Hi Joel, Hi Misgana Thanks for answering.

If you just want to track positions of things, I believe that ROS has some kick-butt solutions for that: I mean -- people are building self-driving, self-flying you-name-its with ROS and you are not going to beat the sensory infrastructure that has been built up there. My primary interest is to hook up perception to language and spatial reasoning. For that, one has to be able to access spatial data on the same platform that is doing language -- so, in my case, the AtomSpace. For language and common-sense reasoning, that means prepositions: is it above? below? bigger? smaller? etc. so I am pushing for that. (I really really want to be able to say "here, this is opencog actually doing something useful", and talking about perception would be that.) But if you want to do, -- I dunno -- spatial reasoning, well, wow, that would be a completely different thing, that would be pure AI research, as far as I'm concerned ... but also more-or-less unrelated to opencog... I'm not sure what advantage you'd get from using the atomspace, or other parts of opencog, as opposed to starting with a blank slate. > > Even being part of Slack, > I keep asking for Matrix.

Well, forever. I don't know why. I don't have the personality to go around and poll everyone about what they are doing.

I rejected your (Misgana's) last pull request, because it was a re-invention of the code you had written earlier... and your earlier code was already merged (and actually, it worked better) I'm not sure how close that version is to your conceptual design, but I > want to avoid writing YASTS (Yet Another Space Time Server) or duplicating > work already done. > I think the wiki page spells out everything that has and has not been done. > > Once I'm more sure about my priorities I'll have a better idea if I can > dedicate time to building/improving the SpaceTime server as you see it. > Well, that would be cool. I think that what I wrote in the wiki page consists of bite-size, achievable steps that would be a good warmup for getting back into opencog.
