Base ontology: Suggest the range of PhysicalSample.hasStratigraphicUnit is a gazetteer of named instances #57

Closed krisnadhi closed 9 years ago

krisnadhi commented 9 years ago

Moved from #52

@robertarko suggests the range of PhysicalSample.hasStratigraphicUnit is a gazetteer of named instances (eg. from the USGS National Geologic Map Database):

Bonneville Formation Portland Formation Gray Gulch Formation etc.

Doug - comments ?

krisnadhi commented 9 years ago

Related to #55

Comment from me in #52:

Do we want to collect this gazetteer instance into a class in the ontology? If yes, we change the property into ObjectProperty. Otherwise, we simply keep the property as a DataProperty with xsd:anyURI as range.

krisnadhi commented 9 years ago

@robertarko @fils @sparkji Should we create a class called StratigraphicUnit to capture stratigraphic gazetteer names? Or should we simply say that hasStratigraphicUnit can point to any URIs?

sparkji commented 9 years ago

Yes, we should create stratigraphicUnit class to capture stratigraphic gazetteer names.

Are the stratigraphic gazetteer names available as URIs anywhere? Or are they simply string values?

sparkji commented 9 years ago

They should be available as both URIs and string value. On Sep 11, 2015 8:59 AM, "krisnadhi" notifications@github.com wrote:

But having a class StratigraphicUnit implies that all the names have to be available as URIs and string values should not be used (except only as a label), i.e., you cannot have a triple like :sample1 :hasStratigraphicUnit "Portland Formation"

sparkji commented 9 years ago

Ok. Let's create class StratigraphicUnit, and just use URIs for property hasStratigraphicUnit.

Okay. We got an agreement :+1: In any case, we could still add string information through the labels of the instances.

StratigraphicUnit is now added to the base ontology.
