....our understanding of precise requirements will evolve greatly, technology to support our goals will improve dramatically, and we will certainly make our share of poor choices in design and implementation. We share the methodology of the Domain Specific Systems Architecture (DSSA) community [Huff94] in recognizing the importance of modeling explicitly the domain s potentially significant entities and their possible interactions. The resulting ontology will provide a terminology within which the GA reference architecture(s) can be defined, and will give a set of shared concepts for ....

....entering into the domain. In principle, any of these entities and their associated GA processes (if any) may communicate with any other, but we expect the communication to be direct in only a few important cases that may change as the technology evolves. Special Functionalities The DSSA concept [Huff94] is most easily applicable to domains with existing limited systems, and provides a methodology for modularizing and generalizing these systems to facilitate future reuse of components in constructing new or variant applications in the same domain. In the GA domain, however, there is no existing ....
