Access information about page connections.

Edges represent the connections between resources. They are implemented as tuples {EdgeId, SubjectId, PredicateId, ObjectId, OrderNr}. The edge id is a unique id representing the edge, it can be used with edit actions. The OrderNr defines the order of the edges with respect to the subject.

Most edge information is accessed using the m_rsc model, but some information can only accessed with the m_edge model.

This model implements two template accessible options. They are mainly used to obtain the edge’s id for edit pages.

The following m_edge model properties are available in templates:

Property Description Example value
o Returns a function that accepts a page id and a predicate. The end result is a list of tuples {PageId, EdgeId} which are objects of the page. Example usage: m.edge.o[id].author [{204,13},{510,14},{508,15}]
s Identical to the “o” property, except that this function returns the subject edges.  

Look up an edge id by a subject/predicate/object tiple. Example usage:


Returns undefined when the edge does not exist; otherwise returns an integer.
