- curious question from me: what is the point of putting a DOI in the
FITS file? If the DOI describes the FITS file itself and you are able to
read the REFERENC keyword I s'pect you have the actual digital object
in hand already. The real question is: what does "the DOI" actually
mean? It is totally up to the publisher to define what is meant by "a
DOI", and hence, what do you expect to see on the webpage of that DOI
once it resolves. Again this is not the responsibility of FITS but of
the publisher of the DOI, and later the "owner" or "maintainer" in case
the DOIs were transferred to a new owner/maintainer.<br>

<br>
There's several issues here that I can see:<br>
<br>
- The "only works if somebody keeps paying the rent" is only partially correct I'm afraid - I'll explain below.<br>
<br>
- someone in the DOI system dropped the ball (IOP by the looks of it). This is not a fault of the FITS system or design nor do I think FITS should try to fix that. The organization dropping the ball should be reminded of their contract they signed with their DOI consortium and make the DOIs resolve again. (see also explanation below).<br>
<br>
- any "REFERENC" value in a FITS file that points outside the FITS file itself will be liable to #FAIL and almost by definition will violate the FITS self-describing, self-containing design paradigm<br>
<br>
- curious question from me: what is the point of putting a DOI in the FITS file? If the DOI describes the FITS file itself and you are able to read the REFERENC keyword I s'pect you have the actual digital object in hand already. The real question is: what does "the DOI" actually mean? It is totally up to the publisher to define what is meant by "a DOI", and hence, what do you expect to see on the webpage of that DOI once it resolves. Again this is not the responsibility of FITS but of the publisher of the DOI, and later the "owner" or "maintainer" in case the DOIs were transferred to a new owner/maintainer.<br>
<br>
But first for the issue at hand: maintaining DOIs after they've been issued should be a fairly low-labour-intensive task, all that's needed is a bit of Python(*) web-based system that:<br>
- its URL can be written in the DOI metadata<br>
- upon opening the DOI's URL the code finds the DOI metdata and renders it on the page<br>
You only need to alter the registered URLs for the DOIs you maintain once - if you need or want to. And keep the webserver running.<br>
This is possibly part of "the rent" that Rob is talking about.<br>
<br>
The detailed explanation of "the rent" is the fee model of DOI registration organizations such as DataCite.<br>
Maintaining or issueing DOIs comes with an annual membership fee, and on top of that, for each *new* DOI(**) that is issued in a particular year you get to pay a one-time only cost. Thus, after a DOI is issued there is no "rent" for the DOIs themselves. The costs involved are for the membership, and the obligation to keep a webserver running.<br>
<br>
>From our own example: if you manage to join a DOI consortium (which we were able to) the annual membership fee is ~500€ and we run multiple websites- and services anyway.<br>
<br>
Which I hope might show that the threshold of "maintaining" might not be as high as one would think, but yes, for sure, it's not zero.<br>
<br>
Cheers,<br>
