This is an almost complete re-write of SEMOSS project from https://github.com/semoss. That project appears dormant, though it may simply have moved to SourceForge.

The toolkit is a GUI application to explore semantic databases. It includes almost all the functionality of the original tool, including:

• Multiple output styles (graphs, tables, charts)
• Lots of graph functionality
  • Island, loop identification
  • Customizable icons, colors, text
  • Arbitrary graph traversal
  • Distance downstream, upstream
  • Multiple layout options
  • Minimum spanning tree
• Custom chart generation
• SPARQL editor
• Perspective/Insight query concept

And Adds:

• An updated technology stack (Java 8, BlazeGraph 2.1, JUNG 2.1)
• Standardized GUI elements and behaviors
• Standardized RDF predicates and querying
• Graphical Query Builder -- generate SPARQL via a graphical interface
• Insight Manager -- pre-define and organize queries, output styles
• Unit testing
• Error handling
• Multi-threaded UI, engine code
• More graph functions
  • Export to table
  • Condense
  • Full-text indexing/search
  • Export Edge List
• Automatic database metamodel generation
• Convert table to graph and vice versa
• Syntax-highlighting

The source code is organized into several packages, and built with Maven.

• Parent -- The meta-package to kick everything off
  • Common -- Pieces of code that span multiple projects
  • GUI -- The main GUI application
  • Tools -- A collection of tools like a legacy database upgrader and embedded webserver
  • Web -- Not fully functional at the moment
