DiscogsFeeds

For years I've wanted Discogs to add support for artist and label specific RSS feeds so I could be notified of new releases.
This was recently implemented with the new "recent releases" section on each artist page.
However I still found myself wanting more control over exactly what the feeds contain, or the option to see all new releases on a given label.

So I've built a web service that leverages the Discogs API to provide filterable feeds for any label, artist, release or search query.
It supports not only Atom and RSS, but also JSON and BSON, meaning it could be used as a more natural way to consume Discogs data from JavaScript.

Getting Started

To begin with you'll need a Discogs API key which you can get here.
This key is used to access the Discogs API and is not stored in any way by my service.

Basic Usage

Once you have a key, you can request a feed, like so:

www.nathanbaulch.com/DiscogsFeeds/artist/Aphex Twin?api_key=[API_Key]

The default format returned is Atom, a common standard understood by most feed readers.
Now let's say you only want to see full albums. You can use the $format filter parameter:

www.nathanbaulch.com/DiscogsFeeds/artist/Aphex Twin?api_key=[API_Key]&$format=Album

All custom parameters have been prefixed with a dollar sign to prevent clashes with current and future Discogs API parameters.
If you want to request more than one format at a time you can simply add more $format parameters and they'll be logically OR-ed together:

www.nathanbaulch.com/DiscogsFeeds/artist/Aphex Twin?api_key=[API_Key]&$format=Album&$format=CD

The filter values also support asterisks wildcards so that, for example, you can match multiple formats like CD, 2xCD, 3xCD, etc in one filter:

www.nathanbaulch.com/DiscogsFeeds/artist/Aphex Twin?api_key=[API_Key]&$format=*CD

If you want to limit the results to actual release by the artist and not remixes they've done or track appearances, you can use the $type parameter:

www.nathanbaulch.com/DiscogsFeeds/artist/Aphex Twin?api_key=[API_Key]&$type=Main

Advanced Features

A special value-less $distinct parameter can be used if you want to combine all releases with the same artist and title:

www.nathanbaulch.com/DiscogsFeeds/artist/Aphex Twin?api_key=[API_Key]&$distinct

This helps to cut down on duplicate releases on different labels, just like Discogs does with "master" release pages.

Other content formats can be requested by assigning the "f" parameter values such as rss, json, bson or xml:

www.nathanbaulch.com/DiscogsFeeds/artist/Aphex Twin?api_key=[API_Key]&f=json

Due to a limitation in the technology I've built this service with, non-ASCII characters are not allowed in URLs.
To work around this, a $name parameter can be used with standard Unicode escape codes when requesting artists or labels with non-ASCII characters:

www.nathanbaulch.com/DiscogsFeeds/artist?$name=Trentemøller&api_key=[API_Key]&$distinct

Labels, specific releases and search queries can also be requested and filtered using the conventions outlined in the official Discogs API documentation.
Please refer to this documentation for information on the available fields and their potential values.
