Use "data item" terminology consistently throughout and improve textual definitions for several terms:

• IAO_0000027 data item

  • minor change to textual definition: An information content entity that is intended to be a truthful statement about something (modulo, e.g., measurement precision or other systematic errors) and is constructed/acquired by a method that reliably tends to produce (approximately) truthful statements.
  • remove editor note by JAR
  • change status: ready for release

• IAO_0000009 datum label

  • change label: data item label
  • add alternative term: datum label
  • change textual definition: An information content entity that is part of some data item and is used to partially define the denotation of that data item.
  • change status: ready for release

• IAO_0000003 measurement unit label

  • simplify textual definition: A data item label that denotes a unit of measure.
  • change status: ready for release

• IAO_0000100 data set

  • change status: ready for release

• IAO_0000109 measurement datum

  • change label: measurement data item
  • add alternative term: measurement datum
  • change status: ready for release

• IAO_0000032 scalar measurement datum

  • change label: scalar measurement data item
  • add alternative term: scalar measurement datum
  • change status: ready for release

• IAO_0000414 mass measurement datum

  • change label: mass measurement data item
  • add alternative term: mass measurement datum
  • change status: ready for release

• IAO_0000408 length measurement datum

  • change label: length measurement data item
  • add alternative term: length measurement datum
  • change status: ready for release

• IAO_0000416 time measurement datum

  • change label: time measurement data item
  • add alternative term: time measurement datum

• IAO_0000582 time stamped measurement datum

  • change label: time stamped measurement data item
  • add alternative term: time stamped measurement datum

Partially discussed on OBI/IAO call 2014-03-31.

• IAO_0000027 data item
  • do not remove JAR editor note
  • change status: pending final vetting
  • add editor note linking to http://odontomachus.wordpress.com/2014/03/30/aboutness-objects-propositions/
• IAO_0000009 datum label
  • seems problematic: Only a parent to one term in IAO. Also a parent to "categorial label" in OBI, but that term might be misplaced.

For terms which are singular we should keep datum as data item is too general. (IMO)

Reviewing choices. datum label: No change unless new example of usage. same for anything not mentioned below.

data set -> data item set (AR agrees)

time stamped measurement data item measurement datum -> measurement data item

But check if there are unpleasant interactions with the current definition of data item set

Ideally also change data item set to add axiom that it has min 2 data items (but this conflicts with transitive property)

Could be done with DL-safe rules, or we could document that we want people to use has_member and then add the cardinality restriction there.

To make one more specific, e.g. mass measurement item set, use: (has_part only ('mass measurement datum' or not ('measurement data item'))).

Add editor note to this effect.

Discussed on OBI/IAO call 2014-05-05. We will not make these changes to labels. I will make the following minor changes:

• IAO_0000027 data item
  • change status: pending final vetting
  • add editor note linking to http://odontomachus.wordpress.com/2014/03/30/aboutness-objects-propositions/
• IAO_0000100 data set
  • add editor note: Data sets include multiple data items, a data set with zero or one entry is a contradiction, but we have chosen not to add logical axioms in support.

If there are no objections, I would also like to upgrade the curation status of these two terms:

• IAO_0000100 data set
  • change status: pending final vetting
• IAO_0000109 measurement datum
  • change status: pending final vetting
