obographs should distinguish between annotationProperty, objectProperty & dataProperty

[dosumis]

Current specification for node types has only:

                "type" : {
                  "type" : "string",
                  "enum" : [ "CLASS", "INDIVIDUAL", "PROPERTY" ]
                },

I guess that changing this enum now to distinguish OP, AP & DP is not possible as it would be a pretty major breaking change. Would it be possible instead to add a property_type key with enum:

["annotationProperty", "objectProperty", "dataProperty"]

?

(I'm sure I requested this several years ago, but not sure where - can't find ticket)

Use case: loading neo4j property graphs to allow subsequent conversion to OWL.

Notes from call between @julesjacobsen and myself. We agree with the proposal. We will add property_type on Node. This will only be filled if node.type == "PROPERTY".

To be consistent with existing conventions the permissible values should be ANNOTATION, OBJECT, DATA
