Summary: Obliq is a distributed, object-based programming language. In Obliq, the migration of an object is proposed as creating a clone of the object at the target site, whereafter the original object is turned into an alias for the clone. Obliq has an only informal semantics, so there is no proof that this style of migration is correct, i.e., transparent to object clients. In this paper, we focus on Øjeblik, an abstraction of Obliq. We give a \(\pi\)-calculus semantics to Øjeblik and we use it to formally prove the correctness of object surrogation, an abstraction of object migration.
