Hi,
i think i would be really helpful for the mapping creators - me included :)
- if they could test custom wikipedia pages and not just the first 5-6 in
the list.
There is already a greasemonkey script for DBpedia from Anja Jentzsch (
http://wiki.dbpedia.org/DBpediaUserScript).
it could be easily modified to link to a custom mapping server page,
provided the server supports custom page extraction.
If the server supports it, you can send me the url and I will create the
script in order to be included it in the mapping Wiki.
Cheers,
Dimitris
