Hi Rob,
ui:dumpGraph requires a graph URI, so the solutions with one of the
temporary unnamed graphs would not work (as you have found out).
However, using ui:tempGraph does work as confirmed in the attached test
case.
The error handling with ui:tempGraph is not ideal (and I have just added
a better message for the next release), but what the null pointer means
is that it cannot resolve the path in your workspace.
In your case, /tmp/agentmodels_as_sxml.ttl, is there a project called
"tmp" in your TopBraid/Eclipse workspace? It needs to, e.g. if you had a
project "example.org" then use /example.org/file.ttl".
If there is a different null pointer in your case, could you send me the
stack trace?
Thanks,
Holger

OK - so I want to try using SPINMap to transform what default import
looks like into the target ontology...
so I'm trying to save the imported graph programmatically, because I'm
still not sure if manual import gives the exact same graph as import
using the sml:ImportXML - and AFAICT SPINMap needs a project file to
load for it its UI based mapping processes
- so, load and save example, set up SPINMap, invoke transformation
using SWP for multiple files in the same XML schema...
tried various things to dump the graph : (NB invoking
with &_contextdebug=true)
If none of these work, noting the graph loads (JSON print out example
provided by Holger works), then what will work and what is wrong with
these options?
