Recent contributions in the field of technology roadmapping often aim to apply various numerical models and tools to facilitate the roadmapping process and enrich its outcomes. This trend resulted in the emergence of so-called model-based technology roadmapping. We consider it as the future development of the traditional document-based paradigm. One of the general approaches to support the model-based roadmapping is to develop a roadmap's metamodel that would define it independently from the application context and link it to the existing roadmapping literature. In this paper, we attempt to create such a metamodel by generalizing and formalizing existing document-based roadmaps. We validate our metamodel via reproducing three very different roadmaps from the literature, not included in the set of roadmaps from which the metamodel was created, using the novel formal approach. The fact that these roadmaps were reproduced using the proposed metamodel indicates its applicability to many classes of real roadmaps. The results of this work seem beneficial for architects of the software tools for roadmapping and for the regular participants of roadmapping sessions.

最近在技术路线图领域的贡献通常旨在应用各种数值模型和工具来促进路线图过程并丰富其结果。这种趋势导致了所谓的基于模型的技术路线图的出现。我们认为它是传统的基于文档的范式的未来发展。支持基于模型的路线图的一般方法之一是开发路线图的元模型，该元模型将独立于应用程序上下文对其进行定义，并将其链接到现有的路线图文献。在本文中，我们试图通过概括和形式化现有的基于文档的路线图来创建这样一个元模型。我们通过从文献中复制三个截然不同的路线图来验证我们的元模型，这些路线图未包含在创建元模型的路线图集中，使用新颖的形式方法。这些路线图是使用提议的元模型重现的事实表明它适用于许多类别的真实路线图。这项工作的结果似乎对路线图软件工具的架构师和路线图会议的常规参与者有益。
