I made a thread about this a while back: > [@Alternate CD matrix/runout inscriptions: enough for a new release?](https://community.metabrainz.org/t/alternate-cd-matrix-runout-inscriptions-enough-for-a-new-release/79829): > > I’ve been wondering about this for years, but now it’s come to a head. Discogs will often have multiple versions of the same release with the only thing separating them being things like matrix/runout inscriptions. Recently I got ahold of a repressing of [this album](https://musicbrainz.org/release/265af347-31f0-45c8-b088-b236f25df6dd) and it looks visually identical to the original 1997 version, only that the inner matrix on each disc has different inscriptions. Is this enough to qualify for a new release? I’ve already gone ahead and attached Disc IDs; if I have to… Adding a data field for SID codes or other manufacturer identifiers might be a good idea, but it would require a schema change (which could take years to implement). --- _[View the full topic](https://community.metabrainz.org/t/adding-matrix-and-sid-information-to-releases/456479)._
