FAIRsharing record for: FAIR Metric – I1 – Metadata - Database-level knowledge representation languages (syntactic)

This FAIRsharing record describes: ### What is being measured?

This metric evaluates whether there is a declared relationship (related to, implements or outputs) to a model/format from the hosting database for the provided identifier in the FAIRsharing registry, and that the associated model/format has a machine-readable syntactic structure as per FAIRsharing guidance (see support links).

### Why should we measure it?

I1 requires that metadata use a formal, accessible, shared and broadly applicable language for knowledge representation. The purpose of this principle is to ensure that metadata is expressed in a standardised format that can be interpreted and exchanged across systems. In this metric, the definition of syntactic and semantic formats follows the FAIRsharing guidance (see support links). This metric evaluates whether there is a declared metadata model or format that ultimately resolves to a basic representation format that is considered syntactic by the FAIRsharing registry. Note that all formats that match the guidance on semantic formats also fulfil the requirements for being syntactic formats.

Communities may wish to use this metric in conjunction with others that examine the precise format of the resolved metadata.

Note that, in order for this metric to function, tests must know the FAIRsharing database record URL/DOI so that FAIRsharing metadata may be retrieved. This can be done in a variety of ways, e.g. using the FAIRsharing API to find possible matches between the identifier and registered databases, hard coding the FAIRsharing record identifier, or expecting it to be provided as a second argument to the test.

本FAIRsharing记录阐述如下内容：
### 本指标的评估对象为何？
本指标用于评估：在FAIRsharing注册中心中，针对所提供的标识符，其托管数据库是否声明了与某一模型/格式存在关联（包括相关联、实现该模型/格式或输出该模型/格式），且该关联模型/格式符合FAIRsharing指南中定义的机器可读句法结构（详见支持链接）。

### 为何需要开展此项评估？
FAIR原则中的I1条款要求元数据需采用形式化、可访问、可共享且广泛适用的知识表示语言。该条款的核心目标在于确保元数据以标准化格式进行表述，从而能够在不同系统间被解读与交换。在本指标中，句法格式与语义格式的定义遵循FAIRsharing指南（详见支持链接）。本指标用于评估是否存在经声明的元数据模型或格式，其最终可解析为FAIRsharing注册中心认定为句法格式的基础表示格式。请注意：所有符合语义格式指南的格式，均同时满足句法格式的相关要求。

各相关社区可将本指标与其他用于核查解析后元数据精确格式的指标结合使用。

请注意：为使本指标正常运行，测试程序需知晓FAIRsharing数据库记录的URL或数字对象标识符（Digital Object Identifier，DOI），以便获取FAIRsharing元数据。实现方式包括但不限于：通过FAIRsharing应用程序编程接口（Application Programming Interface，API）查找标识符与已注册数据库之间的潜在匹配项、硬编码FAIRsharing记录标识符，或要求将其作为测试的第二个参数传入。
