LinguaPlone

• Shows only content in the same language or neutral

• Filters content from other languages

Video in the Rapucation Site

• Don’t serve it from Plone

• It is stored in Plone (on the filesystem)

• Students can upload high res versions in any format for the instrumental and full sung version

Use a Streaming Provider

• Convert it to one default format and size

• Upload it to ftp.streamingprovider.com

• Update the song on the plone site with the correct video http-url

params = urllib.urlencode( {"status": status, "mtype" : movie_type, "file" : filename } )set_url = auth_song_url + "/@@set_conversion_status?" + paramsset_result = urllib.urlopen(set_url).read()

contentrules

• contentrules are great

• two components Filters and Actions

• check plone.app.contentrules for the basic examples

• Add small blocks of functionality

• one .py and a tests file is all there is to it

• reuse

• Been online for a year, next development cycle on account creation and management, it’s been proven now to work.

• Plone in eduction = cool !
