Improved Syndication

Reported by: vangheem Owned by: vangheem
Priority: minor Milestone: 4.3
Component: Templates/CSS Version: 4.3
Keywords: Cc: hvelarde

Description (last modified by vangheem) (diff)

Proposer: Nathan Van Gheem
Seconder: David Glick


Currently, plone syndication is not very robust. Some of the current shortcomings include:

  • No way to customize how the RSS feed is rendered per content type
  • No way to disable showing author username on feed with out customizing the template
  • Syndication settings are not enabled by default.
  • Currently, most integrators utilize Products.basesyndication with Products.fatsyndication in order to have better syndication. Plone really needs this sort of functionality in core.
  • Data stored in unnecessary tool when it could be in registry
  • Should use annotation storage for feed settings


Update the current syndication framework in Products.CMFPlone.

  • Remove skin layer related rss and syndication settings--move to views.
  • Provide additional atom, itunes, feed format.
  • Be able to select which feed types are available.
  • Provide 4 OOTB feed types(rss 1.0, rss 2.0, atom, itunes)
  • Provide control panel to edit site feed settings
    • Be able to disable search feed(search_rss)
    • Be able to enable/disable syndication settings button portal action
    • Be able to enable/disable syndication link portal action
  • Implement feed rendering with adapters that can easily be overridden and customized by developers to provide customized feeds. This is similar to how Products.fatsyndication does syndication.
  • Have feed rendering respect "Allow anyone to view 'about' information" for author field in feed item so sites can prevent their user's usernames and information from being published.
  • All code will be in Products.CMFPlone, let's not make any new packages ;)
  • Migrate all syndication_information objects to annotation storage
  • Migrate portal_syndication tool to use registry, views and utilities


Initial implementation is done.

Missing migration yet and more tests.


Very little risk since we're staying backward compatible with the old /RSS urls.

There may be a little bit of risk to existing product developers that use Products.fatsyndication will need to be aware that core plone will supersede it.

Is there a buildout I can use to review your changes? I don't see much at  https://github.com/plone/buildout.coredev/tree/plip12908 (maybe you haven't pushed everything?) At the very least, please let me know which packages/branches to look at.

Oh, found it in the plips dir of the main 4.3 branch. :)

One cause for the flakiness of many solutions for rss/atom syndication is the rigidity of xml parsers.

If I were involved in implementation of syndication (which I'm not), I'd keep an eye on the emerging XML subset "MicroXML":

 NewsML is an IPTC backed media-type agnostic news exchange format standard for general news; NewsML is used by news aggregators like MSN to include content on their sites and also to distribute it ( e.g. MSNMoneyInvestFeed).

Other Open Source CMS, like  Drupal and  WordPress, already have support for NewsML feeds.

I think it could be a good idea to include this by default in Plone; we can work on it if you think it could be a valid enhancement.

  • Cc hvelarde added

hvelarde: This plip has been merged at this point. Are you still planning on providing the NewsML feed type or is that something I should look into implementing?
