Table 1. Comparison of EHR paradigms: document-based versus FAIR-based.

Document-based paradigm	FAIR Principles-based paradigm
D1. Data entry is modeled around the clinical document, which is the output obtained from them.	F1. Data entry is modeled to respond to the needs of health professionals, allowing its use for health care and secondary purposes.
D2. Free-text or semi-structured data entry predominates.	F2. Structured and coded data entry predominates.
D3. Data do not follow common convergence models, so they are only understandable in the environment where they have been generated.	F3. Data are recorded and persisted based on health information standards, allowing them to be exchanged and transformed into other formats, without loss of meaning.
D4. The clinical domain concepts are implicit in the data tables, so that, the incorporation of new concepts implies an alteration of the data model.	F4. The clinical domain concepts are stored in tables independent of the data tables, making them flexible to incorporate new concepts without altering the data model.
