Observation Specialization #27

Closed KathiSchleidt closed 3 months ago

KathiSchleidt commented 4 years ago

Shall we continue to provide specialized observations, or should we shift to soft typing (would need observation types available via a common register)

KathiSchleidt commented 4 years ago

related to #18

dr-shorthair commented 4 years ago

I lean towards soft typing since the specialisations don't add any properties and only introduce a constraint. Of course in SOSA there are no specialised observations, but there is also less distinction between soft and hard typing in RDF.

KathiSchleidt commented 4 years ago

Is it possible to provide possible soft types for Observations within the OGC Registry? Would allow for soft typing of observation types What is the current status of governance pertaining to the OGC Registry?

Aren't they already there? Gobe and RobA are running it now.

The O&M 2.0 Observation Types are available here: http://www.opengis.net/def/observationType/OGC-OM/2.0/

ilkkarinne commented 4 years ago

As discussed in #47, the "type" attribute is now included in the proposed AbstractObservation UML class, see https://github.com/opengeospatial/om-swg/blob/master/iso_19156_issues/ea/2020-04-07_Observation.png

Implement with dcterms:type if it is just a tag or annotation, or rdf:type if it is an actual rdfs:Class

KathiSchleidt commented 4 years ago

Essential to provide good examples of soft typing, also how to transition from hard to soft typing

KathiSchleidt commented 4 years ago

Also need the references for the types, need by result type, nice-to-have by FoI type as example
