[Qgis-user] save a join between attribute and table in gpkg?

[Mike Bundock]

hi
we had a similar issue in that we could not find a way of saving join
information.  The technique we ended up using was to extend the qml syntax
to support join field definitions, and use a small function to re-establish
joins correctly. This is really useful if the same sets of tables are used
in multiple projects.  Its simply a matter of loading the qml files using
the layer -> properties -> load style function.

We also use it as an easy method to define the join fields within other
applications such as Augview.   It means that UI behaviour within multiple
applications is consistent and only needs defining once.

hope that is helpful. If you want to use the same syntax, let me know & i
will send some documentation.
