2019.1112.3015 Draft Inflection Spec: "?info"
The info inflection is a string, "?info", that may be added to an ARK before resolving it in order to request the return of human- and machine-readable metadata describing the identified object and the commitment made to it by its provider. A successful response returns metadata content as HTML intended for human consumption, along with embedded JSON -LD intended for machine consumption. Future extensions are expected that will permit the request and return of alternate formats. Embedded HTML meta tags that repeat some of the metadata using schema.org element names are recommended because not all processors recognize JSON -LD metadata. It is acceptable in the short term also to recognize the older "?" and "??" inflections and to treat them as synonymous with "?info", but their behavior may change in future versions of the ARK specification.
...
The object metadata returned in response to the info inflection depends not only on the object's immediate descriptive attributes but also on the object type and its place in a constituent cluster. For example, an ARK identifying a published article could have immediate attributes such as author (who), title (what), and date (when), but also, because it is a publication, additional core attributes such as publisher and length (number of pages). The article, one of eight in a particular issue of a journal, might also have multiple versions, in multiple formats, and might contain logical parts such as Abstract, Article, Appendices, and References. These represent its constituent cluster, which is a set of objects with which a given object has any of the following relationships: hasPart, isPartOf, isSiblingOf, HasFormat, hasVersion. For example, our article isPartOf a journal issue, hasPart References, and hasFormat(s) PDF and HTML. Because of its place in the cluster, the article's metadata should contain a link to the issue of which it is part. Note that link Link relationships within the constituent cluster exist independent of whether they are ARKs or whether they are ARKs that use the reserved '/' and '.' characters.
