Hi again, this is my last question and the more general one of the day :-) Iâm looking for way of representing and executing simple "business processes" in Pharo and a way of declaring domain ontologies/taxonomies. I didnât find any lib around this subjects except some projects in other smalltalk dialects. I just wander if somebody has done some work in these field. Iâm also interested in (KISS) design discussions around these topics, hence this email. I donât want to do a full fledged business process middleware. I would need : - a way to represent simple business processes (succession of activities with logic gates (and/or/xor) => I might be able to do that by myself). - a way to execute these processes (routines) in a semi-aotumatic manner => This looks more difficult to do to me. => my aim is to execute recurrent routines (my routines) with the help of a Pharo application For such a system, I also need a way to categorize information context. Again, I donât think I need a full fledged ontology implementation like Description Logic (or whatever). I think Iâll be happy with information tagging according to a predefined taxonomy. Instead of flat tags, Iâd like them to implement some sort of multiple inheritance. For instance, I may need a tag #soccer that "inherit" #sport. Any information regarding taxonomy tagging in Pharo ? (Or eventually ontology?). TIA, Cédrick
