Package: Fenfire Loom
System name: loom
Type: non-GNU

Description:
Fenfire Loom is going to be a focus+context editor for the W3C Resource 
Description Framework (RDF, http://www.w3.org/RDF). This means that there is, 
at any time, a *focused* RDF node which is shown in the middle of the screen; 
the nodes directly connected to the focused node are shown around it. The 
result is that the graph is shown in a much cleaner way than with a 
two-dimensional layout of all nodes in the graph; even with a good layouter, 
this can result in a lot of complicated scrolling.

Additionally, Loom is able to show only a subset of a graph, by turning 
individual properties on and off; properties which are turned off are simply 
not shown. In the future, Loom will support building view profiles, in the 
simplest case collections of properties which can be turned on and off 
together. This is essential for extracting information from a graph, because it 
allows connections irrelevant to the task at hand to be hidden (for example, 
rdf:type connections, which give the class of an RDF node).

Loom is part of the Fenfire project <http://www.nongnu.org/fenfire>, but usable 
independently of it. We want to make it more accessible to people as an RDF 
browser and editor, outside the context of the Fenfire project.

Currently, Loom can only browse, not edit an RDF graph; we\'re going to  add 
edit capabilities in the next release (when we\'ve fixed Kaffe to run it, see 
below). The current code can be found in the Fenfire CVS 
(<http://subversions.gnu.org/cgi-bin/viewcvs/fenfire/fenfire/>), in the 
subdirectories org/fenfire/loom and org/fenfire/util.

Other Software Required:
Fenfire Loom is written in Java. It is intended to run on Kaffe. Currently 
there is a bug in the CVS version of Kaffe that prevents the current version of 
Loom to run on it; we\'ve reported this bug and are currently waiting for the 
Kaffe developers to fix it. -- Unfortunately, there are a number of bugs in the 
last released version of Kaffe which prevent Loom to run on it. Before the next 
release of Kaffe, we will have to ask users to compile Kaffe themselves.

Loom also depends on Libvob <http://savannah.nongnu.org/projects/libvob/> and 
Jena <http://www.hpl.hp.com/semweb/jena.htm>.
