XAIF ( = XML Abstract Interface Format) had a predecessor called AIF used in ADIFOR for the language independent representation of assignment statements. With the availability of parsing software for XML it was possible to switch to an XML based representation with schema validating parsers. Since the beginning of the ACTS projects there have been major extensions to the set of code information represented in XAIF, e.g.
The current version of XAIF is numbered 1.0. While the definition of the basic elements is stable the OpenAD algorithm specific extensions are under development. At this stage we do not reflect these changes with new version numbers. The respective latest version of XAIF can be found on the XAIF homepage.
