Discovery Channel Feed Problem

Post by markmorgan » Wed Mar 15, 2006 2:49 pm

The news feed from the Discovery Channel causes a problem for Awasu

http://dsc.discovery.com/news/news.rss

Awasu keeps thinking items on the feed are new items and adds another item to the channel rather than spotting it as an update to the previous item or an unchanged item which most of them are.

FeedValidator says the guid is not sufficiently unique - could this be it? Is it the publisher - if they are changing the guid each time they refresh the feed (I'm not sure they are... just grasping at straws) would this cause the problem?

Their GUID's are not very good and yes, if they keep changing then Awasu will interpret that as receiving new items.

I'll keep an eye on this feed and see what it's doing.

Yup, they're changing the GUID's. A seriously not-bright thing to be doing :-)

You can use the SaveChannelFeeds channel hook to save a copy of each feed XML as the channel updates to see it happening.

I emailed this to the Discovery Channel tech support. Whilst I didn't receive a reply their feed has changed and no longer suffers from the problem. The new feed can be found here

Result! :D
