Setting up a registry

[Simon O'Toole]

Hi everyone,

I have found a very simple to install system called jOAI (https://github.com/NCAR/joai-project) from the folk at the National Centre for Atmospheric Research. It’s as simple as dropping in the WAR file into a Apache Tomcat instance.

My next question is around naming authorities (viz VOResource): is it possible to become one? Who are current naming authorities? I am looking to get a valid identifier.

Thank you again!

Best wishes,
Simon
