[Workaround] WOPI / OnlyOffice create new form file

[wkloucek]

Is your feature request related to a problem? Please describe.

I want to create new files for the OnlyOffice form editor. Forms to be created have the .docxf file extension (https://www.onlyoffice.com/blog/de/2022/03/onlyoffice-formulare-oform-docxf). It seems like there is no mimetype for it.

When looking at the /hosting/discovery endpoint of OO 7.4 it looks like the editor is the same for docx and docxf:

Therefore you can just create a .docxf file and edit it in the form editor view.

But I cannot configure oCIS to allow creating docxf forms without cannibalizing a different file format.

Describe the solution you'd like

A possible solution / workaround is to make up a mimetype for docxf files in REVA's pkg/mime/mime.go:

"docxf":                    "application/vnd.openxmlformats-officedocument.wordprocessingml.form",

Then I can configure following actions in the mimetypes section (in this example via the oCIS Helm chart (https://github.com/owncloud/ocis-charts/blob/49eea9b36cffa590b3e40b9e9aa0db1717101bbc/charts/ocis/values.yaml#L232-L243):

- mime_type: application/vnd.openxmlformats-officedocument.wordprocessingml.document
  extension: docx
  name: Text document
  description: Text document
  icon: image-edit
  default_app: "OnlyOffice"
  allow_creation: true
- mime_type: application/vnd.openxmlformats-officedocument.wordprocessingml.form
  extension: docxf
  name: Form document
  description: Form document
  icon: image-edit
  default_app: "OnlyOffice"
  allow_creation: true
...
...

It'll leave me with this "New file" menu in Web:

Describe alternatives you've considered

Probably we're doing something really complicated with the mime type to file extension conversion. We could probably unclutter that.

Not sure if you prefer another solution and/or more investigation. But if it helps to just add this mimetype you can have it quick and easy: https://github.com/cs3org/reva/pull/4116

[wkloucek]

I think adding non well known mimetypes is only a workaround. I think we should look at why we're doing a lot of complicated mime type to file extension conversions and vice versa.

Then let's plan this ticket properly for one of the next sprints. It is more a story than a bug anyways
