The "Blackboard" architecture appeared in the mid 1970's as a way for software agents to cooperate on problems not fully understood at creation time. A retrospective paper is The Evolution of Blackboard Control Architectures (1992, Norman Carver, Victor Lesser). There's an out-of-print book Blackboard Systems, by Robert Engelmore, Tony Morgan, eds, Addison-Wesley 1988, ISBN:0201174316.
This model seems to work well for the Semantic Web,
where the uncertainty of problem structuring is even greater, since the
problem is completely unspecified. What this means for the Semantic Web is
that programs should funnel their communications through an API like
tell(string, string, string). Queries become
first-class objects to be passed across this interface.
