Principle: Textual Definitions
The original wording of this principle (given below) and content of this page is scheduled to be reviewed. Improved wording will be posted as it becomes available.
textual definitions (SOP) for a substantial and representative fraction, plus equivalent formal definitions (for at least a substantial number of terms). For terms lacking textual definitions, there should be evidence of implementation of a strategy to provide definitions for all remaining undefined terms.
Text definitions should be unique (i.e. no two terms should share a definition)
- original principle, modified
- What percentage of terms defined is acceptable?
- Need clarification on
- text definitions
- text definitions written in formal style / genus differentia
- computable definitions (i.e. equivalence axioms / cross-products)
The ontologies include textual definitions for all terms. Many biological and medical terms may be ambiguous, so terms should be defined so that their precise meaning within the context of a particular ontology is clear to a human reader.
