Dear Frank,


Thanks for a well thought through set of definitions we can discuss and debate.  It’s a great beginning, but I have a quibble about one item, specifically:


A Grammar is a means of applying rules to create meaning.


Grammars don’t create meaning, they create syntax. 

Your related statement:


Syntax is a set of rules for structuring elements, such as words and symbols within a grammar.


is correct, and more accurate, in that it doesn’t mention the word “meaning”.  The only source of meaning is a human (or other subjective being) which bases meaning on that human’s stored experiences, emotions, values and goals.  Said experiences, emotions values and goals are unique to that human.

A Data Dictionary defines "data" by giving you details about that data element (e.g. Attribute/Field Name, Description, Data Type, Constraints, etc.)


So a data dictionary does NOT contain artifacts such as systems, programs, data structures, subroutines, etc. and all the other systems thingies that manipulate data elements?



Just wish I could do some sort of Venn diagram here as most of these terms are heavily overlapping.




Is this description of a data dictionary saying that a metadata repository is different from a data dictionary?  


If they're different, what are the differences?
