"the repective metamodel?"
Andreas Leue commented on Model Practice's blog post Note on Languages and Abstraction
"Yes, for a given language, that should hold: metamodel M3 (M2, M1) is typically more neutral than corresponding models M2 (M1, M0), otherwise the design of the repective metamodel is to be questioned.

"Thank Andreas for expounding!
I think I got some more understandings to your 'neutral'...
It's perhaps can be said that, a meta-model is usually more neutral, even complete neutral..."
Andreas Leue commented on Model Practice's blog post Note on Languages and Abstraction
"As for neutrality one can distinguish different abstractions; on the domain side there is
- independence of the model from some domain aspects (like e.g. finding commonalities between businesses)
- independence of the meta model from domains (going…"

"I can't make a clear conclusion to the 'neutral' yet.
Perhaps we might well talk about 'models' instead of the 'abstractions'.
There are two models from two objects (the source the model be abstracted from): the…"

"Hi TY
"... they have different own source or basis to abstract"
so, do different abstraction types make it generally impossible to determine a reasonable >most< neutral position?

"I think the key point is two ways, IMHO, they have different own source or basis to abstract.. (some related discussions on my blog at here)"

"Abstraction only goes one way - upwards.

Model Practice commented on Model Practice's blog post Note on Languages and Abstraction
"Hi altogether
think the "most neutral position" expression is one that I'm going to adopt, where I find the "most" (what makes it an optimisation problem) is a really challenging bit.
Have fun

"Hi! |=, Andreas.
I Agree, too.
I have been writing an essay “Abstraction (III)” to be going to relate to this topic but haven’t been completed. :-p
I think, it's often be overlooked or confused in much practice and discussion,…"
Andreas Leue commented on Model Practice's blog post Note on Languages and Abstraction
"Hi Model Practice,
I agree. My favorite metaphor for this is the "bridge of abstraction, leading over the river of complexity": on the left side is Domain Land, on the right side Machine Land, on both side it's detailed &…"

Note on Languages and Abstraction
Just a short note.Programming languages do a 2-way abstraction:1. from machine level 'upwards', leaving out the technical bits.2. from (all addressed) problem domains 'downwards', promising that the language constructs provided correspond to the most important real world structures. In discussions on programming and abstraction, the latter seems a bit underrepresented, although not less important. That's why I just wanted to mention it here briefly.|=See More
Model Practice replied to Mountriver TY Yu's discussion The Mathematical Foundations for Models
"perhaps it's his way to capture the notion of direction, descriptively?
i.e. that S is in some way 'generated' from M?
perhaps, but can't say either.

TOOLS Europe 2011
Attended Tools Conferences last week, here my brief take-away (from an Analyst's point of view):
ICMT 2011:
Such a more technically influenced subject like M2M Tranformations can contain lots of inspiring single issues, even for an analyst doing more sort of World 2 Model Transformations. Issues like generalisation of generalisation, query/ modeling by example, ...
TOOLS 2011:
1. Is Subjectivity an approach to clarifying "Appliance" of…
