Ditto, except in this case, for more flexability, i prefer the XML tags still,
and do not like OOP. That way, there are no mandatory fields; there are no
fixed fields; there are unlimited descendants and inheritances, and they
can be ranked; data can be added at any time and place, and who added it
can be added; etc. The real world is not fixed, there are exceptions all over
the place, and what we "know" today may be wrong tomorrow,, so i'd hate
to be the one hard-coding an object form.
As an example, after i have forgotten my biology....
Bird = "<reproduction_method>lays eggs</reproduction_method>"
Mammal = "<characteristics>warm blooded</characteristics>
Cat = "<species>mammal</species><size>10lbs max</size>"
My_Cat = "<inherited_from>Cat</inherited_from>
<name>Alice</name> <covering>fur</covering>
<eye_color>green</eye_color>"
Janes_Cat = "<inherited_from>Cat</inherited_from>
<name>Fred<addedby>Susan</addedby></name>"
Platypus = "<inherited_from> mammal </inherited_from>
<inherited_from>bird</inherited_from> <reproduction_method>
<inherited_from>bird</inherited_from> </reproduction_method>"
what is Jane's cat size? = max 10lbs
What is my cat covering? fur
What is Jane's cat covering? unknown
Who told you Jane's cat's name: Susan
Is a Platypus a mammal? yes
Does a platypus lay eggs? yes
Of course, i have not verified any of the above data, but you get the idea.
The data is changeable at any time, and can be human-readable.
