[BioC] how to store multiple relationships between nodes in graphNEL?

I'd like to find the best way to record multiple relationships
in a graphNEL object. The data for my graph comes from DIP, the
Interacting Proteins, where many protein interactions have several
kinds of evidence.
In other settings, I represent this as multiple edges, another solution
is needed here, since graphNEL is designed for at most one edge
So I am improvising, packing any number of experimental methods into
list in a single edge's edgeData. Here is an example of one pair of
yeast proteins observed
by three different methods:
edgeData (g, 'YCR084C', 'YBR112C', attr='edgeType')
 "Immunoprecipitation::Affinity chromatography::Gel
Could I be doing this a better way? And how could I best store the
pubmed id associated with each method?
