Well...

https://en.wikipedia.org/wiki/Digital_identity
  ISO/IEC 24760-1 defines identity as "set of attributes related to an entity"

So lets say GRIDS stores for an entity one or more identifier entries. Each identifier
entry has data like locators associated as well as some authenticator like a cert owned
by the entity.

Entity connects to grids, "asserts its identity" by a cryptographic proof of ownership
operation for the authenticator (eg: cert) and then it can change the data, eg: locators
associated with the identifier entry of the entity.

In this example, i guess (identifier, authenticator) is one identity of the the entity.
Maybe someone wants to spend 118 CHF on that ISO standard to get the IDEAS terminology
in compliance with it ? ;-))

How many disagreement points do i score ?
