@mdesalvo :hasMember
does not appear in https://www.w3.org/TR/owl-time/#geologictimescale
Where did you find it?
Note that the Geologic Timescale ontology extends OWL-Time.
It was documented here: https://link.springer.com/article/10.1007/s12145-014-0170-6 and maintained here https://github.com/CGI-IUGS/timescale-ont
There is a property thors:member
which is used to build temporal hierarchical ordinal reference systems.
Perhaps this is what you were looking for.
@nicholascar you may have more information from your work with IUGS.
Hi, the Turtle file of the Geologic Timescale example is here.
These are the triples describing the TRS, having the unknown property:
geol:TimeScale
rdf:type :TRS ;
rdfs:label "Geologic timescale" ;
:hasMember geol:Archean ;
:hasMember geol:Hadean ;
:hasMember geol:Phanerozoic ;
:hasMember geol:Proterozoic ;
.

Thanks.
The example is wrong. I will look into fixing it.
Hi, I'm developing a C# library for giving applications the ability to model ontologies containing temporal entities, so Time Ontology is the conceptual reference I'm following. I noticed, in the geologic time scale example, the usage of a property ":hasMember" which is supposed to be an object property from the legacy version of Time ontology (http://www.w3.org/2006/time#) but I cannot find it in the Turtle file.
So my doubt is: how can we specify the proper intervals describing a hierarchical TRS? This property may be missing from the actual draft.
Thanks, Marco
