1) The document discusses issues related to reconciling contractual concerns when composing web services from different providers. Each service may have different contract terms covering areas like QoS, business, legal, and intellectual property. 2) Existing works mainly focus on contract specification but do not address how to combine and reconcile contracts from multiple services. Real-world scenarios involve complex interactions between non-uniform contract specifications. 3) The paper raises several open questions around representing contracts using a common language, managing contracts separately from service descriptions, enabling automated contract negotiation and compatibility checking, and monitoring legal/IP terms for dynamic web services.
