hello, 

    I would like to announce, as per the subject, a major upgrade

of PageProperties which is now a "full-fledged metadata

management framework based on json-schema able to easily record,

organize and query collection of data on your wiki".

 

The most important changes of the current version are a

json-schema compliant SchemaBuilder (which does not support

yet the complete json-schema vocabulary, however is deeply integrated

with OOUI and Mediawiki)

and the dropped dependency from Semantic Mediawiki (that can be

optionally supported but does not constrain the features of the extension)

 

Furthermore, the recursive nature of json-schema allows to handle

hierarchical and nested data in a natural way: see for instance the Infobox

in this page https://wikisphere.org/wiki/Test_pageproperties_2.0 

that is rendered using the template result format, applied both at root

level and to subitems.

 

Here is the updated extension page https://www.mediawiki.org/wiki/Extension:PageProperties

however the first link is a better entry point to explore the features of

the extension since the documentation is organized in multiple pages.

 

Hope it can be useful to meet some of your data/metadata

management requirements (both at personal and professional

level) and that could possibly inspire the use of metadata

by regular users.
