Metadata Standard for Distributed Acoustic Sensing (DAS)

This specification defines metadata fields and JSON-based format describing Distributed Acoustic Sensing (DAS) data sets.

This specification is based on the work by the DAS Research Coordination Network (DAS-RSN) and published in Lai et al. (2024). This work is documented at: https://das-metadata.gitbook.io/das-metadata-standard-by-das-rcn

Documentation source organization

• The draft branch contains the latest draft documentation. All changes are first applied to this branch for review and merged with main for releases.
• Specification releases are tags in the form v.#.#-d#.
