meeting has just ended. I must say it was a very interesting and<br>
productive discussion. We are really grateful for the developers from<br>
GRASS, SAGA and OTB for their contributions to our discussion.<br>
I recap briefly here what I believe are the most important outcomes:<br>
* we'll keep SAGA and GRASS Processing providers<br>
* we'll try to update SAGA provider to the next LTR when this will be<br>
available<br>
* we invite OTB team to add their work to QGIS core, granting them write<br>
access if they wish<br>
* for OTB provider, considering that OTB binaries are not part of the<br>
installer on Windows, we suggest this approach: OTB provider checks<br>
whether OTB is installed, if not it suggests the user to install it, if<br>
the user does not the provider hides itself<br>
* While we have granted an exception to the ‘processing providers should<br>
not be in core’ for the short term, our longer term plan is to put in<br>
place mechanisms to ‘side load’ the dependencies (GRASS, OTB, SAGA).<br>
When this capability is implemented, we will mandate that all providers<br>
will be provided as plugins and then fetch these plugins on demand if an<br>
algorithm references them<br>
* we will not accept new providers, unless some very strict and<br>
exceptional conditions apply (TBD; e.g. new backend of high quality and<br>
general usage)<br>
* for future versions we will consider moving providers to the XML<br>
approach where appropriate, as it appears more maintainable, even at the<br>
expense of flexibility in interface tuning; GRASS is the next candidate,<br>
noting that this might require some modifications in GRASS core<br>
* as a first step in we ask anybody to test thoroughly the new SAGA<br>
provider by Alex Bruy<br>

also a check from SAGA, GRASS, and OTB devs would be important, to check<br>
whether this approach is the preferred one from all sides.<br>
Please add if I missed something.<br>
Overall, I think we have now a brighter future for Processing, and as a<br>
consequence for QGIS, SAGA, GRASS and OTB altogether.<br>
* If you want to watch the complete discussion, please be patient; video<br>
is being uploaded.<br>
All the best, and thanks again.<br>
