Alice was beginning to get very tired of creating DSL graphical editors and of having too many things to do: start Eclipse, describe her domain with Ecore, generate the EMF code, launch another Eclipse runtime, specify her graphical mappings with Sirius Desktop, test with another Eclipse runtime, package everything to an update site, send it to Bob so that he can install it, help Bob who can’t find how to install the modeler, reiterate from the beginning to update the tool according to Bob feedbacks and needs… “Oh dear! Would you tell me, please, which way I ought to go from here?” she asked, “That depends a good deal on where you want to get to,” said the Cat. Alice prayed for a framework to easily create and deploy her studios to the web! Curiouser and curiouser! This talk is for you!
