Bridge request: Web archive for Mailman instance

Bridge request

As a heavy user of RSS-bridge, I would like to have an RSS feed generator that can parse the web-based archives of mailing lists implemented with GNU Mailman.

General information

Given a GNU Mailman powered mailing list such as the IETF Calsify list, I would like to plug the URL for the web archive (https://mailarchive.ietf.org/arch/browse/calsify/) into a field of RSS-bridge and get an RSS feed of posts sent to/through the mailing list.

The kind of information I would like to see generated by such a feed:

• URL to a new post in the archive.

• Subject line of a new post in the archive.

• To and From lines of a new post in the archive.

• Body of a new post in the archive.

• Links to previous and next posts in the discussion thread (if present).

• How should the information be displayed/formatted?

<item>
<title> [ subject line goes here ] </title>
<link>[ link to the post in the archive]</link>
<pubDate>[ date the message was sent] </pubDate>
<author>[ contents of From: line]</author>
<guid isPermaLink="true">[ URI to post in the archive ]</guid>
<description>
[ contents of From: line]
[ contents of To: line]
[ contents of Subject: line]
[ contents of date and time line]
[ body of message ]
[ link to previous post in thread, if applicable ]
[ link to next post in thread, if applicable ]
</description>
</item>

• Title
• URI (link to the original article)
• Author
• Timestamp
• Content (the content of the article)
• Enclosures (message attachments?)
• Categories (categories, tags, etc...)

Options

• Limit number of returned items
  • Default limit: 10
• Load full articles
  • Cache articles (articles are stored in a local cache on first request): Doesn't seem useful given how active some lists are.
• Balance requests (RSS-Bridge uses cached versions to reduce bandwith usage)
  • Timeout (default = 5 minutes, max = 24 hours): 5 minutes

Start by inspecting the example GNU Mailman archive at https://mailarchive.ietf.org/arch/browse/calsify/ and compare its pages with the requested RSS-Bridge output. Done means producing a feed with post links, subjects, author, timestamp, content, attachments, thread navigation where available, and the stated item-limit and caching options.
