John. There was a Dagstuhl meeting back in ?2004 at which there were people working on FCA and also on Chu spaces, domains etc.(I think the reference was Spatial Representation: Discrete vs. Continuous Computational Models, Dagstuhl Seminar Proceedings (04351)). The conclusion of some of the participants (and I was one) was FCA and Domain theory were closely linked and the Concept lattices were the same as Chu spaces. I added some work on finite spaces and Chu ideas. This relates to the observation of spatial phenomena and hence to their representation and manipulation via AI type systems.
