Description

The sequences define the c3s internal reference to an object, which is communicated to the web user.

Right now, there exist sequences for Artists and Creations. I assume, we should also define sequences for Releases, too?

  • Is an ordinary increment ok?
  • Should there be padding?
  • Any pre-/postfixes?

Exactly (suffixes are also possible).

The attributes of a sequence are

  • prefix (String)
  • suffix (String)
  • padding (Integer)

Something reasonable would be: perhaps a prefix for the sequence type (artists, creations, releases(?)) and a padding, which reflects the expected total number of objects. As these sequences are the "official" identifiers for the objects, their definitions are not technical, but administrative in nature.

yes.

agreed, it's what i had in mind with:

a00000012 r000003036 c00000064722

not sure about the numer of zeroes, i'd look at the stats of musicbrainz and discogs and make sure it won't need fixing in the next 100 years ;-)

From https://musicbrainz.org/statistics

Artists:   1,196,253
Releases:  1,779,175
Tracks:   22,211,592

So, what about a padding of 10 (10 billion - 1)? And big letters (better clarity)?

  • Artists: A##########
  • Releases: R##########
  • Creations: C##########

It's a bit of trouble to write that down, if needed, but would be save for quite a while.
