Here is something interesting I put together:

CAPITIS DIMINUTIO MAXIMA: The highest or most comprehensive loss of status. This occurred when a man's condition was changed from one of freedom to one of bondage, when he became a slave. It swept away with it all rights of citizenship and all family rights.

Capitis diminutio maxima is when something is spelled with all capital letters, and signifies surrender of not only familial rights, but also personal rights. This is when an entity becomes a corporation, property.. reduced to Roman slavery under Canon law. Which is why any official appearance of your name is always in all capital letters.

CAPITIS DIMINUTIO MEDIA: A lesser or medium loss of status. This occurred where a man lost his rights of citizenship, but without losing his liberty. It carried away also the family rights.

Capitis diminutio media, which is when you spell a word beginning with a capital letter, signifies the surrender of one's familial rights.

CAPITIS DIMINUTIO MINIMA: Tile lowest or least comprehensive degree of loss of status. This occurred where a man's family relations alone were changed. It happened upon the arrogation of a person who had been his own master, (sui juris,) or upon the emancipation of one who had been under the patria potestas. It left the rights of liberty and citizenship unaltered.

Whenever you spell something in all lower case lettering, under Canon law it signifies that you reserve all of your rights. This is called capitis diminutio minima.
