Forum OpenACS Q&A: Response to Using OpenACS 4 for development NOW
Although I have some work to do before ETP is ready for others to use, you could make preliminary versions of your page templates right now, which is where the bulk of the implementation work always lies. Make sure you've read the ACS templating documentation (http://developer.arsdigita.com/doc/acs-templating/ ) , and then design your master template and a template for each of your content types. A template that displays a single object should rely on a "onerow" data source (which is just a tcl array), and a template that lists objects of a particular type should rely on a "multirow" data source (which you can create with the template::multirow api). When ETP becomes available, it will be easy for you to make these templates present dynamic information from the content repository instead.
