+1. Add a component, a method, a data format and a database to this institution. The database must include the URL of the GraphQL endpoint e.g. https://www.local.solarbuildingenvelopes.com:7501/graphql/ . Copy the UUIDs of the database and of your institution and paste it into the .env file of your `database` project. In the folder of your database, run `make down && make build up`. Sign in on https://www.local.solarbuildingenvelopes.com:7501/ with your metabase account. Create an optical dataset on https://www.local.solarbuildingenvelopes.com:7501/graphql/ using the mutation `createOpticalData`. List all pending optical datasets with the query `allPendingOpticalData`. Publish your optical dataset with the mutation `publishData`. Search your database for your optical dataset e.g. with the query `allOpticalData`. Search the metabase for your optical dataset e.g. with the query `databases{edges{node{allOpticalData`.
