Generic solution for dealing with complexity degrees of conformity credentials

Created by: nissimsan

Conformity credentials come in different levels of complexity, and I would like to see this group suggest a generic data model to support this.

Example: A Mill Test Report can include a number of tests. But, say, a pressure test makes makes sense for a tube or a valve - but not a coil. The exact tests carried on a MTR depends on (at least):

• Type of product,
• Customer,
• Region/country/jurisdiction.

Two general thoughts come to my mind:

• Narrowly defined schemas, dedicated to for example specific products. I would assume there are applicable standards which can guide this subdivision.
• Inheritance, since a lot - but not all - elements on such different MTR types would overlap. Technically, though, this is complexity danger zone which I'd prefer to avoid.
