LSIDs are particularly useful when that there is more than one metadata provider that a given authority knows about, where the authority has no control over or knowledge of the metadata provided by these third-parties [1]. In complete contrast to both of these is the case where a user like me, has no intent to publish any documents on the web, but requires a stable identifier to make statements about things. Sure, HTTP URIs can be used as identifiers, but why would I mint arbitrary HTTP URIs when I can use a scheme that has no resolution protocol implicitly or explicitly associated with it? -=Michel=- [1] Personal communication with Mark Wilkinson
