A software object may be assigned with a globally unique identifier such that it can be referenced unambiguously by humans or machines. Globally unique means an identifier should be associated with only one resource at any time. Examples of unique identifiers of data used for software include: Digital Object Identifier (DOI), the Handle System, Uniform Resource Identifier (URI) such as URL and URN, and Software Heritage Identifiers (SWHID). A data repository may assign a globally unique identifier to your data or metadata when you publish and make it available through its curation service.
