Hi!
What about people who were born in the 18th-century? We know they are
dead, but their death is not recorded and we only know when they were
last active. How do you set that end date?
That's what somevalue/unknown is for.

For the unknown date case, I also used some imprecise dates in the past, if
you set date withe a precision of the century around the last time it wa
known active for example, you get something semantically correct and that
is probably esaier to handle in queries (athough the way to handle

Hoi,
There are two ways of doing that.. You can assume given average age and
date of birth in what century someone died. This is something you can
specify or you can state that the date of death as unknown. Now that IS a
valid way of doing this. However it does not mean that 17th centrury people
Hoi,
It would make sense to have a bot run and add dates of novalue for dob dod
where we know that people must be dead.

That would actually be opposite of what we want, since novalue would
mean they were not born and are not dead. I think you meant unknown
for date of death, in which case it
Could you not add the last active date as a qualifier to the somevalue
death date?
In general uncertainty in dates are not so easily entered. Born 1969 or
1970 cannot be entered as 1969 with uncertainty decade since that becomes
1960s (at least that is what is shown to readers) so the only legit

Hoi,
As you know I am not a fan at all about these special values. I can follow
logic but do not need to agree.
When novalue is not to be seen as a value. What is the point.. The point
is to state there is no value right ? .. and that makes it of value. Right
ahum, I admit it is confusing but is
Quick reply to Denny and Gerard:
@Denny: I think it makes sense to treat qualifiers under a closed-world
semantics. That is: what is not there can safely be assumed to be false.
In this I agree with Gerard. OTOH, I don't think it hurts very much to
add them anyway.
@Gerard: Please note that
Actually I think that having no value for the end date qualifier probably
means that it has not ended yet. There is no other way to express whether
this information is currently merely incomplete (i.e. it has ended, but no
one bothered to fill it in) or not (i.e. it has not ended yet). This is
Hoi,
When someone bothers to add a qualifier, it is most likely that it will be
done completely and well. It is NOT something that is automated. So a date
missing means exactly that. There is no known end date.
This notion that no value has value is fine except that it prevents tools
that rely on
