<br>
I was wondering if anyone has experience/best practices to share <br>
regarding generating DOIs for datasets that are hosted on a SDI?<br>
<br>
Research resources, including data, are encouraged to adopt Digital <br>
Object Identifiers (DOI) to identify objects persistently. They allow <br>
things to be uniquely identified and accessed reliably.<br>
<br>
From what I understand, these DOIs need to be generated by one of the <br>
registration agencies under the DOI foundation (<a href="https://www.doi.org/" rel="noreferrer noreferrer" target="_blank">https://www.doi.org/</a>). <br>
Some of these agencies, like Zenodo (<a href="https://zenodo.org/" rel="noreferrer noreferrer" target="_blank">https://zenodo.org/</a>), will generate <br>
the DOIs for free, but the issue I see is that they require the data to <br>
be hosted on their repositories. I see this as a duplication of <br>
information if the data already lives on a SDI, raising a series of <br>
issues (maintaining the data in both places, duplication of storage, etc).<br>
<br>
What would be the best approach, to keep the data (and metadata) on the <br>
SDI, but still be able to reference it as a citation?<br>
<br>
In this context, would it make sense to give up on the DOI and go for a <br>
Persistent Uniform Resource Locator (PURL)?<br>
<br>
This would be an example of a Purl:<br>

<br>
Looking forwards for your thoughts on this.<br>
<br>
Thank You,<br>

All the Best,<br>
