Thanks Even

Still do you think I could have a brief intro if it's an in-tree driver. So 
from that point of view what would constitute a proxy and real driver?

John,


As stated in the intro, this RFC is mostly for *in-tree* drivers. If you 
develop an out-of-tree plugin that doesn't modify GDAL sources, then you can 
ignore it

Hello

Can anyone explain the concept of proxy driver and real driver in GDAL? I am 
looking at the link 
https://gdal.org/en/stable/development/rfc/rfc96_deferred_plugin_loading.html

Say I create an external plugin of some data format for e.g. say JP2 and then 
some Geospatial server loads my plugin file.


  1.
In this scenario I think the geospatial driver needs GDAL libs as well?
  2.
Now what is the proxy driver and what is real driver in this context? Is the 
real driver inside GDAL or inside my plugin?
  3.
What is the proxy driver in context of question (b)



Please clarify me so that I have clear picture in my mind.

BR
John
