design - What is a "field"? "Field" vs "Field Value" -


There is a field in a passport: First name , and the value in that field is John .

I believe that the relationship is right to describe:

area first name :

  1. a name (First name).
  2. is a set of valid values ​​(for example, regex [a-za-z.] {1,30}
  3. defined by a description (name is the full name of the person

and passport is a set of pairs (field: field value), such as:

  • A field in the passport is "first name"
  • The field is for the field "first name"

    Right The path (perceptual / academic) is to say: "Passport Has the value of 'John' for the 'First Name' field.

    In practical terms it means (Pseudo C #): 

      Structure passport {map < Lt; field, object & gt; fieldValues;} Struct field {string name; string description; bool isvid value (object value);}

    question: Which means? Any ideas?

It is very subjective and completely sensitive, and a silly Looks like the thing.

True or not, if I am discussing "passport" with colleagues, then I will throw some of them, if I say every time I say "the first name is' John '', and Told me to say "the first name of the passport field is 'John'. You will just come in the form of annoying.
