import losd as l
pl = l.plainQueryValues
q = l.query

# get all snapshots:
query = '''
SELECT ?s WHERE {
  ?s a po:Snapshot
}
'''

res = pl(q(query))

##########
# from here on, check to assure that the uris correspond to
# the snapshot (types) intended

'''
res6 = pl(q(query))


# get all friendshipts in the Participa.BR snapshot:

query = '''
SELECT ?a1 ?a2 WHERE {
?f a po:Friendship . ?f po:snapshot <%s> .
?f po:member ?a1, ?a2 .

    res5,
    res6,
    res8,
    res9
]
friendship = [
    res2,
    res7,
]

fr = []
for relations in friendship:
    fr.append(l.mkRelationNetwork(relations))

inte = []
for interactions in interaction:
    inte.append(l.mkInteractionNetwork(interactions))

# finished. Play with the networks in fr and inte
# maybe use networkx and pylab to plat them
