Wrapping the expression in a fetch function as follows works:
fetch(names, select(nodes(enron_emails,
nodes(enron_emails,
walk="kayne.coul...@enron.com->from",
trackTraversal="true",
gather="to"), walk="node->from",
scatter="leaves,branches",
trackTraversal="true",
gather="to"), node as from), fl="name", on="from")
however, the response loses some of its structure and no edges are
returned, i.e. it becomes:
<?xml version="1.0" encoding="UTF-8"?>
<graphml xmlns="http://graphml.graphdrawing.org/xmlns";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns
http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd";>
<graph id="G" edgedefault="directed">
<node id="null">
<data key="from">kayne.coul...@enron.com</data>
<data key="name">Kayne Coulter</data>
</node>
<node id="null">
<data key="from">randal.maff...@enron.com</data>
<data key="name">Randal Maffett</data>
</node>
...
</graph>
which can be used as a subsequent request to the first in order to retrieve
additional fields but it would be more efficient if there's a way to
retrieve the required fields in one request.
