Re: "thou shalt not conflate meta-data with data"

>> If a db models "john is a person, john is male AND male is a gender"
is male data or meta data? Can the same thing (ie male) be both data and meta data? And john would not be data according to you since john is a person. Is this what you meant? <<

[Quoted] John is a single entity in the set of persons. Persons have an attribute of gender, which takes on the value male. The representation of the value,say ISO codes (0,1,2,9), is drawn from a domain, which have a data type and constraints. All of these "levels" are completely different.
