Hello, I've released a major upgrade of PageProperties extension
and completely rewritten the extension page
most of the recent work is intended for the use in conjunction with Semantic MediaWiki
(it now offers a complete GUI based on OOUI to interactively create/edit properties, create/edit forms and even
to perform a semantic import from csv fields to local properties registered in the Wiki).
However at the same time the extension can be considered a proof of concept for the use of
Slots, since all the data-structure is completely based on SLOTS
(properties associated to a page are recorded within a slot with JSON content model)
and they can also be navigated through the interface.
The extension makes also significant use of the OOUI library, and I want
to thank the authors for their wonderful work.
If you want to check out the extension, I've set up this wiki
where you can freely test it.
I also plan to contribute whenever possible to the development
of MCR/slots for the coming versions of Mediawiki, since currently
the extension uses at least one hack, and the edit of slots
in addition to the first could in my opinion be strongly simplified possibly with a
a few changes in the code base.
best
