Hi Luc
Looks like the $node.data_map.keywords.content.related_objects and $node.data_map.keywords.content.related_nodes have nothing to do with keyword relations, but are only concerned with explicit relations through the relation or relations attribute type.
This is definitely not the case for me, the nodes/objects in my example did not have any other relations at all so the relation was only created by the shared keyword. The part in your SQL statement that caused problems is usually related to permission and owner checking so you might want to try whether it makes any difference if you are logged in as admin or not. Also make sure (at least for testing) that the objects that should be related via keywords do not have different access permissions and are in the same section. Actually I just realised that I do not know the version of EZ you use. If it is an older version you might want to test your setup on the newest version - maybe the problem was fixed meanwhile. In case it helps find below the sql output I get when I do the following:
{def $node93 = fetch('content', 'node', hash('node_id', 93))}
{def $dataMap = $node93.data_map}
{debug-timing-point id="foobar"}
{$dataMap.keywords.content.related_nodes}
{/debug-timing-point}
debug-timing-point START: foobar

Don't forget that for the related_nodes to work, the objects must have the same class. Good luck Claudia
