CEDAR Support for Software and Products

The CEDAR software provides many web services, and a variety of data products. This page documents our support system for CEDAR software and products.

CEDAR Support pages

We maintain support pages for CEDAR users on the CEDAR web site, including CEDAR training, a simple CEDAR orientation, and other documentation (browse around the site!). If this doesn’t meet your needs, try contacting us using the information below.


CEDAR software is hosted on GitHub under the metadatacenter project, where it can be accessed by anyone with a GitHub account. You are welcome to review the software and contact us with questions about it.

You can find a lot of detailed technical documentation about CEDAR in our GitHub documentation pages.  These describe the technical models, specifications we use like JSON-LD and RDF, our tools, and detailed programming and deployment information.

If you want to contribute to CEDAR, please let us know! The easiest way to contribute is to create a fork of the existing CEDAR repositories, then issue a pull request with your tested changes.
