True, you cannot change the Roller editor via Velocity scripts. There are two parts to Roller's UI: 1) Blog Editor and Admin UI - this is located at /roller-ui and is implemented using Struts2 actions and JSP pages with the Struts2 tags. 2) Weblog Pages and Feeds - this is implemented as a Request Mapper, a set of Servlets, Velocity templates, and infrastructure for running Velocity templates. To implement a mobile-friendly Blog Editor and Admin UI, you'll want to: a) decide on the right subset of Roller features to make available. You don't have time to rewrite the whole UI, so pick the most important parts. That probably means posting/editing blogs and, possibly uploading photos. b) decide how to implement the Blog Editor and Admin UI. How does a user get to the mobile interface, e.g. a special URL, perhaps? How should the interface be implemented, e.g. Struts2 on server-side plus Dojo on client side? To implement a mobile-friendly themes for the Blog/Pages part of the Roller, you'll want to decide when to show mobile version of a blog page, e.g. use HTTP User Agent to determine if request comes from mobile device. Might also want to allow user to opt for "full version" of a blog, and save their preference in a cookie. You also want to decide how a theme knows to provide mobile content. One way to do this would be to add a method to one of the theme objects to tell the theme that it is mobile. Each theme page could then include logic to show the right content. Another, possibly better way, would be to allow a theme to specify not only Weblog, Entry, Search Index and TagsIndex pages, but also Mobile-Weblog, Mobile-Entry, Mobile-Search-Index and etc. After writing all that, I think both Editor/Admin UI and Blog/Feeds theme this might be too much work for one GSOC project. You might want to focus on either Blog/Editor UI or Blog/Feed pages. I'd recommend Blog/Feed themes. I think its more important for Roller to be able to show blogs to readers on mobile devices than it is to enable Roller authors to write on mobile devices. To put tother a proposal, you'll have to study how the RequestMapper and associated Servlets work now to present a weblog via its theme and proposed how to enable a blog to have a theme that shows full sized pages for regular browsers and alternative pages for small devices.
