Using Service > Create Relation do I need to explicitly create both incoming and outgoing relation?

[karl_harris_]

I am creating a relation between two documents with Services>Create Relation. How do I specify the predicate so both incoming and outgoing relations are created correctly.

I have used the String IsBaseOn in the predicate and when the relation is created IsBasedOn is the predicate for both directions of the created relation.

I sense there needs to be some type of indirection used to identify the predicate based on the message.en/fr/current language translation system but I can't see to find a reference to how to use label.predicate.... vocabularies.

Found that: http://purl.org/dc/terms/References and it's relatives works in the Service>Create Relation Predicate and creates incoming and outgoing relations.

One relation does create both incoming and outgoing relations. When displaying them in the UI, a cheap trick is used to display a different label by fetching labels from two distinct vocabularies.
