NonURLbased

NonURLbased is a term used to describe digital identifiers or references that do not rely on the Uniform Resource Locator (URL) protocol for their structure or resolution. URLs, which typically begin with "http://" or "https://", are designed to locate resources on the internet. In contrast, nonURLbased identifiers use alternative methods to represent and access information.

These identifiers can take many forms and serve various purposes. Examples include Digital Object Identifiers (DOIs), which are persistent identifiers for scholarly articles and other academic resources, and handles, a more general framework for persistent identification of digital objects. Other nonURLbased systems might employ proprietary schemes or use formats like Universal Product Codes (UPCs) for physical goods, or International Standard Book Numbers (ISBNs) for books.

The motivation behind using nonURLbased identifiers often stems from a need for greater stability and persistence. URLs can change if the location or name of a resource is altered, making them prone to becoming broken links. NonURLbased systems are typically designed so that the identifier itself remains constant, even if the underlying resource moves or is updated. This is crucial for long-term archiving, citation, and reliable retrieval of information. The resolution of these identifiers is managed by dedicated services, ensuring that the correct resource is found regardless of its current location.
