This metric evaluates whether there is a structured metadata representation returned upon resolution of the provided identifier.
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, when retrieved, is expressed in a structured and machine-readable format. This metric evaluates whether there is a structured metadata representation returned upon resolution of the provided identifier. The evaluation examines the returned metadata to determine whether it is expressed in a structured format. In this metric, the definition of syntactic and semantic formats follows the [FAIRsharing guidance](https://fairsharing.gitbook.io/fairsharing/about-our-records/fair-assistance/syntactic-vs-semantic-knowledge-representation-languages). Under this syntactic interpretation, a resource satisfies this metric if the resolved metadata meets these defined syntactic criteria for structured representation.
