Can be augmented with colloquial definitions' is terrible.\n\nCan you fix to something like:\n\nA statement of necessary and sufficient conditions explaining the meaning of an expression referring to a class or property.\n\nAlan Ruttenberg\n\nYour proposed definition is a reasonable candidate, except that it is very common that necessary and sufficient conditions are not given. Mostly they are necessary, occasionally they are necessary and sufficient or just sufficient. Often they use terms that are not themselves defined and so they effectively can't be evaluated by those criteria. \n\nOn the specifics of the proposed definition:\n\nWe don't have definitions of 'meaning' or 'expression' or 'property'. For 'reference' in the intended sense I think we use the term 'denotation'. For 'expression', I think we you mean symbol, or identifier. For 'meaning' it differs for class and property. For class we want documentation that let's the intended reader determine whether an entity is instance of the class, or not. For property we want documentation that let's the intended reader determine, given a pair of potential relata, whether the assertion that the relation holds is true. The 'intended reader' part suggests that we also specify who, we expect, would be able to understand the definition, and also generalizes over human and computer reader to include textual and logical definition. \n\nPersonally, I am more comfortable weakening definition to documentation, with instructions as to what is desirable. \n\nWe also have the outstanding issue of how to aim different definitions to different audiences. A clinical audience reading chebi wants a different sort of definition documentation/definition from a chemistry trained audience, and similarly there is a need for a definition that is adequate for an ontologist to work with.

Connected to that, care should be taken with quantification and units of dose. Dose may be described as charge per unit area or charge per unit pixel. In specific EM application, typically beam lithography and focused-ion beam milling, instrument software may offer the possibility of calculating dose as charge per unit length or particle quantity.
