	VDM Information: examples respository
		This specification is a transformation from an abstract syntax representation of a data flow diagram into an abstract syntax representation of a VDM specification.
		This is a formal semantics for the language in VDM-SL.
		This is a specification of a looseness analysis tool which given a specification written in a subset of VDM-SL can determine which values a given VDM expression (using the definitions) may evaluate to in the different models for the specification.

	VDM - Vienna Development Method
		VDM is their modern descendent, now used well beyond the bounds of language semantics in industrial systems development as well as academic research.
		VDM courses are available from Adelard: length of training courses vary from a one day overview, though an intensive 5 days, and as long as 2 to 3 weeks when clients want a significant case study of their choosing to be undertaken.
		VDM++ is supported by a toolset with a graphical user interface (VDM++ checkers, a code generator, facilities for pretty-printing), linked to a tool from which it is possible to (partially) generate a VDM++ specification from a graphical OMT model.

	Larch Frequently Asked Questions (comp.specification.larch FAQ)
		Framing for procedure specifications in VDM-SL is done by declaring external variables, and noting which are readable and writable by a procedure; these two classes of variables are respectively defined by external declarations (in LCL and Larch/C++), and by the modifies clause.
		At that time, they proposed a combination of algebraic and operational specifications which they referred to as "dyadic specification." Working with Wing, by 1980 they had evolved the essence of the two-tiered approach to specification; the term "two-tiered" was introduced by Wing in her dissertation [Wing83].
		A specification is useful as a contract between the implementor and a client of an abstraction (such as a procedure or a data type).

	JOT: Journal of Object Technology - Object Oriented Extension to Time Series Model
		We adopt a formal specification language, adapted from VDM [Jones 1986] and UML to accommodate the modelling of object-oriented concepts.
		This VDM-like language is used to develop a formalised model of how objects may be time-stamped in both the valid-time and transaction-time dimensions in a temporal database.
		It is relevant to note that VDM lacks a facility for associating the value of an object representing a real-world entity with a real-world time.

	High Assurance (for Security or Safety) and Free-Libre / Open Source Software (FLOSS)... with Lots on Formal Methods
		Jaza (GPL) is an "Animator" for the Z formal specification language, developed at the University of Waikato (primarily by Mark Utting).
		VDM seems to be less active than Z to me, but that is simply an impression and may not be true.
		In these languages it’s easy to redefine fundamental constructs (say, a library function) in the language, while the program is running, far away from their use or definition (aka “action at a distance”).

	Automatic Test Data Generation From VDM-SL Specifications
		Formal specification: The behaviour of each function, class etc. is specified in a quite abstract, mathematical way, mainly using predicate expressions.
		As before, the power of the specification language makes full automation of the test data generation very difficult, if not impossible, but at least for a subset of the language, such a tool can be written.
		The VDM Specification Language is described in a 1993 ISO draft.

		An ISO Standard for the language was released in 1996 (ISO, 1996).

		The purpose of the project is to translate VDM code into Haskell code integrating this functionality in the VooDooM project.
		For start the VooDooM frontend should be used which allows to read VDM specifications and create its Abstract Syntax Tree (in Haskell).

	Type inference and union types \| Lambda the Ultimate
		VDM++ is an object-oriented, formal specification language, typically used to model mission-critical systems.
		The syntax is mathematically oriented, using a lot of abstract constructs such as sets, sequences, maps and unions as well as more widespread language constructs.
		I am looking for some pointers to literature on the use of union types, specifically the problems which union types may cause in connection with type inference.

	MainFrame: RBJ's Work on The Foundations of Mathematics
		In 1985 I wrote a paper discussing this "work" for presentation at an "Appin Workshop on Persistent Databases" in which I took the position that knowlege representation languages must be logic and discuss the question of what kind of logic is suitable for that purpose.
		This didn't make any sense to me, the proof rules have to be proof rules for the specification language, otherwise there would be some translation involved which would be a source of error.
		Having argued that the VDM specification language should be amount to a mathematical foundation system, I felt that the proposed semantic domains would not be suitable for such a language, and set about devising more suitable domains.

	Larch Frequently Asked Questions (comp.specification.larch FAQ) FAQ
		By VDM, one means, of course, the specification language VDM-SL [Jones90] [Andrews-etal93].
		However, we do not use the term "Larch interface language" as a synonym for "BISL", because there are BISLs outside the Larch family (such as those in the RESOLVE family [Edwards-etal94]).
		It is part of the specification environment, Penelope, which also has a proof assistant and a tool, AdaWise, for checking the subset of Ada used in Penelope.

		To describe the structure of a language and to manipulate programs and program fragments in that language as basic data objects, the Absynt metaprogramming language has been designed.
		An important consequence is that we obtain a library of language definition modules.
		One level is related to the abstract-syntax-oriented way of describing language processing tools, resulting in a modularization of the programming language definition.

		The specification of facilities (and decisions about whether or not to include certain facilities, as suggested by the "shall support" definition in the previous section) which is written by the PCIS definers, and
		The implementation decisions about how certain facilities are provided (for example, if a PCIS implementor determines that it is feasible, the implementation may provide a particular specified PCIS facility by reusing other PCIS facilities, thereby achieving a "layered implementation" of the PCIS).
		Therefore, the realization of a specific PCIS implementation is the result of intentionally divided decision-making authority among this requirements document, the PCIS definers, and the PCIS implementors.

	Towards A Formal Semantics Of The BSI/VDM Specification Language. - Arentoft, Bear, Semantics, BSI, Language, ...
		Towards A Formal Semantics Of The BSI/VDM Specification Language.
		Abstract: This paper gives a technical/scientific survey of the mathematical semantics of the BSI/VDM Specification Language, currently being standardised by the British Standards Institution.
		Following a background introduction, the notion of loose (nondeterministic and underdetermined) specifications and the implications for the underlying type (domain) universe is discussed.

	Sample: The Formal Specification Language Z
		The Z (pronounced Zed) language is a formal specification language that makes it easier to write mathematical description of complex dynamic systems such as software.
		The descriptions are usually smaller and simpler than any programming language can provide.
		A minor problem with the spread of Z is that it is designed as language to be written rather than as a language to be input into a computer.
