The properties as described by such a metadata record constitute information about how Findable, Accessible, Interoperable and Re-usable the data is -properties that became known by the acronym FAIR 12 around 2016 and are important for the application of AI/ML. Note however that again in the citation example shown above, an unstructured component is also included containing the free-text assertion that the data is held in an institutional research data repository. Formally therefore, data is only implied by this form of citation, but at least the metadata record associated with the provided DOI can be used to confirm this. At this stage it is worth noting that around half of all the citations associated with this specific article 10 are of this type, an unusually high proportion. When an assertion is made in the narrative of this article, it can now be supported with a data citation as appropriate. Such multiple and in-context data citation can be contrasted with the conventional data availability statement nowadays found in most journal articles, introduced around 2017 and which often simply points to the single and largely context-free supporting information document listed on the article landing page.
