Hi all, today I added a useful new prefix class to the database stuff:
+UT This is a prefix class for '+Aux', extending it so that it combines the multiple attributes into a single multi-dimensional key. This allows access to ranges of values (as opposed to a plain +Aux, which gives you access to explicit combinations of multiple keys, but not to an rectangle, box, etc. as a confined region). Typical examples would be geographic coordinates (2 dimensions) or GPS data (3 dimensions). BTW, I felt that I should finally try Twitter! So I created an account a few days ago, and just now I twittered (tweeted, twote?) the good news about the UB-Tree into the world :D @Henrik: You are the first (and only one so far) I'm following ;-) Anybody else?
