OPML in FreshRSS

FreshRSS supports the OPML format to export and import lists of RSS/Atom feeds in a standard way, compatible with several other RSS aggregators.

However, FreshRSS also supports several additional features not covered by the basic OPML specification. Luckily, the OPML specification allows extensions:

An OPML file may contain elements and attributes not described on this page, only if those elements are defined in a namespace.

and:

OPML can also be extended by the addition of new values for the type attribute.

FreshRSS OPML extension

FreshRSS uses the XML namespace https://freshrss.org/opml to export/import extended information not covered by the basic OPML specification.

The list of the custom FreshRSS attributes can be seen in the source code, and here is an overview:

HTML+XPath

ℹ️ XPath 1.0 is a standard query language, which FreshRSS supports to enable Web scraping.

The following attributes are using similar naming conventions than RSS-Bridge.

Miscellaneous

Dynamic OPML (reading lists)
