The success of a software system depends critically on how well it reflects and adapts to stakeholder requirements. Traditional development methods often frustrate stakeholders by creating long latencies between requirement articulation and system deployment, especially in large scale systems. One source of latency is the maintenance of policy decisions encoded directly into system workflows at development time, including those involving access control and feature set selection. We created the Policy Driven Development (PDD) methodology to address these development latencies by enabling the flexible injection of decision points into existing workflows at runtime, thus enabling policy composition that integrates requirements furnished by multiple, oblivious stakeholder groups. Using PDD, we designed and implemented a production cyberinfrastructure that demonstrates policy and workflow injection that quickly implements stakeholder requirements, including features not contemplated in the original system design. PDD provides a path to quickly and cost effectively evolve such applications over a long lifetime.

软件系统的成功主要取决于它对涉众需求的反映和适应程度。传统的开发方法经常在需求表述和系统部署之间造成长时间的延迟，特别是在大型系统中，从而使涉众感到沮丧。延迟的一个来源是在开发时直接编码到系统工作流中的策略决策的维护，包括那些涉及访问控制和特性集选择的决策。我们创建了策略驱动开发(PDD)方法，通过支持在运行时将决策点灵活地注入到现有工作流中来处理这些开发延迟，从而支持策略组合，集成由多个无关的涉众组提供的需求。使用PDD，我们设计并实现了一个产品网络基础设施，它演示了快速实现涉众需求的策略和工作流注入，包括原始系统设计中未考虑到的功能。PDD提供了一种途径，可以在较长的生命周期内快速且经济有效地发展此类应用程序。

A Compositional Event & Time-Based Policy Model 组合事件&基于时间的策略模型

Policies are increasingly used to govern the behaviour of complex distributed systems. Most policy models that allow policy composition, to address the complexity of policies, are only concerned with structural composition. In this paper we argue that it is natural to compose policies also along the temporal axis, i.e. express policies that can dynamically change over time or on the occurrence of events. We present a dynamic policy frame-work that has a sound semantics in Interval Temporal Logic and allows both structural and temporal composition. We provide examples of authorisation, delegation and obligation policies that can be activity-based, state-based or historybased, i.e. expressing decisions on the history of execution. Examples for the composition of policies show how the framework can be used to express policies for systems that operate in an environment that is characterised by uncertainty. Finally tool-support for the specification and analysis of dynamic policies is presented.
策略越来越多地用于管理复杂分布式系统的行为。为了解决策略的复杂性，大多数允许策略组合的策略模型只关注结构组合。在本文中，我们认为沿时间轴组合策略是很自然的，即表示可以随时间或事件发生而动态变化的策略。我们提出了一个动态策略框架，它在区间时间逻辑中具有良好的语义，并允许结构和时间组合。我们提供了授权、委托和义务策略的示例，这些策略可以是基于活动的、基于状态的或基于历史的，即根据执行历史来表达决策。策略组合的示例显示了如何使用框架来表示在不确定环境中运行的系统的策略。最后给出了动态策略规范和分析的工具支持。
