Overview
The International Federation of Digital Seismograph Networks (FDSN) defines DAS Metadata as a metadata format for describing Distributed Acoustic Sensing (DAS) data sets.
The goals of this format are to provide an open standard for the description of DAS data sets to allow compare and integrate measurements across deployments, to make the data reusable by others following Findable, Accessible, Interoperable, and Reusable (FAIR) data principles, to facilitate the exchange of metadata between users and data centers, and to provide a mechanism for data centers to validate the correctness of metadata. The format is designed to be flexible and extensible to accommodate the wide variety of data sets that are collected by different organizations.
This standard fully describes the five key components of a DAS experiment: interrogator, data acquisition, channels, cable, and fiber. The intent is that this metadata standard should be independent of the specific implementation and the emphasis is on the content and structure (i.e., schema). This also implies that the metadata is independent of the time-series data.
Getting started
Read the Terms and Definitions to understand the key concepts and terminology used in the schema.
Read about the Structure to understand the organization of the schema.
Review the Example Scenarios to see how the schema can be used to describe different DAS deployments.
Review the Metadata Examples to see how the schema can be used to describe specific DAS deployments.
