This entity type represents an individual person. In my world view the person is the central object of the model. Most every other entity exists to serve the PERSON.
I'm copying Adrain's description here:
"When a person is first entered into a BetterGEDCOM (BG) file, using the data from a single source, the person entity will clearly contain just the information extracted from that single source. When a second source, apparently for the same person, is obtained and entered to the BG file, the user can then proceed in one of two ways:
Add the new information to the existing PERSON entity, so that the single PERSON entity always contains the current working hypothesis about an individual;
Create a second PERSON entity, using only the data from the second source. The first and second entities can be referred to as "evidence" entities. Then, assuming analysis justifies this, create a third PERSON entity containing the complete working hypothesis for this individual, manually selecting those accepted pieces of information from the first two "evidence" entities to put into the third PERSON, which we can refer to as a "hypothesis" person (or "conclusion" person providing we understand that these conclusions will probably be updated later)."
UUID - required - a universally unique identifier. (I'm not entirely sure any UUID will be truly unique across many systems. But that's the general consensus)
PersonKey - optional - a unique identifier which can be assigned by the researcher. By default it will start at 1 and increment for each new person. This gives a more user-friendly way of tracking a PERSON, than the UUID.
- optional - (M/F/U).
- optional - A limited choice field (Conclusion/Evidence).
- optional .
Surety - optional - a value on a scale indicating how certain the data is.
