I have developed a convention which I must define by example. I plan to call it the “gestalt” operator.
To take a {card|page} from REF1’s book - if you take a card from REF1’s book, it is metaphorically physically taking the card from REF1’s possession. Presumably you intend to give the card back to REF1. If you take a page from REF1’s book, it is metaphorically copying the page, with that page never leaving REF1’s possession.
To {fork|mirror} a repository - to create a replica of a data repository with the expectation of continued updates. A fork is one extreme: both sides will make independent changes after the cutover. A mirror is a different extreme: one side will make changes, and the other will faithfully replicate them. There are also various combinations. Before the trigger time, they are visibly identical.
To {partition|appraise} a collection - the executor divides the collection into several lots based on price, and offers (on a commission basis) to either divide the collection equally on price, to purchase some or all of the items at the stated price, or to duplicate the items at the stated price. When there is not a clear market price for the items, having multiple appraisers is recommended.
Gestalt means "an organized whole that is perceived as more than the sum of its parts". It is something like that; but sometimes more and sometimes less. The best way to describe it is the operation on a vector-based NLP system that takes {cat|dog} and returns "domestic pet".
There is a bit of a trick with the first example, {take a card|take a page} and "take a {card|page}" may mean something different.
For the second example, setting up a fork of Debian and setting up a mirror of Debian look very similar up to a certain point, but very different after that point. The term is intended to refer only to the attributes during the timeframe where they look similar.
