Labels in GraceDB

Labels are applied to events and superevents in GraceDB to indicate the state of that object. Some labels signify that an action is requested, while others signify that a follow-up process has completed and/or what the result of a follow-up process was. Here is a table showing the currently available labels and their meanings.

Protected labels

A few labels are “protected”; i.e., they are only applied by GraceDB itself as part of another process. These labels cannot be applied manually by users and any requests to do so will be rejected by the server.

At present, the following labels are protected as a part of the signoff infrastructure and are only applied by GraceDB after an operator or advocate signoff:

  • H1OK, L1OK, V1OK, ADVOK

  • H1NO, L1NO, V1NO, ADVNO
