graphl-interest — Low-traffic list for Graphl news and updates

[Flo L. <led...@im...>]

hi all,

today i released version 0.0.2 of graphl, the hybrid graph visualization 
toolkit, just before i will leave for 3 weeks of vacation in portugal 
tomorrow.

This is another pre-alpha release, to make new features available
before my vacation. Originally, i planned to do a 0.1 and some broader 
dissemination to the rdf community in august, but there are some
important features still missing and no testing was done at all - so i
decided to do another pre-release to just get the features out to those
who are interested and are willing to work with really unfinished, buggy
and undocumented stuff. probably this release is not very well-suited 
for pure end-users and rdf-focussed people, those should wait for the 
0.1 release to get a consistent package that will hopefully also be 
documented.

the most notable new feature is the possibility to configure the
rendering of graphs (by configuring and assigning "facets") in an
rdf configuration file. this should evolve into an "rdf-stylesheet" 
mechanism in the future. at the moment, there is no documentation
for all this, but you can look at the file config/config.rdf and see
if you figure out how to change the facet settings there.

for other improvements, see the changelog.

i will post a notification to this list when 0.1 is out - i hope this 
will happen late october. the most notable improvements i am planning 
for the 0.1 release are:

- finish and debug "load facet config from file" feature
- fully implement existing layouters and painters + make them fully 
rdf-config compatible
- extend ImageNodePainter to be able to render arbitrary properties as 
node icons (+ a fallback node painter if image is not found)
- SortedNodeLayouter sorts on arbitrary proprties by string, number or 
date, ordered or proportional (timeline!)
- testing with real-life rdf-files (foaf, ...?) and set default config 
accordingly (to get nice results on real-world data)

some things that might also happen for 0.1, but without guarantee:

- vocabulary registration per rdf-config (read in rdfs schemas and use 
them for contextmenus etc.)
- render edges as containership
- node layouter for geographic positioning (with map image as background)


btw: i you are interested in contributing to any of these features, or 
have requests for other features, help is greatly appreciated. mail me 
for coordination, or just start hacking and send me your patches...

all the best and have a nice late-summer,

f/0
