For "part", perhaps substitute sequence_id, so the points can be sorted
into the original order?
Or this might have been what was meant by Michael anyway :-)

Hi,
Just a thought for a "convert geometry to points" v2.0
If you add three attributes to each point : point, line, and part
indices
you'll be able to create a plugin to convert the points back to the
original geometries
I can't describe a particular use case but I have already been asked for
that (may be useful if you have to process the data out of jump to do
special data transformation)
