A promising approach to managing business operations is based on <i>business artifacts</i>, a.k.a. <i>business entities</i> (<i>with lifecycles</i>). These are key conceptual entities that are central to guiding the operations of a business, and whose content changes as they move through those operations. An artifact type includes both an <i>information(More)
We formalize and study business process systems that are centered around "business artifacts", or simply "artifacts". Artifacts are used to represent (real or conceptual) key business entities, including both their data schema and lifecycles. The lifecycle of an artifact type specifies the possible sequencings of services that can be applied to an artifact(More)
Business process management, workflow, and case management are critical technologies for managing collections of services, including human activities, to support business operations. One way to manage business operations is based on business entities with lifecycles (BEL’s) (a.k.a. business artifacts), i.e., key conceptual entities that are central to(More)
In this paper, we study the problem of data integration in P2P systems. Differently from the traditional setting, data integration in these systems is not based on the existence of a global view. Instead, each peer exports data in terms of its own schema, and information integration is achieved by establishing mappings among the various peer schemas. We(More)

Business entities with lifecycles (BEL’s) (a.k.a. business artifacts) are used to model conceptual entities that are central to guiding the operations of a business, and whose content changes as they move through those operations. The recently introduced Guard-StageMilestone (GSM) meta-model for BEL lifecycles is declarative in nature, and allows concurrent(More)
Business artifacts (BAs, or artifacts) are used to model conceptual entities that are central to guiding the operations of a business, and whose content changes as they move through those operations. The recently introduced Guard-Stage-Milestone (GSM) meta-model for artifact lifecycles is declarative in nature, and allows concurrent execution of(More)
Considering a broad definition for service contracts (beyond web services and software, e.g. airline<lb>tickets and insurance policies), we tackle the challenges of building a high performance broker in<lb>which contracts are both specified and queried through their temporal behavior. The temporal<lb>dimension, in conjunction with traditional relational(More)
