Users who wish to access specific software or services should click on the appropriate link to either access the software or subscribe to the services.

 

Software

Cordra® - Highly configurable open source software offered to software developers for managing digital objects with resolvable identifiers at scale. The software is available at https://cordra.org. An instance of Cordra may be accessed via the Digital Object Interface Protocol (DOIP). DOIP provides a way to interact with any type of information represented in digital form, and structured as a digital object, including the execution of any relevant operations involving that object.

DOIP-MCP Connector - The DOIP-MCP Connector enables AI and LLM client applications to access Cordra and other DOIP services. The Connector software receives MCP inputs and connects to an implementation of a DOIP service, such as that provided by a Cordra server. The Connector software is available at https://cordra.org/doip.html#doip-mcp-connector

Handle.Net® - Software for the management of persistent identifiers, including creating identifier records, updating those records, and resolving such identifiers to access their records on-line. Handle.Net software (HN_v9.3.2) is available at https://handle.net/download_hnr.html

 

Service

Handle.Net Registry - Users who are allotted a prefix from the Handle.Net Registry (HNR) will have their associated prefix handle records registered with the HNR to enable HDL.NET resolution services for their identifiers. Please click here to request CNRI to allot a prefix or renew a previously allotted prefix.

MEMS and Nanotechnology Exchange® (MNX) - The MNX provides expertise in design and fabrication services to help researchers and companies identify and develop applications using MEMS and Nanotechnology (https://mems-exchange.org).
