The LibreOffice extensions site is running on Plone with some addons. I’m currently working on a new flat structure of the site with new content types and views. I worked first on the structure that has only three content types instead of five now. The user (contributor) had only to create a project and could add releases with files to that project then.
I finished my work (draft status) on the content types for the contributors (project and release) first and drafted a view with features for the extension center in the last days. You could get the current status of the add-on from the github repository of the Document Foundation:
I’m looking for a resource where I could set up a test environment of the new site. A virtual machine will be created for this purpose by our admin team in the next days.
