With the rise of podcasting and sharing multimedia content online, there is a growing need for tools that help content producers publish multimedia to their website. We will discuss the Plone4Artists suite of products which streamline the process of publishing audio, videos and images on your Plone site. After installing the Plone4Artists add-ons, Plone will be able to extract the metadata from uploaded audio, video and image files, make this metadata editable and searchable and playback the audio/video files in the browser. Using RSS syndication, you can also make collections of this multimedia content available to your users as a podcast/vodcast/photocast feed. We will also discuss some of the challenges of handling large files in Plone, including tools to improve the uploading process and how to store large files outside of the ZODB and instead on the file system.
