Derives from name family

This page is generated from the code and must not be edited by hand.

Not available in this version. A file is suggested as made from another when their names belong to one family, the first is raw data, an image made from data or a table, and at least two separate kinds of evidence agree.

derives_from_name_family version 1

• Kind of rule: Pairs suggested for a look (proposes). Proposes that two files are related in one of the eight ways, for a person to look at. A proposal is never a conclusion.

• What it concludes: derives, named processed_from

• Reasoning: defeasible. A conclusion is usually right, and is retracted when a rule it names concludes against it.

• What it reads: one file at a time

Is it available in this version?

Not available in this version. It proposes pairs but names no set of files to draw them from, so it proposes nothing yet.

What would defeat it

It names no rule whose conclusion would defeat it.

Parameters

Parameter	Shipped value	May be	What it does
source_roles	["raw_acquisition", "derived_image", "tabular_data"]	list of text	Which roles the earlier file of a pair may hold. A narrow list keeps the pairs proposed to a few, rather than every possible pair.
minimum_support	2	whole number, from 1 to 8	How many distinct support families must agree. The parameter a sweep would vary, and the curve it produces reports coverage against conflict rather than a single objective.
