Dataset Citation and display info

[ChrisJohnNOAA]

From Bob Simons:

In datasets.xml, there could be an optional tag like
attribute1,display1,attribute2,display2
which can have 1+ pairs of values (a global attribute name and the word to display it as on web pages,
which tells ERDDAP: if attribute1 exists for a given dataset, display the display1 word and an (?) icon (which reveals the attribute value).
For Claudia, this could be
Datacite,Citation
which would tell ERDDAP: if the dataset has a "Datacite" global attribute, display it in the dataset information section on web pages as:
Citation (?)
where hovering over the (?) icon shows the Datacite value.
The good thing about this approach is that it gives the administrator full control over exactly how the citation appears. If one group likes the Datacite format, great. If another group likes some other format, that's fine for them.
I hope that make sense.
I think this is very useful to a wide variety of groups. It is very flexible. I think it is not hard to implement.

For additional context this was discussed in this thread on the users group:
