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" 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?
