Basic MDA Pattern
ƒ Generic transformations
PIM
• Additional
information
• Model markup
– Implement best practices,
architectural and design
patterns, technology patterns
(e.g., J3EE patterns),
optimizations, etc.
ƒ Additional information
Transformation
– Adjust the transformation
globally
– Similar to compiler options
Generic
transformation
ƒ Model markup
– Direct the transformation of
particular model elements
– Not part of the PIM
– Different platform mappings
may require different markup
– Similar to compiler pragmas
PSM
OMG

Basic MDA Pattern
ƒ The basic pattern can be
applied multiple times
ƒ PIMs and PSMs are relative
notions
– “Someone’s PIM can be
someone else’s PSM”
ƒ Platform independence is
relative, too
– It’s a scoping issue
– It’s a strategic decision

OMG QVT Standard – Current status
– Objective of the QVT standard
• Define a language to express queries, views and transformations on models
– Maturity for the final standard
•

•
Initial submission (2003-03) : 8 submissions
Revised submission (2003-08): 5 submissions + Kennedy Carter in list
2nd revised submission (2004-01)
3rd revised submission (2005-01), QVT-Merge
– Major obstructions:
• Consortiums with different or opposite paradigms for model
transformation
• Current QVT requirements are not user driven, but more technically
oriented
– e.g. no requirement guarantees QVT code portability (e.g. for rule engines)
