CSDMS Standard Names — Assumption Names
- This document provides standardized assumption names for use in Model Metadata Files (MMF). They are organized into groups and are not meant to be exhaustive but more illustrative. The ones collected here already illustrate various language patterns that are commonly used to describe assumptions.
- Note that assumption is meant to be taken as a broad term that can include things like conditions, simplifications, limitations, provisos and other forms of clarification.
- CSDMS encourages model developers to include as many <assumption> tags in there Model Metadata File as they feel apply to their model or to a particular input or output variable name. XML tag nesting determines the scope of an <assumption> tag's scope. For someone familiar with a particular modeling domain, the terms that have been collected here should be easily recognized and understood.
