To guide your addon development, you can use the reference information found in the Addon Technical Details section of the documentation. A reference guide is also available specifically for developing DSP addons.

If you create an addon that you would like to share with your fellow Aeon, Ares, or ILLiad users, please see Submitting Addons for details on how to submit the addon for Atlas review. 

Atlas and OCLC do not support default addons or user-created addons. If you need assistance with using, troubleshooting, or writing addons, please contact Atlas Systems for a custom services quote.
