Will an imported blog post be updated if the original blog post changes?



I imported posts from a blog into a Blog Stream using RSS. If I make a change to a post in the original blog, will the corresponding Item in Uberflip be updated as well?



In general, yes: if you import a blog post into Uberflip and then subsequently edit that post in the source blog, the post in Uberflip will also be updated automatically. For this to happen, the following conditions must be met:

  • The blog Item must not be edited in Uberflip: as soon as any changes are made to an imported blog Item in Uberflip, it is considered distinct from the original blog post, and the link between them is severed permanently
  • The original blog post must still be available in the RSS feed: once the original blog post drops off the RSS feed, we are no longer able to query it for updates
  • The original blog post must be within the most recent 200 items in the RSS feed: Even if the original blog post is still in the RSS feed, Uberflip will only check the most recent 200 items for updates

Note also that this applies only to modifying the original post. If you delete (rather than change) the original blog post, the imported Item will not be deleted, and will remain in Uberflip.

What about other types of Items?

The same principle applies to Items in all other types of Source Streams as well, e.g. Video, Social, and Docs (except Flipbooks): in general, modifying the source content will modify the imported Item in Uberflip, unless it has been modified in Uberflip first.



If you're interested in the technical details, here's how it works:

When you import a blog post via RSS, Uberflip takes the unique identifier of the post (the GUID) and saves it to the External ID field of the corresponding Blog Item. This shared identifier is what links the original post with the Uberflip Blog Item.

In ca. 20-minute intervals, Uberflip runs an automatic job that inspects the RSS feed and compares the original posts with the Blog Items. If the Date Modified value on an original blog post is more recent than on the Blog Item with the same identifier, we assume that the original post has been modified. In such cases, Uberflip will update the Item's content, Tile thumbnail and Date Modified value by re-importing from the RSS feed.
