In recent years, a number of data identification technologies have been developed which purport to permanently identify digital objects. this paper, nine and systems for assigning persistent identifiers are assessed their applicability Earth science (ARKs, DOIs, XRIs, Handles, LSIDs, OIDs, PURLs, URIs/URNs/URLs, UUIDs). The evaluation used four use cases that focused on the suitability each scheme provide Unique Identifiers objects, Locators serve as Citable Locators, uniquely scientific contents objects if were reformatted. Of all identifier schemes assessed, one most closely meets requirements an Identifier is UUID scheme. Any URL/URI/IRI-based could be Locators. Since there currently no strong market leaders help make choice among them, decision must based secondary criteria. While publications now allow URLs in citations, so URL/URI/IRI discussed paper potentially Locator, DOIs adopted by commercial publishers. None here even minimally address scientifically identical numerical sets under reformatting.
