  • description – Description of the entry.
  • isSummary – If the description should be used as content or summary.
Returns:

The entries description.

enclosure(url=None, length=None, type=None)

Get or set the value of enclosure which describes a media object that is attached to the item. This is a RSS only value which is represented by link(rel=enclosure) in ATOM. ATOM feeds can furthermore contain several enclosures while RSS may contain only one. That is why this method, if repeatedly called, will add more than one enclosures to the feed. However, only the last one is used for RSS.

Parameters:
  • url – URL of the media object.
  • length – Size of the media in bytes.
  • type – Mimetype of the linked media.
Returns:

Data of the enclosure element.

guid(guid=None)

Parameters:guid – Id of the entry.

Parameters:id – New Id of the entry.
Returns:Id of the entry.

Get or set link data. An link element is a dict with the fields href, rel, type, hreflang, title, and length. Href is mandatory for ATOM.

This method can be called with: - the fields of a link as keyword arguments - the fields of a link as a dictionary - a list of dictionaries containing the link fields

A link has the following fields:

  • href is the URI of the referenced resource (typically a Web page)

  • rel contains a single link relationship type. It can be a full URI, or one of the following predefined values (default=alternate):

    • alternate an alternate representation of the entry or feed, for example a permalink to the html version of the entry, or the front page of the weblog.
    • enclosure a related resource which is potentially large in size and might require special handling, for example an audio or video recording.
    • related an document related to the entry or feed.
    • self the feed itself.
    • via the source of the information provided in the entry.
  • type indicates the media type of the resource.

  • hreflang indicates the language of the referenced resource.

  • title human readable information about the link, typically for display purposes.

  • length the length of the resource, in bytes.

RSS only supports one link with nothing but a URL. So for the RSS link element the last link with rel=alternate is used.

RSS also supports one enclusure element per entry which is covered by the link element in ATOM feed entries. So for the RSS enclusure element the last link with rel=enclosure is used.

Parameters:
  • link – Dict or list of dicts with data.
  • replace – Add or replace old data.
Returns:

List of link data.

The value can either be a string which will automatically be parsed or a datetime.datetime object. In any case it is necessary that the value include timezone information.

Parameters:published – The creation date.
Returns:Creation date as datetime.datetime

Get or set the rights value of the entry which conveys information about rights, e.g. copyrights, held in and over the entry. This ATOM value will also set rss:copyright.

This method will also set the rss:description field if it wasn’t previously set or contains the old value of summary.

Parameters:summary – Summary of the entries contents.
Returns:Summary of the entries contents.
title(title=None)
