Thanks Holger,
its difficult to keep track - but are sometimes path names
are relative to projects or are they always absolute? but i
see the clue was in the doc /exampleProject!
this raise a couple of other questions:
1) in a production EDG environment where we want to ingest
files programmatically, without the TBC project environment
being present, how are such pathnames interpreted?
TBC is not needed for production but the Eclipse workspace
will also be used in an EDG/TBL environment.
for example, I can see if we do a "one-shot" upload and
process that this works:
|_fileUpload| If|true|then files uploaded as part of a
multi-part HTTP request will be copied into the workspace as
temporary files. The name of the corresponding file will be
assigned to the argument variable. For example, define a
service with an argument arg:file of type string and create
a web form that uploads files as "file". The variable ?file
will then contain the path to the temp file in the
workspace. You can then use the function|smf:baseURI|to get
the URI of that file, e.g. to open it using|<ui:setContext
ui:queryGraph="..." />|. This is particularly useful for
Excel files.
what if we wanted to retain the files - they are not
"temporary" and we may want to use them later, or if we, for
example, wanted to go back and try re-processing a file, how
would we know how to find it - is there any way for example
to look at a directory and see the files.
If you don't use _fileUpload, XML files will become plain
string values that you can save to anywhere, e.g. using
sml:ExportToXMLfile. Then use the magic property tops:files
as in ?path tops:files ("/myproject.org/files/xml
<http://myproject.org/files/xml>" false) to iterate through a
folder of your choice.
2) is there a way to get the current project context, or
look up a project's local choice of path using some
metadata, or set a base context for file paths to be
interpreted? We already have a situation where the eclipse
import for different people have a different root because
some of us are looking at a single project, others have
opened a directory containing multiple projects, and the
scripts not longer work :-(
To be completely flexible, and to discover available files
and folders dynamically, use tops:files as above. Another
approach would be to parameterize the execution using some
kind of config file, for example a dedicated namespace that
holds local settings, and that is expected to be present in
each installation.

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
<http://example.org>" then use /example.org/file.ttl
<http://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?
