This details the design information for the RSF blog exercise (rsfBlog). For this exercise we will create a simple working blog tool designed to allow students to create and share blog entries in a sakai site.


  • Blog Wow will have 5 screens for this exercise
  1. Home view - includes a list of the current blogs in the site (the blog for this user will appear at the top)
    • blogs are created using a "start blogging" link at the top, anyone with the start blog permission may create a blog
    • this list should include the date of the most recent blog entry
  2. Blogs view - includes a list of all entries in a blog
    • includes add link and edit links for the owner of the blog (or admins)
    • includes link to remove a blog entry (with all associated comments)
    • also includes links to add comments (the link will indicate the number of current comments)
    • the owner information and a profile will appear on the right side of the screen
    • also lists all the current comments on this entry in order above the new comment textarea and submit button
    • comments cannot be removed
  3. Add/Edit Entry screen - allows the blog owner to create or update blog entries
    • this should update the modify date for a blog entry also
  4. Settings view - this allows the blog owner to edit their profile
  5. Permissions view - uses the permissions helper
