This relationship type belongs to the Business to Business Relationship Class.
This describes a situation where one label is (or was) a subsidiary of another label, during a given period of time. This should be used either to describe the fact a label is a subdivision of another one, or, through corporate aquisition of the former label, has become a subdivision of another one.
- The start date for buyouts is the date of the transaction from which the target label became a subsidiary of the other label. For wholly owned subdivisions, use the subdivision's creation date.
- The end date may be either the subdivision's end date, or the date of a later sellout/spin-off.
- Do not use this relation if the transaction concerns only the rights to reissue (part of) the label's catalog. The same goes when a label buys another one only for its catalog, reissuing the releases but dismantling the former label. Either case should instead use the Label Reissue Relationship Type.
- Do not use this advanced relationship to attempt to represent facts such as label A owning 0.5% shares in label B's parent corporation. MusicBrainz is not a corporate database, so keep it simple.
- Also, do not to break the hierarchy of labels. This should only link between a label and its immediately parent company, not between a label and its top-parent company (or another one somewhere in the scale between), though this may become complicated in some cases.
- More complex cases do happen, and labels may change hands a lot of times. Multiple parents for a single label during the same period of time is even possible, such as the case of "shared compilation companies".
