Subject Re: Ignite community is building Calcite-based prototype

Hi Denis,

Great initiative! It will be a great opportunity for the two communities to
learn from each other.
Personally, I am too far to attend physically but I find Julian's idea for
an online meeting very appealing.
If there will be such an option I will try to join.

Best,
Stamatis
