About OPML

Outline Processor Markup Language — nested outlines & feed lists.

OPML is an XML format for exchanging outlines: nested lists of items with attributes. It's most commonly used to export and import RSS/Atom feed subscriptions between readers, and by outlining tools. Our viewer parses the XML and renders the outline as a collapsible tree.
