AST

Added Oml2VppVisitor both vpp and Java. (Other versions of the file will be removed later from the SVN)

StdLib

• Added VDMUtil both vpp and Java. (Java implementation is incomplete)
• Added IO both vpp and Java. (Java implementation is incomplete)

Umltrans

• Updated Vpp to Uml to report classes which cannot be transformed in the console
• Added print of transformed classes and total execution time
• Added unit test comparing both vpp files and xmi files from the transformation with expected files.

Tools (Maven build automation)

• Vdmt (1.0.3)
• New goal for creation of VDM Tools project
• Update to the code generator so it works with large number of classes and have build in check sum to insure that only changed classes are generated.
• New goal to generate a log file with the path to all files in the project.

Astgen

• Created a Maven plugin to wrap Marcels AstGen?
• Added a goal for generating the vpp files from a .ast file in a project

eclipse (Christian and David)

• No status reported

POTrans (Miguel)

Miguel has created a new subproject named Automatic Proof System (APS) (svn:core/proofsupport) where he implemented the basic interaction for the proof system as designed by Sander Vermolen.

• Action 36/4: Miguel to coordinate a demo of proof support by FM09

VDMJ (Nick)

Nick created a command line client for the DBGp protocol. Nick started the work on the VICE extension execution (previously it only did VICE type checking).

Test Automation Support (Carlos)

Carlos will take over this subject. Kenneth and Peter will help to get started both in terms of current work and future plans.

Overture Community Process

Note: Language Board = Executive Committee.

LB to be downsized to 5 members.

The LB accepted the first three proposals and they are:

• International character support for Overture identifiers
• The introduction of the “reverse” sequence operator
• Generalising let-be expressions

The proposals will pass through a stage of deliberation and then execution.

Language Boards Issues

Overture covering several VDM dialects instead of just OML?

Overture will undergo a series of changes to make it more linkable with the VDM “brand”. Dropping the OML name is one of the actions and avoiding the reference to different dialects might help with citations. Referring to it as VDM tools: Next Generation could also improve the visibility of Overture.

Overture will support different VDM dialects. LB is to decide which changes to the dialect will be supported but anybody is allowed to make any their own experiments/changes.
