Re: Can/Should property constraints be non-local resources?

An olsc:Property referenced by an oslc:ResourceShape with olslc:property must be in the same RDF graph as the resource shape. This has been a requirement since OSLC core 1.0.

I surveyed several of the shapes RDF data of our OSLC specs, and it seems that all property constraints are defined as local nodes. All are defined within their containing resource constraint. For example, see https://docs.oasis-open-projects.org/oslc-op/core/v3.0/os/core-shapes.ttl

Hi
I surveyed several of the shapes RDF data of our OSLC specs, and it seems that all property constraints are defined as local nodes. All are defined within their containing resource constraint. For example, see https://docs.oasis-open-projects.org/oslc-op/core/v3.0/os/core-shapes.ttl
but, when I read about the Core Common Properties (https://docs.oasis-open-projects.org/oslc-op/core/v3.0/os/core-shapes.html#CommonPropertiesShape), I would have expected these to be globally defined, so that other resource shapes can refer to them. But this does not seem to be the case. The Core shapes (https://docs.oasis-open-projects.org/oslc-op/core/v3.0/os/core-shapes.ttl) only contains resource shapes with their own locally defined properties.
Does this mean that the table in section “2.1 Properties on Any Resource” is only textual, and has no equivalent in the ttl files? Does this mean that it is not a good praxis to define property constraints globally?
