This switch in threads is satisfying. In my thesis proposal [1], I
defined federation, the process, along the lines of its dictionary
definition, to bring together, but to do so without filters (perhaps
other than those associated with legal issues). Let me contribute a
few thoughts.    (01)

A knowledge federation, as I see it, is a collection of points of
view, justifications for those points, arguments, and much more.    (02)

It is always useful that any point of view be anchored in concepts
defined in some ontology, but not all artifacts in the federation will
be so grounded.    (03)

My own work is to build topic maps, not in the traditional XML DTD my
book on topic maps talks about, but instead, in the way prescribed by
the topic maps reference model (TMRM) which simply expects you to
capture topics in proxy objects which are containers for what GOFAI
calls slots and fillers.  I read ontologies of various kinds into one
space, then map them to topics in the topic map to provide anchors
where needed.  I use the Bigdata triplestore, but not OWL, for my
topic maps. My most recent work explores the intersection of
conceptual graphs and topic maps.    (04)

All that to federate our world views.  The rubric for that is
"knowledge gardening" [2].    (05)
