Business process modelling languages typically enable the representation of business process models by employing (graphical) symbols. These symbols can vary depending upon the verbosity of the language, the modeling paradigm, the focus of the language, and so on. To make explicit the different constructs and rules employed by a specific language as well as bridge the gap across different languages, meta-models have been proposed in literature. These meta-models are a crucial source of knowledge on what state-of-the-art literature considers relevant to describe business processes. Moreover, the rapid growth of techniques and tools that aim at supporting all dimensions of business processes and not only its control flow perspective, as for instance data and organisational aspects, makes even more important to have a clear idea, already at the conceptual level, of the key process constructs. The goal of this work is to provide the first extensive systematic literature review (SLR) of business process meta-models. This SLR aims at answering research questions concerning: (i) the kind of meta-models proposed in literature; (ii) the recurring constructs they contain; (iii) their purposes; and (iv) their evaluations. Thirty-six papers were selected and evaluated against four research questions. The results indicate the existence of a reasonable body of work conducted in this specific area, but not a full maturity. In particular, while traditional paradigms towards business process modelling, and aspects related to the business process control flow seem to be well present, novel paradigms and aspects related to the organisational, data and goal-oriented aspects of business processes seem to be still under-investigated.

我的流程模型由什么组成？BPM 中元模型的系统文献综述

业务流程建模语言通常能够通过使用（图形）符号来表示业务流程模型。这些符号可以根据语言的详细程度、建模范式、语言的重点等而有所不同。为了明确特定语言采用的不同结构和规则，并弥合不同语言之间的差距，文献中提出了元模型。这些元模型是了解最先进文献认为与描述业务流程相关的知识的重要来源。此外，旨在支持业务流程所有维度的技术和工具的快速增长，而不仅仅是其控制流视角，例如数据和组织方面，使得拥有一个清晰的想法变得更加重要，已经处于关键流程构造的概念级别。这项工作的目标是提供业务流程元模型的第一个广泛的系统文献综述 (SLR)。该 SLR 旨在回答有关以下方面的研究问题：(i) 文献中提出的元模型类型；(ii) 它们包含的重复结构；(iii) 他们的目的；(iv) 他们的评价。三十六篇论文被选中并针对四个研究问题进行评估。结果表明，在该特定领域存在合理的工作体系，但尚未完全成熟。特别是，虽然传统的业务流程建模范式和与业务流程控制流相关的方面似乎很普遍，但与组织、
