stamt

Stamt is a term used in speculative information-management theory to denote a compact metadata unit that attaches a data item to a stable stem and a defined time interval. The concept is fictional and used here to illustrate how temporal and hierarchical information can be organized.

A stamt comprises several fields: a globally unique identifier; a stem field that groups related items under a common conceptual category; a temporal field specifying the validity window with a start and end date; a provenance field capturing origin, transformations, and custody; and optional attributes for domain-specific metadata.

Stamts are linked into a stamt graph, with edges encoding relationships such as versioning, derivation, or lineage. This structure supports retrieval by stem and time, and preserves historical states by maintaining sequential stamts. The approach aims to separate identity, meaning, and temporal context to improve traceability.

Applications include digital archives, scientific data management, and content management systems. Proponents argue that stamts improve reproducibility and auditability by providing stable anchors for records across time. Critics note that stamts are not standardized and require governance to avoid fragmentation, inconsistencies, and interoperability challenges.

Variants include STAMT-core for core metadata and STAMT-EX for extended semantics. Lightweight implementations may use simpler schemas in constrained environments or for rapid tagging. As a theoretical construct, stamts are often used in discussions of data provenance, version control, and long-term stewardship to explore how time-anchored metadata could function in practice.
