Overall I think it's fine. It won't continue to work as-is with the new changes to the connection to the production schema etc, so the mechanics will have to change a bit. Also need to add a link to the note book in the docs somewhere. Do we want a page in the docs for this? (or for DESC specific applications of the registry) |

Why won't the code here work as is? The connection to dataregistery happens with which ultimately makes a connection with where dr_schema is "lsst_desc_production" Yes, there should be a link to the notebook somewhere. It looks like |

There is no DEFAULT_SCHEMA_PRODUCTION anymore.
Options would be
- Import
DEFAULT_NAMESPACEand connect toschema=f"{DEFAULT_NAMESPACE}_production" - Specify or not the
DEFAULT_NAMESPACE(but no need), and choosequery_mode="production"to limit queries to production schema

| "Recall that a `DataRegistry` instance has a member `Query` which provides all the query services, the principal one being the ability to ask for values of attributes of datasets, subject to one or more filters. If you haven't already, we recommend you take a look at the tutorial \"Getting started: Part 3 - Simple queries\" before proceeding further.\n", |
