Discussed this with @Snaterlicious today. He said he'll work on his proposal a 
bit more. I think we can use that to replace the old primer. The formal model 
should probably be kept around. Some key points from the discussion:

- 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

- Clarify the relationship between the logical data model 
<https://en.wikipedia.org/wiki/Logical_data_model> (which is an abstract 
description of a data structure) and the conceptual schema 
<https://en.wikipedia.org/wiki/Conceptual_schema> (which is a semi-formal 
ontology of real world concepts).
