What happened in Discogs in September 2018?

Continuing with data from September 2018: what happened then? If you don't already know the format, please read the previous post first.

Release statistics

So far the data has been very consistent and September 2018 is not an exception. I looked at the dump file with data covering September 1 - 30 2018. This dump file has 10,335,691 releases, whereas the previous one had 10,222,636 releases. That means 113,055 releases more. Of those:
  • 9,727,367 releases stayed the same
  • 491,702 releases were changed
  • 116,622 releases were added
  • 3,567 releases were removed from the database
  • 164 releases had status Draft, Deleted or Rejected
  • 11 releases that were not Accepted were in both dumps
  • 2 releases were moved from Draft to Accepted
And, again, the charts look very similar when compared to previous months:


What I personally find interesting is that September is when Discogs has its SPIN (September pledge initiative) when people are encouraged to add more releases to the database. The wrap up blog post about SPIN 2018 is raving about it being a big success but that is actually not what I see in the data because to me it looks like a very normal month in Discogs. Lies, damned lies and statistics.

What is also odd is that I get different numbers: Discogs says that 138,000+ releases were added but that is, again, not what I see in the data, so either they are looking at different data (which I would find odd) or they have a different definition of what a "release" actually is and also include the so called "master releases" which are more like overview pages of all different releases.

The data doesn't lie, plus I actually have the scripts to prove it.

Smells

It all looks very much like the other months: there were 1986 errors in the releases added in September, a bit over half of the errors are for label codes, a quarter SID code related, and the rest is the same as in previous months.

SID codes (part 1)

One thing that I only learned about after using Discogs is the so called Source Identification Code, or SID. These codes were introduced in 1994 to combat piracy and to find out on which machines a CD was made. It was introduced by Philips and adopted by IFPI, and specifications are publicly available which clearly describe the two available SID codes (mastering SID code and mould SID code). Since quite a few months Discogs has two fields available in the " Barcode and Other Identifiers " (BaOI) section: Mould SID code Mastering SID code A few questions immediately popped up in my mind: how many releases don't have a SID field defined when there should be (for example, the free text field indicates it is a SID field)? how many releases have a SID field with values that should not be in the SID field? how many release have a SID field, but a wrong year (as SID codes were only introduced in 1994) how many vinyl releases have a SID code defined (which is impossi...

SPARS codes (part 1)

Let's talk about SPARS codes used on CDs (or CD-like formats). You have most likely seen it used, but maybe don't know its name. The SPARS code is a three letter code indicating if recording, mixing and mastering were analogue or digital. For example they could look like the ones below. There is not a fixed format, so there are other variants as well. Personally I am not paying too much attention to these codes (I simply do not care), but in the classical music world if something was labeled as DDD (so everything digital) companies could ask premium prices. That makes it interesting information to mine and unlock, which is something that Discogs does not allow people to do when searching (yet!) even though it could be a helpful filter. I wanted to see if it can be used as an identifier to tell releases apart (are there similar releases where the only difference is the SPARS code?). SPARS code in Discogs Since a few months SPARS is a separate field in the Discogs ...

Country statistics (part 2)

One thing I wondered about: for how many releases is the country field changed? I looked at the two most recent data dumps (covering February and March 2019) and see where they differed. In total 5274 releases "moved". The top 20 moves are: unknown -> US: 454 Germany -> Europe: 319 UK & Europe -> Europe: 217 unknown -> UK: 178 UK -> Europe: 149 Netherlands -> Europe: 147 unknown -> Europe: 139 unknown -> Germany: 120 UK -> US: 118 Europe -> Germany: 84 US -> UK: 79 USA & Canada -> US: 76 US -> Canada: 65 unknown -> France: 64 UK -> UK & Europe: 62 UK & Europe -> UK: 51 France -> Europe: 51 Saudi Arabia -> United Arab Emirates: 49 US -> Europe: 46 unknown -> Japan: 45 When you think about it these all make sense (there was a big consolidation in Europe in the 1980s and releases for multiple countries were made in a single pressing plant) but there are also a few weird changes:...
