RDFS and OWL define a few properties that are to be used to describe classes and properties e.g., RDFS:subClassOf for classes. These are available in EDG because RDFS/OWL defines this.
There are also properties like RDFS:label and comment that are traditionally used in ontologies. They are available in EDG for classes and properties because TopQuadrant added definitions (shapes) for them. A given ontology may decide to use other properties when describing classes. For example, RDFS:seeAlso or SKOS:altLabel or my:canonicalExample. This is typically done without declaring that a given property will be used to describe a class and what it’s values should be. Such practice presents an issue for editing tools. Without definitions they can’t know what fields to make available for a given resource and what their values may be e.g., should this be a number, a string, HTML, image, link to another resource, etc. When one loads an external ontology into EDG, they will be able to see values of such “undefined” properties, if they check the box for this option in the Form’s settings menu. However, they will not be able to edit the values - as no shapes exist for them. To be able to create and edit values of these properties, there needs to be a shape defining them. Rob is asking if anyone already created some additional useful shapes for describing classes that they are willing to share. > On Jul 21, 2021, at 2:35 AM, 'Bohms, H.M.
