## Example  JSON


```json
{
  "TransactionType": "DIDSet",
  "Account": "rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh",
  "Fee": "10",
  "Sequence": 391,
  "URI": "697066733A2F2F62616679626569676479727A74357366703775646D37687537367568377932366E6634646675796C71616266336F636C67747179353566627A6469",
  "Data": "",
  "SigningPubKey":"0330E7FC9D56BB25D6893BA3F317AE5BCF33B3291BD63DB32654A313222F7FD020"
}
```

##  Fields

In addition to the [common fields](/docs/references/protocol/transactions/common-fields),  transactions use the following fields:

| Field | JSON Type | [Internal Type](/docs/references/protocol/binary-format) | Required? | Description |
|  --- | --- | --- | --- | --- |
| `Data` | String | Blob | No | The public attestations of identity credentials associated with the DID. |
| `DIDDocument` | String | Blob | No | The DID document associated with the DID. |
| `URI` | String | Blob | No | The Universal Resource Identifier associated with the DID. |


You must include either `Data`, `DIDDocument`, or `URI` when you submit the `DIDSet` transaction. If all three fields are missing, the transaction fails.

To delete the `Data`, `DIDDocument`, or `URI` field from an existing DID ledger entry, add the field as an empty string.

## Error Cases

Besides errors that can occur for all transactions,  transactions can result in the following [transaction result codes](/docs/references/protocol/transactions/transaction-results):

| Error Code | Description |
|  --- | --- |
| `tecEMPTY_DID` | The transaction will create an empty DID ledger entry. Check that your updates don't remove the `Data`, `DIDDocument`, and `URI` fields. |
| `temEMPTY_DID` | The transaction is malformed and missing any DID information. Include either the `Data`, `DIDDocument`, or `URI` fields. |
