Implemented and in Roller trunk, ready for Roller 5.0 release


University project Sept 08- May 09



You can upload any type of content to a Roller weblog and include that content on weblog entries as images or Podcasts, but the tools for doing so are lacking. The interface that allows you to browse your file uploads does not display thumbnails, it is not sortable and not pagable. Once you have uploaded an image or Podcast, you have to cut and paste the URL into your blog post. This project will replace that old File Upload user interface with a more interactive and modern UI for browsing and choosing media and automatically adding the correct HTML markup to blog entries.


Basic requirements:

Replace Roller's existing File Upload pages with:

  • Sortable, searchable, hierarchical and tabular display of uploaded files
  • Auto-generate and display small thumbnails for all images
  • Ability to specify metadata for uploads including title, filename, content-type and tags
    • Support for new metadata in Roller's AtomPub implementation
  • Support for media blogging features from both Weblog Entry Editor and File Uploads page:
    • Ability to add to any entry an enclosure (i.e. a podcast)
    • Ability to add to any entry images with optional title and thumbnail
  • Support for external media files
