RDF browsing through an RDF browser such as Tabulator ^[3], implementing dereferenciation
• Database browsing through an HTML browser
• RDF dump creation

SquirrelRDF ^[4]

Technologies

• Java

Short description

SquirrelRDF allows the access to a non-RDF database or an LDAP using SPARQL. A mapping between the database and the RDF classes and properties is provided by a mapping document.

Features detail

• Automatic creation of mapping document starting from a database, foreign key specifications are not taken into consideration
• Mapping customization
• SPAQRL access through command line or HTTP

DaDaBIK ^[14]

Technologies

• PHP
• Wordnet

Short description

DaDaBIK is a Web based software which allows to generate a Web front-end for a database. The DaDaBIK OWL module extracts an OWL ontology from a database.

Features detail

• OWL ontology (including individuals) generation from a DaDaBIK instance
• DaDaBIK metadata used to make the ontology generation more accurate (e.g. use of labels instead of attribute and table names, recognition of not expressed foreign key relations, use of Wordnet term relationships to recognize class hierarchy relationships, use of master-details view to recognize is part of relationships)
