This volume gives a coherent presentation of the outcome of
the project PROSPECTRA (PROgram development by SPECification
and TRAnsformation) that aims to provide a rigorous
methodology for developing correct software and a
comprehensive support system. The results are substantial: a
theoretically well-founded methodology covering the whole
development cycle, a very high-level specification and
transformation language family allowing meta-program
development and formalization of the development process
itself, and a prototype development system supporting
structure editing, incremental static-semantic checking,
interactive context-sensitivetransformation and
verification, development of transformation (meta-)
programs, version management, and so on, with an initial
libraryof specifications and a sizeable collection of
implemented transformations. The intended audience for this
documentation is the academic community working in this and
related areas and those members of the industrial community
interested in the use of formal methods.
