An integration domain is defined in Stephen Kell’s 2009 paper The Mythical Matched Modules as a domain where
- languages and tools are specialised towards composition of software, and so do not resemble conventional languages
- relations are expressed between runtime values, predicated on the context in which they occur
In addition through Stephen’s principle of interface hiding, dependencies do not explicitly manifest themselves in the domain except through the contextualised values which the domain puts into relation.
A core goal of the rewrite to version 6 of framework I have been working on, Infusion, is for it to host a software substrate representing an integration domain.
