Lähdeviesti

Lähdeviesti is a Finnish term literally meaning "source message" or "originating message." It is a compound of lähde (source) and viesti (message) and is used in various contexts to refer to the original information from which other data, messages, or interpretations are derived. The term is primarily encountered in Finnish-language discussions of information flow, data processing, and communication.

In information technology and data processing, lähdeviesti can denote the original input or payload that is transformed, filtered, or routed to produce subsequent messages, logs, or outputs. It is used to emphasize provenance, traceability, and the ability to reconstruct processing steps from the source data. In this context, it often appears alongside related concepts such as target messages, transformed outputs, or processing pipelines.

In journalism and media, lähdeviesti may be used to describe the initial information, document, or piece of evidence that a report or article builds upon. Here the term highlights the importance of origin and reliability of information, as well as the relationship between the source material and the published story.

The term is general and informal in usage; it does not denote a single standardized concept across all industries. Depending on the field, it may be used more specifically to indicate provenance, authenticity, or the lineage of a message from its origin to its downstream representations.
