Describe Named Tables

Description

Takes a list of named tables as the input and returns metadata for those tables from the repository. Information in the response includes the table coordinate reference system, bounding box, columns and their types, and geohash index details (scale and precision).

ACL Authorization Flow

To see the metadata of the named tables from the repository from list of named tables as input, the user (or the role they belong to) needs EXECUTE permission on the Named table.

Note: Note that the response will contain metadata for tables on which user has EXECUTE permission. If the user lists named tables for which they do not have EXECUTE permission or if they list tables that do not exist in the repository, then the metadata response for those tables will contain an access denied error.
