operators-ontology

This ontology provides a variety of operators designed for use with specifications that dictate that the value for some characteristic must be in some range. Two common use cases for these operators are:

1. Version dependencies. For example, one ontology might depend on the version number of an imported ontology being in a certain range.
2. Product specifications. For example:
   1. A product specification for a lotion requires that the concentration of a toxin must be less than so many parts per billion.
   2. A product specification for a smartphone requires that the battery life is greater than so many hours.

Operators provided include

• equal to
• greater than
• greater than or equal to
• less than
• less than or equal to

Also included is the ability to specify a target value with an absolute or percent variance around that target.
