Add a schema configuration option that allows the definition of an inverse relationship for resource-based properties.

E.g., if a contributor property is defined and has a resource as target, the resources pointed to by this property should display a virtual property (i.e., in presentation only)contributed_to that points back to the previous resource.

This would allow to display bidirectional links in the presentation. It has no semantic value, and it shall not infer the reverse relationship in the database.

A few metadata points are required to display the relationship properly. E.g. for contributor.

{
    uri = "pas:contributor",
    label = "contributor",
    type = "resource",
    inverse = {
        id =  "contributed_to",
        uri = "pas:contributedTo",
        label = "Contributed to".
        description = "Artifact that this agent contributed to.",
    }
}

Optionally, as part of this ticket, a PROP_REFLECT flag, mutually exclusive with the inverse definition, can be defined. This would define a reflexive property, i.e. a property with an inverse that is exactly the same property (e.g., sibling).

Add a schema configuration option that allows the definition of an inverse relationship for resource-based properties. E.g., if a `contributor` property is defined and has a `resource` as target, the resources pointed to by this property should display a virtual property (i.e., in presentation only)`contributed_to` that points back to the previous resource. This would allow to display bidirectional links in the presentation. It has no semantic value, and it shall not infer the reverse relationship in the database.

E.g. for `contributor`. ``` { uri = "pas:contributor", label = "contributor", type = "resource", inverse = { id = "contributed_to", uri = "pas:contributedTo", label = "Contributed to". description = "Artifact that this agent contributed to.", } } ``` Optionally, as part of this ticket, a `PROP_REFLECT` flag, mutually exclusive with the `inverse` definition, can be defined.
