Welcome to the SIM-TBASSCO Project home page.

SIM-TBASSCO (Semantic Interoperability Measures: Template-Based Assurance of Semantic interoperability in Software COmposition) addresses a critical problem in the longstanding software engineering goal of assembling software from components: adaptive composition sensitive to quality concerns. Conventional approaches support composition up to a point, but cannot handle qualitative considerations in composition, such as implementation effort, performance, resource requirements, or reliability. SIM-TBASSCO helps software developers engage in guided, efficient searches and evaluations of the set of alternative system implementations that can be built with the components available to them. It will let developers evaluate components' functional and data equivalence compatibility, find pertinent data conversion mappings, and predict performance (time, space, network) of a component architecture under specific usage situations and hardware/networking environments.

"When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the state of Science, whatever the matter may be."
--- Lord Kelvin
