Class:ObjectClassification

[mtrekels]

Parent	ObjectGroup
Label	Object Classification
Definition	An informal classification of the type of objects within the ObjectGroup, using a hierarchical structure.
Usage
Required	No
Repeatable	Yes
Relationships	Range: ObjectGroup, ObjectClassification | Class-level properties: Reference, Identifier, MeasurementOrFact, ObjectClassification
Potential standards/vocabularies/ontologies to adopt
Notes	This class is used to categorise the ObjectGroup according to an informal, self-referential hierarchy. For example, this can be used to create a hierarchy encompassing biological, geological and anthropological collections, where a single formal taxonomy isn't appropriate.

This class does not seem very well scoped. Do we need it?
We already have preservationMethod in the CollectionDescription class

This does seem redundant with objectType. I don't see the use for a separate class here.

[wouteraddink]

if objectType are things like bark, blood, bones, eggs then I guess ObjectClassification is ment to have discipline specific classification, matching with DwC BasisOfRecord like PreservedSpecimens, FossilSpecimens etc?

[mswoodburn]

There's been a bit of confusion over this... I've updated the definition and notes to better represent the original intention, moved the taxonomic properties into a new Taxon class, and added some properties to enable the construction of hierarchies. An example of the intended us of this can be found in the SYNTHESYS+ Collection Digitisation Dashboard (https://rebrand.ly/synth-cdd), where it's used for organising the collections into 'discipline' and 'category' levels.

Could somebody (@mswoodburn ?) describe and delimit ObjectClassification in relation to CollectionDescriptionScheme?

1. Is ObjectClassification a "simple" form of CollectionDescriptionScheme?
   Is the intention to use it if there is only a single (or one main) classification hierarchy for the collection that in addition doesn't involve overlapping classes? Eg. based on museum departments ObjectGroups are defined and hierarchically structured by this ObjectClassification: {{{Invertebrates}Zoology}{{Ferns}{Mosses}Botany}{Fungi}{Lichens}Natural Science Collection}.
   As soon as a second classification is needed (eg. with a class "Cryptogams", or based on important collectors, the second classification is defined and described as CollectionDescriptionScheme. The first classification might be moved now to CollectionDescriptionScheme, too.

2. And/or do you use ObjectClassification to add a label (factor) that can be used for automatic approaches that are based on SchemeDimension? In that case the class ObjectClassification should be repeatable, or?

Sorry, I am completely lost. Intuitively, the three "Scheme" classes and this class seem to belong together somehow.
