### Execute Explain example (coming soon)

### Sharing Private Documents With Others

To share a document (or grant a more restricted access) with another actor, we must add a relationship between the
actor and the document. Inorder to make the relationship we require all of the following:

1) **Target DocID**: The `docID` of the document we want to make a relationship for.
2) **Collection Name**: The name of the collection that has the `Target DocID`.
3) **Relation Name**: The type of relation (name must be defined within the linked policy on collection).
4) **Target Identity**: The identity of the actor the relationship is being made with.
5) **Requesting Identity**: The identity of the actor that is making the request.

Note:
- ACP must be available (i.e. ACP can not be disabled).
- The collection with the target document must have a valid policy and resource linked.
- The target document must be registered with ACP already (private document).
- The requesting identity MUST either be the owner OR the manager (manages the relation) of the resource.
- If the specified relation was not granted the miminum DPI permissions (read or write) within the policy,
and a relationship is formed, the subject/actor will still not be able to access (read or write) the resource.
- If the relationship already exists, then it will just be a no-op.

Consider the following policy that we have under `examples/dpi_policy/user_dpi_policy_with_manages.yml`:

```yaml
name: An Example Policy

description: A Policy

actor:
name: actor

resources:
users:
permissions:
read:
expr: owner + reader + writer

write:
expr: owner + writer

nothing:

- actor

reader:
types:

writer:

dummy:
types:

```
Add the policy:
```sh
defradb client acp policy add -f examples/dpi_policy/user_dpi_policy_with_manages.yml \
--identity e3b722906ee4e56368f581cd8b18ab0f48af1ea53e635e3f7b8acd076676f6ac
```

Result:
```json
{
"PolicyID": "ec11b7e29a4e195f95787e2ec9b65af134718d16a2c9cd655b5e04562d1cabf9"
}
```

Add schema, linking to the users resource and our policyID:
```sh
defradb client schema add '
type Users @policy(
id: "ec11b7e29a4e195f95787e2ec9b65af134718d16a2c9cd655b5e04562d1cabf9",
resource: "users"
) {
name: String
age: Int
}
'
```

Result:
```json
[
{
"Name": "Users",
"ID": 1,
"RootID": 1,

"ResourceName": "users"
},
"IsMaterialized": true
}
]
```

Create a private document:
```sh
defradb client collection create --name Users '[{ "name": "SecretShahzadLone" }]' \
--identity e3b722906ee4e56368f581cd8b18ab0f48af1ea53e635e3f7b8acd076676f6ac
```

Only the owner can see it:
```sh
defradb client collection docIDs --identity e3b722906ee4e56368f581cd8b18ab0f48af1ea53e635e3f7b8acd076676f6ac
```

Result:
```json
{
"docID": "bae-ff3ceb1c-b5c0-5e86-a024-dd1b16a4261c",
"error": ""
}
```

Another actor can not:
```sh
defradb client collection docIDs --identity 4d092126012ebaf56161716018a71630d99443d9d5217e9d8502bb5c5456f2c5
```

**Result is empty from the above command**


Now let's make the other actor a reader of the document by adding a relationship:
```sh
defradb client acp relationship add \
--collection Users \
--docID bae-ff3ceb1c-b5c0-5e86-a024-dd1b16a4261c \
--relation reader \
--actor did:key:z7r8os2G88XXBNBTLj3kFR5rzUJ4VAesbX7PgsA68ak9B5RYcXF5EZEmjRzzinZndPSSwujXb4XKHG6vmKEFG6ZfsfcQn \
--identity e3b722906ee4e56368f581cd8b18ab0f48af1ea53e635e3f7b8acd076676f6ac
```

Result:
```json
{
"ExistedAlready": false
}
```

**Note: If the same relationship is created again the `ExistedAlready` would then be true, indicating no-op**

Now the other actor can read:
```sh
defradb client collection docIDs --identity 4d092126012ebaf56161716018a71630d99443d9d5217e9d8502bb5c5456f2c5
```

Result:
```json
{
"docID": "bae-ff3ceb1c-b5c0-5e86-a024-dd1b16a4261c",
"error": ""
}
```

But, they still can not perform an update as they were only granted a read permission (through `reader` relation):
```sh
defradb client collection update --name Users --docID "bae-ff3ceb1c-b5c0-5e86-a024-dd1b16a4261c" \
--identity 4d092126012ebaf56161716018a71630d99443d9d5217e9d8502bb5c5456f2c5 '{ "name": "SecretUpdatedShahzad" }'
```

Result:
```sh
Error: document not found or not authorized to access
```
