Visualize PAV provenance as SVG (2)

• Download

VoID descriptions are fetched as Turtle, cleaned up to be valid OWL ontology and include useful labels, processed through the OWL reasoner Pellet; this adds inferred PROV statements to the RDF, which is then fed to the PROV Toolbox, generating an SVG visualization of the provenance. Note that this workflow downloads CWM, Pellet and ProvToolbox on demand, and uses UNIX command line tools like wget and md5 which are unlikely to work in Windows. This workflow has been tested on Ubuntu 12.10 wit...

Voronoi polygon generation using GRASS-GIS... (1)

• Download

Generic example on how to deal with vectorial data. Major pitfall is the need to process ProcessOutputs using Xpath plugin. A random point file in GML 2.1.2 is sent to the v.voronoi service and after it is sent to a service that runs v.out.svg generating a SVG image that can be rendered in Taverna (need to set output to SVG image)
