The GeoKnow Generator Workbench v1.1.0 Release Announcement

To demonstrate GeoKnow software tools we are developing a Workbench that integrates different components to support users in the tasks of generating Linked data out of spatial data. Several tools can be used for transforming, authoring, interlinking and visualising spatial data as linked data. In this post we want to introduce the public release of the GeoKnow Generator Workbench which implements most of the user requirements collected at the beginning of the project and integrates Virtuoso, Limes, TripleGeo, GeoLift, FAGI-gis, Mappify, Facete and Sparqlify.

The Workbench also provides Single Sign On functionality, user and role management and data access control for the different users. The Workbench is comprised of a front-end and back-end implementations. The front-end provides GUIs for software components where a REST API is available (LimesService, GeoLiftService and TripleGeoService). Components that provide their own GUI, are integrated using containers (FAGI-gis, OntoWiki, Mappify, Sparqlify and Virtuoso SPARQL query interface). The front-end also provides GUIs for the administrative features like users and roles management, data source management and graphs management, as well as the Dashboard GUI. The Dashboard provides a visual feedback to the user with the registered jobs and the status of executions. The Workbench back-end provides REST interfaces for management of users, roles, graphs, datasources and batch jobs, for retrieving the system configuration, and for importing RDF data. All system information is stored in Virtuoso RDF store.
