Hi, Lately I've been working on another feature request from the Petaverse guys: rewrite the ClassServer so that it would be possible for third-parties to extend the type hierarchy (if anyone would like to try it, the code is available at lp:~gama/opencog/classserver; docs are available inside the opencog/atomspace/README file).
The code, documentation, examples and cmake integration are pretty much ready but there's one task left which is to trim the current 'atom types' hierarchy -- previously defined in the file 'type.script' which I'm pasting at the end of this message. I could take a stab and try to split and redistribute the current hierarchy into the proper modules based on intuition but it's likely that I would screw up and end up breaking things for others. Besides, there are plenty of types that I'm unsure whether they should be tied to the lower level libatomtable or some specific module (for instance, should WORD_NODE be tied to the nlp module? what about SHAPE_NODE? etc. etc.). So I've resorted to asking for everybody's help. :-) Module "owners" could perhaps list the types that they know they'll use exclusively; old-timers might know which types were added for a short-lived experiment or a demo; and those more familiar with the conceptual opencog model probably know which types will be shared by multiple modules/agents/applications. thanks, -- Gustavo --------------------------- 8< ----------------------------- // // Script for automatic Type generation // ATOM NODE <- ATOM LINK <- ATOM CONCEPT_NODE <- NODE WORD_NODE <- NODE NUMBER_NODE <- NODE SHAPE_NODE <- NODE POINT_NODE <- NODE // Basic Links ORDERED_LINK <- LINK UNORDERED_LINK <- LINK // Basic sets SET_LINK <- UNORDERED_LINK SUBSET_LINK <- ORDERED_LINK PART_OF_LINK <- ORDERED_LINK LIST_LINK <- ORDERED_LINK MEMBER_LINK <- ORDERED_LINK // Boolean Set operations and related ideas.
