Hi, I decided to give a try to Aare or Workflow in Pharo 6, following instructions in https://github.com/Netstyle/Workflow . However, the installation script raised a Warning about missing WADynamicVariable class. Should I install Seaside? I've been using a couple of bioinformatics workflows the last years, specially Taverna (https://en.wikipedia.org/wiki/Apache_Taverna) and Galaxy (https://www.galaxyproject.org/) both of them huge code bases maintained since some years now and with very active communities from biological sciences. I found a cool video showing Galaxy features: https://www.youtube.com/watch?v=rVYzMWWRMN8 As impressive as you may think, they are not a Panacea for workflow execution. An installation process could get really complicated, for example interfacing with nginx and PostgreSQL, and customization of toolshed could end in endless editing XML specifications. I just skim through the white paper, but unfortunately didn't recognized any of the compared features or workflow systems. Is Aare intended to support only business workflows patterns? Considering the Galaxy video above, do you think scientific workflows could be supported in Aare or it is a completely different route? Cheers, Hernán
