"A detailed evaluation proved the benefits of the DSM solution: an increase of at least 750% in developer productivity, and greatly improved quality in the code and development process," writes Juha Kärnä from Polar.

"The quality of the generated code is clearly better, simply because the modeling language was designed to fit our terminal architecture. This rules out errors, eliminating them already in the design stage," says Antti Raunio from EADS.

"MetaEdit+ has eliminated our need to outsource software development activities," says Akihito Iwai, Chief Engineer, Denso.

"It's now easy to make modifications when the AUTOSAR version is changed — implementation and testing requirements are both reduced," says Yohsuke Satoh, Engineer, Denso.

"Even as a beginner with MetaEdit+, I could define a domain-specific activity language in about six hours - design, testing and one failed trial included," says Laurent Safa, Panasonic.

"Modeling with MetaEdit+ was indeed quite convenient and a lot easier to accomplish than trying to achieve the same results with Eclipse GMF," Ulf Hesselbarth, Siemens.

"MetaEdit+ is the most sophisticated DSM tool," writes Scott Ambler, Agile modeling expert

"MetaEdit+ is by far the most advanced tool in the graphical DSL category," writes Markus Völter, Author of Model-Driven Software Development (2006)

"a more mature example of [DSL tooling] is MetaEdit+ from MetaCase... MetaCase's approach makes building DSMs easy..., fast and cheap: typical developments to implement domain-specific modelling languages and code generators take less than 7 man-days". Abstractions in MDD

"The use of domain-specific languages and custom meta models is the greatest aid to productivity and making model-driven development a viable practice. Unfortunately, most vendors ship general-purpose UML modeling tools that are not easily customized to reflect domain-specific notations and constructs."

"The advantage of a DSL is that by letting designers focus on higher-level abstractions that are specific to the domain, we can be more productive than with a general-purpose modeling language. Furthermore, experts in the domain incorporate their knowledge into the DSL abstractions so that each designer does not have to figure them out for themselves. Domain-specific modeling takes DSLs a step further to provide a modeling framework that implements, supports, and automates the DSL."

Research at the University of Leipzig "compared six meta-metamodels that are using the metamodeling approach and are available as tools". "We conclude that GOPPRR and GME are the most powerfully expressive meta-metamodels". We can derive the following ranking:
1. GOPPRR [MetaEdit+]
2. GME
3. DSL Tools [Microsoft]
4. ARIS
5. Ecore [Eclipse]
6. Visio [Microsoft]

Tech Rating:
"MetaEdit+ is one of the premier tools for designing DSM-based applications"
"extremely helpful in eliminating many complexities associated with application maintenance"
