Min/Max Restriction for Observation Collection

[aurioldegbelo]

Hi all,

I am in the process of using sosa:ObservationCollection for a project, and realize that there is a restriction "sosa:resultTime max 1" for the ObservationCollection concept. I was wondering what the rationale for this is. In fact, shouldn't it be "sosa:resultTime min 1"?

Thanks for the feedback @aurioldegbelo

SSN-ext was a non-normative extension, published to trigger feedback for a potential addition in a future edition of SSN.

ObservationCollection has been added to the core SSN Ontology (i.e. in the sosa: namespace) in a new edition of SSN which is not quite complete, but available here: https://w3c.github.io/sdw-sosa-ssn/ssn/

There are no cardinality restrictions on collection properties.
The consistency rules for collections and their members are refined.

I suggest you use the ontology available at https://github.com/w3c/sdw-sosa-ssn/tree/gh-pages/ssn/rdf/ontology
