19202254

19202254 is an eight-digit numeric identifier used in digital cataloging and data management to uniquely tag items across systems. As a standalone number, it does not inherently convey meaning beyond its role as a unique key within a specific database or collection.

Format and interpretation vary by context. There is no universal encoding for eight-digit identifiers, so how the digits are read or segmented depends on the implementing system. Some organizations may partition the number to reflect internal subfields (for example, year, batch, or item sequence), while others treat it as an opaque surrogate key with no embedded semantics. Because of this, the same eight-digit string can represent different items in different databases.

Applications and uses. Such numbers commonly serve as primary keys, accession numbers, inventory tags, or asset identifiers across libraries, museums, archives, laboratories, and digital asset management platforms. They facilitate efficient indexing, search, and cross-referencing, especially when combined with other metadata. However, their usefulness is restricted to the system in which they are defined; they are not inherently portable or meaningful outside that context.

Relation to other identifiers. Eight-digit identifiers like 19202254 are part of broader cataloging and data-management practices that include surrogate keys and catalog numbers. They are distinct from standardized identifiers with defined schemas, such as ISBN or DOI, which carry universally recognized meanings and structures.

Creation and governance. Generation methods vary: some organizations assign sequential numbers, others derive them algorithmically or via hashing. Effective governance includes maintaining uniqueness, documenting origin and format rules, and ensuring consistent application across related datasets.
