How to Browse the Registry

CLI

List Registry Components

Assuming you have already configured dsgrid to point to the right database (URL and name), you can list components by type: projects, datasets, dimensions, dimension mappings:

$ dsgrid registry projects list
$ dsgrid registry datasets list
$ dsgrid registry dimensions list
$ dsgrid registry dimension-mappings list

You can filter the output of each table like this:

$ dsgrid registry dimensions list -f Type==geography

You can also list all components at once:

$ dsgrid registry list

You can also browse different registries by specifying the database URL and name directly on the command line:

$ dsgrid -u http://dsgrid-registry.hpc.nrel.gov:8529 -N standard-scenarios registry list

Project Viewer

dsgrid provides a Dash application that allows you to browse the registry in a web UI.

  1. Set these environment variables in preparation for starting the dsgrid API server.

$ export DSGRID_REGISTRY_DATABASE_URL=http://dsgrid-registry.hpc.nrel.gov:8529
$ export DSGRID_REGISTRY_DATABASE_NAME=standard-scenarios
$ export DSGRID_QUERY_OUTPUT_DIR=api_query_output
$ export DSGRID_API_SERVER_STORE_DIR=.

  1. Start the server

$ uvicorn dsgrid.api.app:app

Check the output for the address and port. The examples below assume that the server is running at http://127.0.0.1:8000.

  1. Start the project viewer app.

$ python dsgrid/apps/project_viewer/app.py
