Alternate IDs for judicial officers

API table: judicial_officer_aliases

The Maryland Judiciary sometimes lists more than one ID for the same judicial officer. This table records those alternate IDs.

Definitions have been recorded for some columns and not others. A column with no definition below has not been documented yet.

A field with a fixed, closed set of values lists that set below. A field with documented codes lists its known values, and shows a meaning for the ones that have been described. Other value lists are not published here. Licensed clients can read them through GET /metadata.
