a model with a set of generic standards and modeling constructs
a series of devices for achieving a better understanding of vague language patterns, including specific questions for added clarification.
A model developed by John Grinder and Richard Bandler that identifies categories of language patterns that can be problematic or ambiguous.
in the field of NLP the Meta Model is a language tool that provides questions to help uncover, specify and clarify information, which in everyday verbal or written language may have been lost through habitual patterns of distortion, deletion and generalisation. Developed by Richard Bandler and John Grinder.
The CASE tools provide various alternative modeling techniques at both the business and implementation levels, such as entity relationship modeling. When designing a CASE tool these models must themselves be modeled. This is known as meta modeling. A example would be to add new properties into the CASE tool. See also extensibility.
