Specifications and Reference Software


The Digital Object Architecture (DOA) supports information management more generally than just conveying information, in digital form, from one location to another in the Internet or other computational facilities. It is an architecture that enables interoperability across participating information systems. The DOA specifies a data model, three core components, and two protocols.

The specification of the two DOA protocols, the Digital Object Interface Protocol (DOIP) and the Digital Object Identifier and Resolution Protocol (DO-IRP) are discussed below. 


Digital Object Interface Protocol (DOIP)

The Digital Object Interface Protocol (DOIP) is a simple, but powerful conceptual protocol for software applications (“clients”) to interact with “services” which could be either the digital objects or the information systems that manage those digital objects.

If you prefer to participate in the evolution of the DOIP specification, please talk to one of your MPAs.

Version 2.0 of the DOIP Specification is available here

Digital Object Identifier Resolution Protocol (DO-IRP)

The Digital Object Identifier Resolution Protocol is a rapid-resolution protocol for creating, updating, deleting, and resolving identifiers that are globally managed and allotted. Each identifier is associated with an identifier record that clients can resolve to using this protocol. The protocol can also be used to administer the identifier records.

An earlier version of the DO-IRP was made available in a series of three RFCs (3650, 3651 and 3652) that were tied to its original implementation in the Handle System. The protocol is in the process of being updated; and the revised protocol specification will be made available shortly.


Reference Software

DOIP SDK For Java (version 2.1.0)

The Digital Object Interface Protocol (DOIP) SDK for Java is made available for developers to associate DOIP interface with various information systems. The SDK includes both server software and client software. The server software translates network requests into Java requests and Java responses into network responses. The client software provides both transport-level client library and a high-level client library that maps more directly to the conceptual usage of the protocol.

The DOIP SDK For Java (version 2.1.0) is made available to the public under this license.

Additional details are discussed in this document. The SDK itself can be directly downloaded here. Alternatively, the DOIP library from the SDK can be included in your Java application via Gradle or Maven as a dependency. Examples of how to include this library can be found below.

Digital Object Identifier Resolution Protocol (DO-IRP)

Please contact one of the credentialed MPAs to enable identifier and resolution services. A reference implementation of the DO-IRP is used for running the GHR as well as the authorized LHSs.
