Most large software applications are not built from scratch; instead, they are created by combining several components. These components are of various types, such as libraries, database management systems, stand-alone programs, and network services. Over the last decade, various research efforts have focused on the technical aspects of supporting and improving component-driven software development processes. However, little attention has been directed toward its legal complexities. This aspect has been complicated by the availability of widely-used open source components (such as those of the Eclipse and the Apache Foundations) that are used in both commercial, and open source applications. The creators of component-based applications must frequently combine components with differing licenses (often commercial and open source) to create a new software application with its own license. Each of these licenses will impose certain constraints that should be honoured by the resulting system. Over time the licenses of components (or the resulting system) might change, old components dropped, and new ones added, making it necessary to consider licensing issues as another important concern of the software evolution and maintenance cycle. The main objectives of this research program are 1) to create models that abstract the challenges and issues of creating and evolving systems based on components with multiple licenses, and 2) methods and techniques to address and solve these challenges. This includes:

大多数大型软件应用程序不是从头开始构建的；相反，它们是通过组合多个组件来创建的。这些组件具有多种类型，例如库，数据库管理系统，独立程序和网络服务。在过去的十年中，各种研究工作集中在支持和改善组件驱动的软件开发过程的技术方面。但是，很少关注其法律复杂性。在商业和开源应用程序中使用的广泛使用的开源组件（例如Eclipse和Apache基金会的基础）的可用性使这一方面变得复杂。基于组件的应用程序的创建者必须经常将组件与不同的许可（通常是商业和开源）相结合，以创建具有自己许可证的新软件应用程序。这些许可中的每一个都将施加某些约束，应由结果系统兑现。随着时间的流逝，组件（或结果系统）的许可证可能会更改，旧组件掉落并添加了新的组件，因此有必要将许可问题视为软件演化和维护周期的另一个重要问题。该研究计划的主要目标是1）创建基于具有多个许可证组件的组件以及2）解决和解决这些挑战的方法和技术的模型，以使创建和不断发展的系统的挑战和问题。这包括：
