Hi all,
I think "QualityMeasure" is the most natural choice for people coming from
the quality domain, who in my opinion are   our primary target.
"QualityObservation" might result a little confusing for people who are not
aware of RDFCube terminology.
 I am almost sure to remember that  we decided to rename   daq:Observation
in DQV:QualityMeasure for the above  reasons.

I find interesting that ISO seems to use  the term "measurement" for the
action, and "measure" for the result of the action,

4.5 data quality measure
variable to which a value is assigned as the result of measurement of a
data quality characteristic

That might be a sort of answer to the  "measurement vs measure" doubt,  I
suspect the two words are almost interchangeable,  as the merriam webster
seems to suggest  in [1] and [2],   but  here I would leave the last word
to   the  native speakers ....
