I'm going to define a small set of required keys for the actor dictionary, and enforce them in code.

But which keys? I feel I need a unique key representing the identity of the actor, plus a key that can be displayed in the ""You are logged in as X"" navigation. Maybe these are the same key?

So the single required key could be `id`. Problem is: is that a string or an integer? Some use-cases may call for an integer, which matches to how SQLite auto incrementing primary keys work. `admin` is a string.

Maybe `id` is required, `name` is optional - but if `name` is present then the ""You are logged in as..."" uses that in preference to `id`. `id` has to be a string, and if you want to store integer IDs in your database you need to remember to convert them to a string in your `actor_from_request` implementation.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",582526961,

`actor_from_request(datasette, request)` - returns `None` or a dictionary.

- `datasette` is a Datasette instance - useful for things like reading plugin configuration or executing queries
- `request` is a [Request object](https://datasette.readthedocs.io/en/latest/internals.html#request-object) - which means ASGI scope can be accessed as `request.scope`

A non-None value means the request is authenticated in some way. The shape of that dictionary is entirely undefined.

The second hook is for checking permissions. It can look something like this:

`permission_allowed(actor, action, resource_type, resource_identifier)`

- `actor` = the dictionary that was returned by `actor_from_scope`
- `action` = a string representing the action to be performed, e.g. `edit-schema`
- `resource_type` = a string representing the type of resource being acted on, e.g. `table`
- `resource_identifier` = a string (or maybe tuple?) representing the specific resource, e.g. the table name

I don't know if Datasette should provide default implementations of these hooks. It may be that leaving them completely up to plugins is the way to go.

I think I need to prototype this quickly to start feeling for how well it might work.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",582526961,

> * **Resources** – Which AWS resources you allow the action on. For example, what Amazon S3 buckets will you allow the user to perform the ListBucket action on? Users cannot access any resources that you do not explicitly grant permissions to.
> * **Effect** – Whether to allow or deny access. Because access is denied by default, you typically write policies where the effect is to allow.
