Is digitization a form of measurement? What about Photogrammetry?

[dshorthouse]

@PietrH Good question. The intent of this term was to align with the existing DwC term, http://rs.tdwg.org/dwc/terms/measurementDeterminedBy. Should we have a more granular definition here than that DwC term?

[PietrH]

@dshorthouse I'm a bit confused, so the value of measured: would be a string of person names? or person identifiers? What is the added information of repeating this over just using measurementDeterminedBy in the MeasurementOrFact table?

The ideal solution would be if the MeasurementOrFact table could refer to identifiers in a 'people' table where all the other information can be found. As using just string such as the http://rs.tdwg.org/dwc/terms/measurementDeterminedBy example Peter Desmet | Stijn Van Hoey can still lead to ambiguity about who exactly you are referring to.

@PietrH – what you're commenting on here is an option for an entry in the #22 term as part of the Actions controlled vocabulary. So in your example, a partial tabular representation in the extension might look like this, with occurrenceID here the foreign key to a single entry in the core:

occurrenceID	name	identifier	action	displayOrder
1001	Peter Desmet	https://orcid.org/0000-0002-8442-8025	measured	1
1001	Stijn Van Hoey	https://orcid.org/0000-0001-6413-3185	measured	2

Now, what you are also touching on is the notion that we already have an Extended Measurement of Fact as an extension to Darwin Core and it too has a term, measurementDeterminedBy as does the core. This is functionally equivalent to a identifiedBy term in the Darwin Core Identification History extension where it too has exactly the same term in the core. So, what is the lateral relationship between these terms in extensions to this present draft extension and how it more granularly represents actions and agents? In a word: none. The only partial solution to this is as @matdillen suggests and use the newly minted GBIF namespaced terms like recordedByID, identifiedByID in amended versions of those other extensions and ask that there be a full complement of options for all the actions we have represented in this controlled vocabulary such as measuredByID, preparedByID, etc. That's as ugly as it sounds.

The act of recording a measurement of or fact about an rdfs:Resource (http://www.w3.org/2000/01/rdf-schema#Resource).

This would be a direct reference to the existing TDWG term MeasurementOrFact http://rs.tdwg.org/dwc/terms/MeasurementOrFact
