How to encode 2 possible dates for an event?

[oliber]

Hi!

In the very specific case of one of my ancestors, for whom I only have a fragment of his birth register, I have 2 possible dates for his birth date: https://gw.geneanet.org/oliber?p=philippe+vaast&n=berten
Geneweb has a ‘OR’ modifier but Gramps doesn’t…
What’s the best way to encode that into Gramps?

However odd this may be, I record two events in this case. Since this is “anomalous”, it draws my attention for further research.

If possible dates are relatively close to each other, I use an “imprecise date” between yyyy-mm-dd and yyyy-mm-dd.

Be aware there is no “best” way to encode this. Use whatever fits your mind and proves handy for you.

EDIT
Forgot to mention that all my records receive a tag to assess remaining work to do on them.

• brand new records are new with red colour
• in-progress ones are partial with colour turned green
• complete and reliable ones have no tag, thus they display black
• “dead-end” records are no follow-up with colour gray
• unprovable records (because of law on publicly available data, …) are restricted with colour brown
• records which incur missing data because of destruction (war, flood, fire, …) are tagged lapse with colour orange

Therefore, “anomalous” double event will also be tagged new or partial. Perhaps I should add a doubt tag to emphasise the context.

GEDCOMv7 has additional feature for disproven data. I do not see similar expansion for an “or”

Although well-intentioned, it seems to me that they are making a mistep and adding clutter to the data structure.

The QUAY tag already touched on assessing confidence in supporting data.

It seems that an expansion into a negative QUAY scale would be more appropriate. Where -3 would indicate a NO status.

And competing unique events, each at QUAY level 1 (questionable reliability), could indicate an ‘OR’ status at equal probability.

NO (Did not happen) g7:NO

An enumerated value from set g7:enumset-EVEN identifying an event type which did not occur to the superstructure’s subject. A specific payload NO XYZ should only appear where XYZ would be legal.

See NON_EVENT_STRUCTURE for more details.

g7:enumset-QUAY

Value	Meaning
0	Unreliable evidence or estimated data
1	Questionable reliability of evidence (interviews, census, oral genealogies, or potential for bias, such as an autobiography)
2	Secondary evidence, data officially recorded sometime after the event
3	Direct and primary evidence used, or by dominance of the evidence

Although the values look like integers, they do not have numeric meaning.

The structures for representing the strength of and confidence in various claims are known to be inadequate and are likely to change in a future version of this specification.
