Welcome to WebmasterWorld Guest from 18.104.22.168
I've reading about RSS recently and stumled across Atom feeds. I've tried to research more. Many say that Atom is more advanced and offers more options that RSS.
Now I'm trying to understand those content and summary elements in Atom feed that are analog to RSS <description>
I've read that Atom's <summary> element is for non-textual information. But I didn't find anywhere about <content> element.
So what can I put in both? Can I put text, CDATA, images, videos, MP3 in <summary>?
Then what about <content>? Can I put all the same into <content>? Then what's the point of having both?
For example, if it's an article, then the summary would be a summary of the article (or first few lines), and the content would be the article.
The reader application could show the summary, the content, or both.
