ConceptExplanation
Data SourceA source of data where Bill of Material (BOM) information may be pulled from or pushed to
Property MappingA mapping of meta data from one data source to another
Accessor

The key name of a meta data object that is retrieved from a source. In the object

{ "name" : "andries" }


the accessor (key) is 'name'

Rules

A rule lets you edit a cell value automagically.

It is typically used as a business rule that determines the final shape of the data.

For example,

"All quantities must be formatted as a 3 digit decimal", so we specify a rule to do it.

DerivativeA file created from another file. E.g. a PDF is a derivative of a drawing. A STEP file is a derivative of a CAD model
