A comment is that 'control' might imply more than can be delivered for 
'identity'; to the   degree that identity consists in what other 
people think of us and we can't control that part. I also find the 
'expressed' slightly confusing (about what is expressed -- the model, 
the identity, or the thing) and the statement seems to works fine 
without it. So perhaps:

SSI: An identity model that allows an individual or organization to 
hold the primary control over their own identities, or the identity of 
a thing, through the use of decentralized identifiers and digital
