What are metadata fields?

Metadata fields allow the association of data values to robologs, enriching robologs to improve searchability and analysis of robolog data.

Classification of metadata fields

Intrinsic metadata​

Intrinsic metadata field values are written to a robolog (e.g., Start Time and Duration) or are associated with the robolog during ingestion into the Model-Prime platform (e.g., Robolog ID, Ingested At, and Robolog URI). Intrinsic values written to the robolog are typically extracted by running rosbag info in ROS 1 or stored in the metadata.yaml file in ROS 2.

Important: Intrinsic metadata attributes are not mutable.

Extrinsic metadata​

Extrinsic metatdata field values are attributes written by organizational processes to further enrich the robolog data. Examples of these processes include:

  • Manual triaging of logs by an analyst, who may want to add an annotation about their observation,
  • Uploading of supplementary files containing metadata related to a robolog, and
  • Tagging of logs by an operational engineer.
