# How to onboard an entity?
|
|
|
|
> Refer to [this doc](./add-new-aspect.md) if you're only interested in adding a new aspect to an existing entity
|
|
|
|
Currently, DataHub only has a support for 3 [entity] types: `datasets`, `users` and `groups`.
|
|
If you want to extend DataHub with your own use cases such as `metrics`, `charts`, `dashboards` etc, you should follow the below steps in order.
|
|
|
|
## 1. Define URN
|
|
Refer to [here](../what/urn.md) for URN definition.
|
|
|
|
## 2. Model your metadata
|
|
Refer to [metadata modelling](metadata-modelling.md) section.
|
|
Make sure to do the following:
|
|
1. Define [Aspect] models.
|
|
2. Define aspect union model. Refer to [`DatasetAspect`] as an example.
|
|
3. Define [Snapshot] model. Refer to [`DatasetSnapshot`] as an example.
|
|
4. Add your newly defined snapshot to [Snapshot Union] model.
|
|
|
|
## 3. GMA search onboarding
|
|
Refer to [search onboarding](search-onboarding.md).
|
|
|
|
## 4. GMA graph onboarding
|
|
Refer to [graph onboarding](graph-onboarding.md).
|
|
|
|
## 5. Add rest.li resource endpoints
|
|
See [`CorpUsers`] for an example of top-level [resource endpoint]. Optionally add aspect-specific [sub-resource endpoint] such as [`CorpUsersEditableInfoResource`].
|
|
|
|
