urndoi101000182

urndoi101000182 is a compound identifier that has appeared in some computer science and library science contexts as an example of cross-system identifiers. It is not defined as a standard code in major registries, and there is no widely recognized canonical meaning for this exact token. The form suggests a fusion of concepts associated with URNs and DOIs, but no official specification documents this precise string.

Structure and interpretation: The token can be read as a concatenation of three parts: "urn," "doi," and the numeric sequence "101000182." In this reading, "urn" evokes Uniform Resource Names, while "doi" points to Digital Object Identifier concepts, with the final digits representing a DOI-like suffix. However, there is no official mapping or namespace registry that links this exact token, and it is not recognized by standard URN or DOI registries.

Context and usage: In documentation and training materials, urndoi101000182 may be used as a toy example to illustrate identifier interoperability, string parsing, or data normalization workflows. It is sometimes included in datasets used to test parsing algorithms, cross-domain linking, or schema design. It should not be interpreted as representing a real object unless explicitly documented by a specific system.

Relation to related systems: The idea of combining URN and DOI aligns with broader efforts to create persistent identifiers and improve interoperability between schemas. URNs, DOIs, and other identifiers such as handles and ARKs are used to locate digital objects across systems.
