The Edition Feed

Pugpig supports RSS feeds for creating both articles (see more here) as well as editions/magazines and timelines.

It is common to use this for editions in particular. It is quite rare to use this feature for timelines as they are often set up as part of onboarding. However, if your app does frequently change its timelines, it may be useful.

For a more in depth look at our feed importing process and our article feed specification, see here.

Standard elements overview

This is an overview of required elements in our feed. You can view these in an example feed below:

• <rss:guid> for the edition key, which should match the In App Purchase code and your entitlement system if relevant. Specific additional categories can be sent if the IAP codes and entitlement codes differ.
• <rss:title> for the edition title.
• <dcterms:issued> for the publication date of the issue, which is user facing.
• <rss:description> for the summary of the edition.
• <media:content url="https://www.pugpig.com/wp-content/uploads/edition-cover1.png" width="1040px" type="image/jpeg" /> for the cover image.
• <category> a collection tag which should also be included on any articles that are part of this edition. We may also map other fields (such as the <guid> element) as a tag, since it can be used as an identifier for the edition. It must be unique to this edition.
• <pubDate> this is the non-visible publish date of the edition, representing when it is published in our CMS. Usually this will be when the edition is first added to the feed. This is not user facing.
• <atom:updated> this is used to check for when the edition is updated in the feed.

Additional tags can be added to your RSS feed in order to map to information from your RSS feed to fields in Express.
