Despite the fact that JSON is currently one of the most popular formats for exchanging data on the Web, there are very few studies on this topic and there is no agreement upon a theoretical framework for dealing with JSON. Therefore in this paper we propose a formal data model for JSON documents and, based on the common features present in available systems using JSON, we define a lightweight query language allowing us to navigate through JSON documents, study the complexity of basic computational tasks associated with this language, and compare its expressive power with practical languages for managing JSON data.

JSON：数据模型和查询语言

尽管JSON是当前在Web上交换数据的最流行的格式之一，但有关此主题的研究很少，并且在处理JSON的理论框架上也没有共识。因此，在本文中，我们提出了一个用于JSON文档的正式数据模型，并基于使用JSON的可用系统中存在的常见功能，我们定义了一种轻量级的查询语言，允许我们浏览JSON文档，研究与之相关的基本计算任务的复杂性这种语言，并将其表现力与用于管理JSON数据的实用语言进行比较。
