dm4-import-export: upgrade to 4.7

[Malte]

Let's remove the export import functionality via JSON for the upcoming release completely (from the GUI, since it is yet unfinished business) and just deliver the "Export Topicmap to SVG".

The SVG file export definitely needs to be adapted to the new file-repo service.

Source Code:
​https://github.com/mukil/dm4-import-export

[Malte]

To continue to work this plugin implementation needs to know the path (absolute path to a workspace file-repo), for a given request since it utilizes a "XMLStreamWriter" to assemble and write a SVG document into a file-repo.

See ​https://github.com/mukil/dm4-import-export/commit/3a44025cd5aa26de179e72123e63271221e5bd7f

[Malte]

Now, when per_workspace=true and utilizing the FilesServive?.getFile("/") (thanks to jri's hint #815), the SVG export works OK. Despite there is no "File Topic" created for the exported file in DM4, the SVG Document was written into the configured file repo.

SVG Export is (despite the missing file topic) working for both conditions (with per-workspace filerepos and with a global filrepo).

JSON Export works fine when the per-workspace setting turned OFF.

If per-workspace is on, the JSON Export document is written to the hard disk but the FilesPlugin? throws an Exception because of the impossibility of creating a workspace assignment when just doing:

String jsonFileName = "topicmap-" + topicmapId + ".txt";
return filesService.createFile(in, jsonFileName);

Here is the log:

See this posting for a discussion of this problem:
​​http://lists.deepamehta.de/pipermail/devel-lists.deepamehta.de/2015-November/000605.html
See #884 for the aimed solution.

[Malte]

Yes, thanks also to your mailing list reply this was solved with a commit 10 days ago.

The 0.3 Release was yesterday:
​http://download.deepamehta.de/nightly/dm47-import-export-0.3.jar

See "Version History" here (for more details on this release):
​https://github.com/mukil/dm4-import-export

[jri]

Let's remove the export import functionality via JSON for the upcoming release completely (from the GUI, since it is yet unfinished business)

To my knowledge this simple use case was functional already: JSON export/import a topicmap from one DM standard distro to another DM standard distro, that is when no custom types are used. I think this is still a useful function and it should be added again.

[Malte]

Of course, JSON import and export functionality comes back with a maintenance release of the plugin. You can download the new version from here:
​http://download.deepamehta.de/dm47-import-export-0.3.1.jar

Great!
Thank you!
