basisitems
Basisitems is a concept used in information design and data modeling to denote the minimal, sufficient set of items from which all other items in a system can be generated or identified. The term draws an analogy to a basis in linear algebra, where a set of basis vectors spans the space; likewise, basisitems span the space of items through composition, mapping, or reference.
In practice, basisitems act as canonical building blocks. In a product catalog, basisitems might be key identifiers
Identification and properties: basisitems should be independent—no basisitem is itself derivable from the others—and spanning—every item
Applications and limitations: Basisitems support efficient metadata design, indexing, search, data integration, and deduplication. They are
Origin and related terms: The name combines basis with items, reflecting the role as foundational elements.
