Description of Contents

This document is the Elastos DID Resolver specification, which is published and maintained by the Elastos Foundation. It mainly explains the definition of the Elastos DID Resolver, as well as the definition of related requests and response data. In the future, we will continue to upgrade this document so that it reflects the latest state of development of the Elastos DID technology.

Abstract

This specification defines the method and interface for resolving or querying DID on the Elastos ID side chain.

Elastos uses the JSON-RPC interface to provide the DID resolve method. For more details about JSON-RPC, please see specifications on the official website.

DID Resolve

DID Resolve is the method used to resolve specific DID documents.

Resolve Request

method

The string value contains the name of the method to be invoked. For the DID Resolve request, the value is "resolvedid".

params

The object value, which is the parameter to be included in the call of resolvedid method. The parameters are defined as follows:

  • did

    DID string. Can be a complete DID string, such as did:elastos:iVPadJq56wSRDvtD5HKvCPNryHMk3qVSU4, or just a method specific string, such as: iVPadJq56wSRDvtD5HKvCPNryHMk3qVSU4.

  • all

    Whether or not all operation history of this DID are obtained. Boolean, true or false.

id

The request identifier set by the client must include a string, numerical or null value (if contained). The value usually should not be null, and the numerals should not include decimals.

Resolve Response

jsonrpc

The JSON-RPC default response property, a string value, indicates the JSON-RPC protocol version. Must be "2.0."

result

If Resolve is executed successfully, then this member is included, and the value is the result object of resolve. If an error occurs when resolve is invoked, then this member does not exist or is null. See Resolve Result Object for the definition of the DID Resolver’s resolve result object.

error

If Resolve executes normally, then this member does not exist or is null. If there is an error in the execution of Resolve, this member is included, the value is an error object. See Error Object for the definition of error objects.

id

This member is necessary. It must be identical to the value of the id member in the request object. If an error occurs at the time of ID inspection in the request object (for example resolve error/invalid request), then this value must be null.

Resolve Result Object

When the DID Resolve executes successfully, the response must contain a result member whose value is an object containing the following members:

did

The request's target DID.

status

The numerical value type status code indicates the result status of resolving target DID. This value is an integer. The value is defined as the following:

statusmeaning

0

DID document is valid. Transaction member contains an array which is the result of requesting DID transaction.

1

DID document is expired. Transaction member contains an array which is the result of requesting DID transaction.

2

DID document is deactivated. Transaction member contains an array which is the result of requesting DID transaction.

3

DID does not exist. The result object does not contain the transaction member.

When resolving a DID, regardless of the DID status, it should return this object, and should not return the error object, as long as the resolve is executed normally. Different resolve results are expressed though different status values. For example, statuses such as DID does not exists, is expired, or is deactivated, are all normal, and should return this object. It will only return the error object when the Resolver service cannot execute resolve actions, and in general is a JSON-RPC error or a Resolver error itself.

transaction

An array object, and the elements are the ID transaction and operation information of the target DID being requested. The element is an object containing the following members:

  • txid

    The string member which is the current ID transaction's transaction id.

  • timestamp

    For the transaction time, whose value must be a valid string value conforming to RFC3339 combining the date and time, and must also be normalized to UTC time, followed in "Z."

  • operation

    The object member, which is the payload of the current ID transaction, that is, the JSON object of the DID operation.

Whenall in the parameters of Resolve DID request is false, the transaction array object only contains information from the target ID's last transaction. When all is true, the transaction array object contains all transaction information of the target DID, and the array elements are stored in descending order according to ID’s transaction time, meaning that no. #0 is the newest ID transaction.

DID Query

DID Query is a method for querying DID documents on the ID side chain. The query scope is all latest DID documents in non-deactivated state, the expired documents are in the scope.

Query Request

method

The string value contains the name of the method to be invoked. For the DID query request, the value is "query".

params

The object value, which is the parameter to be included in the call of query method. The parameters are defined as follows:

  • service

    Optional, a string representing the service type. For service type, see the definition of service in the Elastos DID method specification. Only supports single values. For complex queries, use "query".

  • credential

    Optional, a string representing the credential type. For credential type, see the definition of credential in the Elastos Verifiable Claims Specification. Only supports single values. For complex queries, use "query".

  • query

    Optional, query conditions in MongoDB query syntax, only supports the conditional syntax of MongoDB's find method.

  • skip

    Optional, the number of documents to skip in the results set. The default value is 0.

  • limit

    Optional, the number of documents returned in the result set.

    If no limit is specified, the size of the results returned is determined by the server. If the result set is large, the server may return a subset of the results to avoid excessive server resource consumption.

Although all the above three parameters service, credential and query are optional, they can only support one and must have one.

The skip and limit parameters are used to provide pagination support, which controls the subset of the query results that should be returned.

id

The request identifier set by the client must include a string, numerical or null value (if contained). The value usually should not be null, and the numerals should not include decimals.

Query Response

jsonrpc

The JSON-RPC default response property, a string value, indicates the JSON-RPC protocol version. Must be "2.0."

result

If query is executed successfully, then this member is included, and the value is the result object of query. If an error occurs when query is invoked, then this member does not exist or is null. See Query Result Object for the definition of the DID query result object.

error

If query executes normally, then this member does not exist or is null. If there is an error in the execution of query, this member is included, the value is an error object. See Error Object for the definition of error objects.

id

This member is necessary. It must be identical to the value of the id member in the request object. If an error occurs at the time of ID inspection in the request object (for example query error/invalid request), then this value must be null.

Query Result Object

When the DID Query executes successfully, the response must contain a result member whose value is an object containing the following members:

total

The total number of document that meet the query conditions.

start

The start document position of the current results set.

count

The number of documents returned in the current result set.

document

An array object, and the elements are the DID document that meet the query conditions. If there are no matching DIDs, an empty array is returned.

Examples

Querying DIDs containing specific service, return the 3rd page, 10 documents per page
