Re: [Semediawiki-user] Graph Data Structure Extension

[Markus <ma...@ai...>]

Hey Gregory,

that is indeed interesting news! Glad to hear that Case Western can use som=
e=20
of my current work -- I have been doing part of my own MSc there! :-)

I also had a look at your graph extension. I was wondering what to do with =
the=20
returned graph. It has spacial coordinates, so could it be plotted somehow?=
=20
In principle, it would also be possible to extract a similar graph from the=
=20
RDF export (which already is a different representation of a very similar=20
graph). RDF export can be recursive and inlcude backlinks, so you could=20
obtain a reasonable "surrounding" of some article. On the one hand, this=20
restricts you to the display of typed links, but on the other hand you woul=
d=20
also get a useful relation for each link and find additional attributes of=
=20
each node.

It might indeed be interesting to use RDF as an (alternative) output format=
,=20
because there are tools for displaying RDF graphs, and one could even hack=
=20
one to use geographical positions as a guideline for layout.

The Python Geo-API is also cool. Denny, our main Python hacker, is also qui=
te=20
delighted :-) You mentioned that you did not use the Geographic Coordinate=
=20
support from SMW in CASE-wiki since it contained some bugs. What are these?=
=20
It should accept at least those inputs that the mapsources extension can=20
take, and it provides some additional direct links to online maps (which ca=
n=20
be configured easily through the code).

Best regards,

Markus
