Visual Strategies for RDF

Concepts

• COLD 2013 paper: Content-preserving Graphics
• Semantic User Interfaces / Pixel metadata

Tasks and techniques:

• Characterizing a list of RDF node URIs - what to do if all you have is a list of URIs.
• SPO Balance - Creating RDF graph glyphs using topologically-based resource and predicate partitioning.
• Centrifuge - Minimum spanning tree and graph embedding by incrementally deleting connected components' delegates.
• Rooted path finding - I have two nodes in an RDF graph, what's in between?
• TiNG Triples in Named Graph - Looking at graph overlaps.

Rubber, meet road:

• Installing VSR
• Simple visual strategies are created by placing the RDF input graph's classes and properties into one of 26 groups.
• Implementing a new visual strategy: vsr2.xsl
• Provenance capture
• Implementing a new target graphical format: 2grph.xsl
• Recovering Data from View
• Content augmentation
• Deriving a VoID Linkset view of an SPO Balance

Dependencies:

• XSLTdoc
• Invoking Java from XSLT using saxonb9 1 0 8j
• Invoking Saxon from Java
• Tinkerpop
