Hi SMW fans,
I am wondering if there is an alternative to the Semantic Result Format
"Process" (http://www.semantic-mediawiki.org/wiki/Help:Process_format) to
display data as process diagram. The same for the "Graphs" format.
Both formats need the GraphViz extension and an additional piece of software
running on the server (graphviz, mscgen). The extension itself is still in
beta and maintenance is unclear. Adding additional software to the server is
IMHO not a good choice (more load, more complexity).
So, what about a format that creates such graphs and diagrams using a
Are there any plans for letting the browser rendering the graphs instead of
the server? This would really, really be very welcome!
BTW: Does anybody know how EXACTLY the GraphViz extension creates the graphs?
Are they created every time on-the-fly if the wiki page is loaded? Or even
without touching the page (in the background). Are the images cached (as SVG
or PNG) - like regular image thumbnails are stored on the server? How about
performance impact on a wiki with many of these graphs?
Thanks and Best Regards
SRF Process is indeed a little bit tricky to get it up and running.
That's the reason why we created a "ready to use" package for enterprise
I think the complex configuration (and thus tons of questions from
users) is the main issue, why this format is looking for someone
maintaining it for such a long time.
In our config, SRF Process works as follows:
- Every time a page is loaded, prepare Graphviz code
- Pass Graphviz code to Graphviz
- Save created Image with unique timestamp (to avoid caching issues)
- garbage collection
This is not the perfect solution but works very well, no performance
issues so far.
