Thanks,

  Nevertheless, I have just three kinds of asset collections in my version :

     - Taxonomies, Ontologies and Crosswalks.

For the second option I haven't this option also in my topBraid.

But why we can not edit instances by default please ?

There are various reasons for our recommendation that

- Ontologies should only contain classes, properties and shapes

- Instances should go into all other graphs

One technical reason is that changes to ontologies may cause internal overhead, e.g. rebuilding of GraphQL schema and other optimized data structures. In a typical project, changes to ontologies are much less frequent than changes to instances, so it's usually a good assumption that the ontology will be stable so that these other data structures can be kept stable too.

But also from a design perspective it is quite natural to keep ontologies/schemas and instances separate, because schemas are typically reused across multiple instance graphs. Exceptions are instances that represent enumerated instances, e.g. the colors of traffic lights, or the 12 months of a calendar.

Mixing schema and instances may be convenient for quick prototyping but keeping them separate is in our experience a good long term investment.

Best,

    We recommend putting instances into a graph different from an
    ontology e.g., into a taxonomy, reference dataset, data graph and
    many other asset collection types available in EDG.

    If you create instances in an ontology, by default, only label and
    comment will be editable. This can be changed on the Manage tab by
    checking the box shown below:

    Sorry I don't think I understand your exact scenario. Could you
    elaborate a bit? Are you using Ontologies or some instance asset
    collection such as Data Graphs/Taxonomies? That impacts which
    properties are editable. And on your first question, what do you
    mean they are not displayed?

    Some concrete example snippets would help.

    Thanks,

    Hi folks,

       I have two questions :

     1. I defined Node shapes with some properties shapes. When I
        try to use this NodeShape in an external ontologies
        (instances) I have my constraints applied correctly on my
        owl:Class but not displayed.
     2. I create instances, now, the properties are displayed but
        "read-only" and I can't edit the values of these properties.

    Thanks for your help and explanation.

    Best,
