Lineaa

Lineaa is a fictional data-structure and processing model used in theoretical discussions of sequential data handling. It is presented as a hypothetical construct to explore how linear information could be organized, transmitted, and validated in computing systems.

Origin and naming: The term combines 'line' with a stylistic suffix chosen to suggest modularity and abstraction. In worked examples, Lineaa serves as an aid for illustrating concepts such as order preservation, boundaries, and fault containment.

Core concepts: A line is the fundamental unit, consisting of content and optional metadata. A line store retains sequences of lines; a line manager enforces ordering and concurrency controls; a line router distributes lines to consumers according to a defined routing policy.

Data model and protocol: Lineaa specifies a simple, append-only model where lines may be appended with an offset and a timestamp. Operations include append, query, splice, and inspect. The model emphasizes immutability of past lines and explicit handling of boundaries.

Applications and pedagogy: Because Lineaa is hypothetical, it is used in teaching to compare streaming APIs, queueing theories, and sequential processing. It has appeared in thought experiments about distributed systems, error handling, and traceability.

Status: Lineaa has no official standard or public implementation. References are limited to educational materials and speculative discussions. The concept functions as a mental model rather than a deployed technology.
