   Technically, Pentaho libformula implements the `OpenFormula` standard. 
   The Apache POI variant I would call `POI Formula`.
   
   The main blockers for using the libformula library from Pentaho were the 
unmaintained status and age as well as the LGPL license on top of it.  To 
unblock at least the second part I had Gemini rewrite the library from scratch 
against the spec 
[here](https://github.com/ProjectDataHopper/hop-pentaho-formula/issues/1).  I's 
a green-field re-implementation so brought back to APL2 and can be further 
maintained under Apache Hop.
   
   @rmannibucau I would not abandon the progress you made just like that.  The 
arguments agains maintaining a separate stable set of formula is weak because 
it's essentially just bug fixing work.  
   
   For the migration work I can bring the APL2 OpenFormula variant into the Hop 
project as a drop-in replacement for the PDI/Kettle formula step.  This should 
allow migrations to continue while we see if we can fix the last couple of 
compatibility issues with the work Romain has been doing.  I'm happy to help 
out either way.  It's all for the best.
