**Repo protocol** is semantics and operating process for persistent storage node in NDN. The operation of NDN repo includes reading from, insertion to and deleting from data objects in NDN repository nodes.

**Repo protocol** is based on [Command Interests](http://redmine.named-data.net/projects/nfd/wiki/Command_Interests) specification.

* [NFD Control Command specification](http://redmine.named-data.net/projects/nfd/wiki/ControlCommand): The reponse of insertion and deletion command will follow the response format of this specification, but with different defination of status code.

## repo-ng

**repo-ng** (repo-new generation) is an implementation of NDN persistent in-network storage conforming to **Repo protocol**. It uses [ndn-cpp-dev](http://redmine.named-data.net/projects/ndn-cpp-dev) as NDN client library and database sqlite3 as underlying data storage.

Most parts of the protocol are supported in repo-ng. The following specifications are not supported in current version.

    36
    
    
    
* For deletion command, if EndBlockId is null in RepoCommandParameter, repo cannot response all the segmented data from StartBlockId





    37
    
    
    
* Command for checking deletion progress





    38
    
    
    





    39
    
    
    
Trust model of command validation and access control have not been designed. All the commands are validated in current version and all the commands could pass.
