What is podcasting?
• From Wikipedia:
• “Podcasting is the distribution of audio
or video ﬁles, such as radio programs or
music videos, over the internet using
either RSS or Atom syndication for
listening on mobile devices and personal
computers.”

Podcasting is growing
• FeedBurner now distributes 47,000 different
podcasts, which means there are more
podcasters than radio stations.

• The rate at which new podcasters emerge
on the scene has doubled in the last six
months.

10

Projections
• The Diffusion Group forecasts that the use
of podcasting among U.S. consumers is
growing at a compound annual rate of 101 %

• By 2010, 56.8 million Americans will be using
“time-shifted digital audio ﬁles” or podcasts

A natural evolution

• CMFAudio (CMF-based)
• ATAudio (Archetypes-based)
• Plone4ArtistsAudio (Zope 3)

19

Why Zope 3?
• Usability - user uploads File and system
ﬁgures out how to handle it. Easier with Z3

• Pluggability - easily extend to support other
formats besides MP3 and Ogg

• Reusability - abstracting the code into Zope
3 components means it is easier to reuse

Challenges of large ﬁles
Uploading and Storing

45

Pain points

• Uploading large ﬁles is tedious
• ZODB is currently not designed to store
large ﬁles

46

Making upload less tedious

• WebDAV/FTP
• gives you progress bar but it can be buggy
• PloneJUpload - java applet
• not all browsers have Java support

47

Preferred upload solutions
• Zip file
• uncompress zip file on server
• Tramline
• bypass Zope and use Apache
• lovely.widget
• Flash-based file upload widget
48

Import Zip ﬁle / PloneJUpload

49

Why store media on FS?

• Avoid ZODB bloat
• Expose to 3rd party streaming software
• Easier to backup or move to another system
• Transcode video ﬁles

50

Alternative storage layers
• FileField(‘mediaﬁle’, storage=...)
• ExternalStorage
• used on plone.org’s PloneSoftwareCenter
• FileSystemStorage
• used by Andreas Jung for large media project

51

Alternative ﬁle ﬁeld
• BlobFile
• dependent on blob
• ATTramline
• dependent on Tramline
• AttachmentField
• new version has FlexStorage
• PLIP #154 - Large File Handling
