Deposit form: Add further descriptions & examples to metadata fields

[max-moser]

Context & problem

We are currently user-testing our new workflow for mandatory submission reviews, but are getting some general feedback.
One very common piece of feedback is that some metadata fields are not exactly clear or even downright confusing.
Users would generally appreciate some more guidance in what is expected to be filled out in each field.

Positive examples

One field that is quite consistently mentioned as positive example is the "publication date", which has a description with listed examples:

There are a few other fields that have a short description with them, e.g.:

Desired solution

It would be good to have more metadata fields enriched with some description about when to fill it out and what is expected, especially with potentially confusing fields like:

• Dates: This field is rarely filled out and it should be made clearer that this field can be optionally used to add milestone markers or similar
• Awards/grants: This seems to be a generally very confusing field, not helped by the fact that in our instance we currently don't have any vocabulary entries for "standard" awards (this is currently WIP)
• Alternate identifiers: Typically uploads in our system don't have alternate identifiers because it's the initial publication of the dataset, so this field is somewhat unexpected for many users
• References: Not even I know what this really is
