Daniel Hazelton <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] Status|RESOLVED |REOPENED Resolution|INVALID | --- Comment #2 from Daniel Hazelton <[email protected]> 2009-05-30 20:41:48 UTC --- Resolving this bug as "invalid" is not correct. Yes, the <guid> tag is not required, but then, only the <title>, <link> and <description> tags are listed as required by the specification. "This “Global Unique Identifier” allows you to republish or update specific items without duplicating these items in an aggregator. If you change an item without using the <guid> element, then the aggregator has no way of determining that the new item is replacing an old item. In that case, the aggregator will retain the old item and the new item, forcing the user to read it twice. If the <guid> element exists (and is the same as a previous item’s <guid>) then the aggregator can (at the users option) replace the old item with the new one. If the user has not read the item yet, then all they will see is the updated item. If they have read the old item already, then they can optionally read the update or ignore it." -- http://www.feederreader.com/TechnicalGuides/RSS_Basic.html That is referenced from the current spec, which is apparently housed here: http://cyber.law.harvard.edu/rss/rss.html In other words... Without <guid> an "aggregator" has no way to determine whether an individual <item> is new or if it has been seen before. So while not required by the spec, not including it actually is a bug. No major feed that I have been able to find - and that claims to be RSS 2 - omits the <guid> tag. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
