# 1st OpenPIV governance meeting

Date: Nov, 16
Topics: how do we manage OpenPIV better and how do we coordinate future developments


## Participants
Peter, Theo, Roi, Hadar, Alex


## Discussion

Peter: Java is maybe too complex we can learn from it. Python is maybe more welcoming to the new users. 

## GUI in Tk
with Erich Zimmer, Christophe (PhD from Peter's group)


Theo: Master student, VKI internship (we shall invite also VKI professors to contribute, )

Roi: we reminded C++ version of Zachary Taylor and long - term PIV development

Hadar: PhD student with Roi, Msc. with Roi/Alex, also on PIV, code from 2012, toolbox in Matlab post-analysis time resolved wakes, transient analysis of bird's wake.


## Matlab or Python or both? 
our community is not from programmers. language should be wide used
Matlab is commerically licensed
Resources are limited - focus on one language
is it a zoo of programs more than a single program? 

Hadar: Matlab is more maintenance than development. Bugs/features - minor requirements. 20% Matlab to 80% in Python

If we cannot provide maintenance, don't we loose community? 

Hadar - GUI, no need for Python knowledge. 

PIVLab - has a good algorithm and good GUI. 

--- 
Summary: Since PIVLab is better, we won't get any Matlab users anymore. 

MATPIV was good and left unattended, no support, with some sporadic developments

Large companies have Matlab, but they might also have Python 


## GUI
Put effort into GUI
command line vs GUI - how to make extensible, not close like PIVLab 
interact with input/outpus files

We have one code and GUI will be using calls to the same work. 

If there is a contribution - how to separate it in GUI from the command line 

several projects for everything 

plotting 

## Create website

Clear message - Matlab is not maintained, C++ is dropped (Zach is busy). 

## Post-processing
We need to get the also nice post-processing

post-processing is very individual - how to extract data and compare, average in special way, individual and done ones, 
separate projects
