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，它们是通过组合几个组件创建的。这些组件有各种类型，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，各种研究工作都集中在支持和改进组件驱动的软件开发过程的技术方面。然而，很少有人注意到它的法律的复杂性。这方面已经被广泛使用的开源组件（如Eclipse和Apache基金会的组件）的可用性复杂化，这些组件在商业和开源应用程序中使用。基于组件的应用程序的创建者必须频繁地将具有不同许可证（通常是商业许可证和开放源码许可证）的组件联合收割机组合起来，以创建具有自己的许可证的新软件应用程序。这些许可证中的每一个都将强加某些约束，这些约束应该由最终系统来遵守。随着时间的推移，组件（或最终系统）的许可证可能会发生变化，旧组件会被丢弃，新组件会被添加，因此有必要将许可证问题视为软件发展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）创建模型，抽象基于具有多个许可证的组件创建和发展系统的挑战和问题，以及2）解决和解决这些挑战的方法和技术。这包括：
