Hello,
'Custom properties' (properties that do not have any sh:group assigned) section does no appear for entities that are defined in a Reference Dataset. They do appear if the entity is defined in the ontology. What is the reason for this behavior?
I attach test ttl files:
- test_onto.ttl --> ontology including class and instance ('Custom properties' section is present)
- test_onto_2.ttl and test_rds.ttl --> ontology schema including class + reference dataset including instance ('Custom properties' section is not present)
Thank you!
Eva Ibarra
test_onto.ttl
test_onto_2.ttl
test_rds.ttl

Hi Eva,

in EDG, Ontologies use the "old" forms while Reference Datasets use the "new" GraphQL-based forms where possible. The old forms do have a different algorithm, including the "Other Properties" section that serves as a wildcard for all properties that have values. In the new forms we made the decision to only show properties backed by SHACL property shapes. Among the performance gains this has the advantage that ontology designers can define specific perspectives or views on data, even if that data has additional triples. For example this also includes ways of limiting the properties that certain user roles are able to see.

FWIW, if anyone wants to drill deeper into this topic, this recently published page elaborates on forms generation:

To clarify, there is no need to assign sh:group to a property shape, but you do need to define a property shape for each of your properties. 

If there is no property shape for a property, the the property and its values will not appear on the “new” forms.

If there is a property shape and the shape does not have sh:group, then the property will appear on forms under Other Properties section.
