Research direction
Start by tracing PGFrames' edge dataframe handling and how its index is defined for source and target nodes. The work is complete when multiple edges between the same node pair can be represented using an edge identifier while retaining their distinct properties.
Written by the indexing model from the issue text.
Description
Currently, only one edge between a pair of nodes in allowed. For some use cases, it would be useful to support multiedges. For example:
Alice and Bob have two relationships, friends and colleagues, with different properties. It could be represented as:
@source_id, @target_id, @edge_id, @type, @since
"Alice", "Bob", 1, "friends", 1999
"Alice", "Bob", 2, "colleagues", 1998
Where the index of the dataframe with edges is given by @source_id, @target_id, @edge_id
