Sorry, Rick, it was not my intention to break the rules of this mailing list. Where can they be found?
Regarding pg2: If one interprets process groups as the same as what I called domain in my example, then pg2 is the same as my process registry with additional support for distributed processes and lacking support for specific process attributes.
I guess at the end in my system a process needs to find another process by querying for: class ('I am searching for a parser...'), function API ('... which supports getLine/2') in its process group/domain. And as answer it will need the module where the target's API is implemented as well as the process' PID or name/node.
Pg2 is interesting. Bit cleaner than my version. ;)
Should have found that myself but I still haven't internalize the whole library functions.
