FAIRsharing record for: FAIR Metric – I3 – Metadata – Qualified References to Versioned Records

This FAIRsharing record describes: I3 requires that (meta)data include qualified references to other (meta)data. The purpose of this principle is to ensure that digital objects are connected to the wider research ecosystem through explicit, semantically defined relationships. The existing generic I3 metric evaluates identifier references that have different domains from the root domain of the input identifier. However, this approach is insufficient for many resources (e.g. institutional repositories), where meaningful relationships may occur within the same domain and must therefore be identified through explicitly defined relationship types rather than domain comparison alone.

This metric evaluates whether the metadata retrieved upon identifier resolution **contains at least one qualified, semantically defined link to another version of the repository record**. Implementations of this metric should test for:

* A qualified relationship indicating another version of the repository record (e.g. previous version, newer version, or alternative DOI version), expressed using defined relationship type(s).
* The relationship must explicitly describe the version connection and must not represent other types of relationships such as supporting files associated with the record.

A repository record will pass this metric if at least one explicitly defined version relationship is present in the metadata.

本FAIRsharing记录阐述如下内容：I3原则要求（元）数据需包含对其他（元）数据的合格引用。该原则的宗旨在于确保数字对象可通过明确、语义化定义的关联关系，接入更广泛的科研生态系统。现有通用I3指标会评估与输入标识符根域分属不同域的标识符引用。但该方法对诸多资源（如机构知识库）而言并不充分——此类场景中，有效关联可能存在于同一域内，因此需通过明确定义的关联类型而非仅依赖域对比来识别此类关联。

本指标用于评估：通过标识符解析获取的元数据，是否至少包含一条针对该知识库记录其他版本的、合格且语义化定义的关联链接。该指标的实现需验证以下两点：
* 使用明确定义的关联类型，表达用于标识该知识库记录其他版本的合格关联关系（例如：旧版本、新版本或替代DOI版本）；
* 该关联必须明确描述版本关联关系，不得指代其他类型的关联（例如与该记录相关的辅助文件）。

若元数据中存在至少一条明确定义的版本关联关系，则该知识库记录可通过本指标的检验。
