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? 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. 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 :-( rob On 15 May 2018 at 13:19, Holger Knublauch <[email protected]> wrote: > 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).
