Principle: Textual Definitions
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.
