Hello,

we're happy to announce VisiNav, a data search and navigation tool we've 
been using for a while now to navigate and debug web data.

The data (currently around 10m RDF triples) has been collected from the 
web and doesn't follow a fixed schema.  On a conceptual level, VisiNav 
deals with objects that have attributes and links to other objects.  For 
example, there are objects of type Person; a Person has a name; a Person 
knows another Person; a Person makes Documents.

The system allows for searching, teleporting to objects, facated 
browsing, and set-based link navigation.  We have formally specified the 
search and navigation operations but that's probably best explained in a 
technical report.

You can use the site to visualise query results in a table, graph, map, 
or timeline view.  For example, with a few clicks you can display a map 
with the locations of people described in the dataset [2], or show in a 
timeline view the things made by people who are interested in RDF [3].

In summary, the system demonstrates how to combine data from multiple 
sources into a single unified view, how to search and navigate the 
aggregated dataset, and how to re-use query results from web data in 
external applications.

Happy exploring!

Regards,
Andreas.
