Discover, share, and reuse data models.
The catalog is a free and open source repository of all data models created by the ComposeDB developer community. The catalog aims to make it as easy as possible for developers to discover, share, and reuse each others models and underlying data.
- Discover high-quality models for your app
- Share and distribute your models to others
Adding models to the catalog
Models in all deployed composites are automatically available on the catalog.
How it works:
- A developer deploys a composite containing models to testnet or mainnet
- An indexer builds a catalog of all deployed models and exposes it via API
- The catalog is automatically available on various interfaces, including ComposeDB CLI
Using models from the catalog
You need a running instance of ComposeDB server and CLI to use the catalog. See set up your environment to get started.
List all models
Using ComposeDB CLI, run the following command to list all models:
composedb model:list --table
You will see a table where each model has the following metadata properties:
Name- name of the model
ID- unique identifier (streamID) of the model
Description- description of the model
Using a single model
Fetch a single model from the catalog and convert it into a composite, using its model ID:
composedb composite:from-model kjzl6hvfrbw6c7keo17n66rxyo21nqqaa9lh491jz16od43nokz7ksfcvzi6bwc --output=my-composite.json
Using multiple models
composite:from-model command depicted above for each model you want to use in your application. Remember to change the composite file name to avoid collisions. After you have multiple composite files, merge them. See Merging Composites.
To use your newly created composite in your app, you will need to deploy and compile your composite.
