The OSCMS summit is now over, but it's been a great week, packed full of information and activities. I've met a number of the other people interested in using Drupal for location-enabled activities, from simply tagging of content with a geographic location, to mapping those locations (and others) and actually implementing more GIS-like functionality.
One of the things I really want to see happen (and will certainly be helping with) is making sure that we are complying to standards of geographic data sharing so that information from outside the Drupal framework can be pulled into Drupal, and information can similarly be pushed out and used by other systems - from Drupal sites (through GeoRSS feeds - or the other GeoRSS standard being proposed), to Google Earth (using KML) and also systems capable of reading in OGC-compliant feeds (probably implementing a WFS interface).
Improving the usability and functionality of inputting geographic information is also high on my priority list, trying to get away from the largely US-centric input that is present at the moment. Of course, that's not easy when the availability of reliable and open geographic data is scarce outside of the USA.
I'll be keeping track on here of the bits I'm working on - and others are working on - here in my blog over time.
