-#### Update Science Museum URLs
-
-One-time maintenance DAG to update Science Museum records to have valid URLs.
-See https://github.com/WordPress/openverse/issues/4261.
-
-For each Science Museum record, this DAG:
-
-- updates the url to the new format, excluding `/images/` in the path if it
-  exists
-- validates whether the url is reachable. If not, the record ID is added to an
-  `invalid_science_musem_ids` table.
-
-Once complete, we can use the `science_museum_invalid_ids` to identify records
-to delete. They are not automatically deleted by this DAG, in order to give us
-an opportunity to first see how many there are.
