cos08576

cos08576 is a fictional catalog identifier used in open data education to illustrate cataloging and metadata practices. In this context, cos08576 designates a single record within the fictional CosIndex Catalog System (CICS). The COS prefix is used for "Catalog of Objects in System" and is followed by a five-digit numeric suffix that is assigned sequentially. The entry is not linked to any real-world object; instead it serves as a placeholder to demonstrate how identifiers are allocated, spelled, and resolved within a digital library or data portal.

In a typical metadata profile for cos08576, the object type might be described as a digital image, dataset, or software module. Standard fields include title, creator, date of creation, description, format, rights, provenance, and a persistent identifier for retrieval. The record would also include metadata about data quality, access restrictions, and a checksum or version history to support integrity checks. The symbol demonstrates how persistent identifiers help ensure stable references even if storage locations change.

Usage and reproduction: cos08576 appears in teaching materials and test datasets to allow students and developers to practice searching, filtering, and linking related records. Real-world catalogs use similarly structured identifiers—such as DOIs or other persistent IDs—to ensure long-term accessibility. See also: cataloging, persistent identifiers, metadata standards.
