Abstract
Multimedia objects distributed in networks are concurrently manipulated by multiple transactions in applications like co-authoring systems. Not only state but also quality of service (QoS) of object is changed through methods. We define new types of conflicting and exclusive relations on methods to serialize transactions and to realize exclusive manipulation of an object by taking into account QoS change in addition to state change. We discuss a protocol for locking objects and serializing transactions with respect to the QoS-based relations.
