Cable metadata

Cable Metadata

• The Cable metadata is designed to allow investigators to describe the cable used in their experiment, which could be one continuous long cable, or cables with multiple connectors or across several installation environments. There are also parameters relating to the general geographical location of the cable to facilitate searchability in future databases. The Cable metadata should include available information on the cable and its installation as this knowledge may help in developing a system-level description of the exact cable response.

• Required fields (mark with an asterisk, and indicated in the tables below) cable_id* | cable_bounding_box*

• Optional fields cable_owner | cable_installation_date | cable_removal_date | cable_characteristics | cable_environment | cable_installation_environment | cable_model | cable_outside_diameter | cable_outside_diameter_unit | comment
