- remove the notion of "Fingerprint" from the model. Instead, represent sets of labels, descriptions, and aliases separately, to accommodate future types of entities.
- Mention the notion of "unique features" in the model. Unique features for properties are (language + label) and (language + alias), unique features for items are (language + label + description) and (siteid + page). See also T74430
- Clarify the relationship between the logical data model (which is an abstract description of a data structure) and the conceptual schema (which is a semi-formal ontology of real world concepts).
