Q:

What type of paper is this and how should I input it into JabRef?

As a follow up to this question I am now trying to use JabRef along with @Jonas Steins python script to manage a small literature database on my local machine. I came across the following conference paper :
http://epubs.surrey.ac.uk/852068/1/098_Argyroudis.et.al._rev.pdf
I tried adding it as "Proceedings" in JabRef but the only required fields which need to be added are:

Title
Year
Bibtexkey

I find it really strange that entries which are conference proceedings do not require anything about the name of the conference, or the authors responsible for this particular article.
Am I looking at the wrong category? If so which one should I be looking at? Here are the possibilities in JabRef:

Article
InBook
Book
Booklet
InCollection
Conference
InProceedings
Proceedings
Manual
MastersThesis
PhdThesis
TechReport
Unpublished
Misc

If this is the right category, could someone please explain why the name of the conference and the authors are not required for this literature type?
Thanks

A:

This looks like a conference paper to me, so "InProceedings" is appropriate.  
The one you thought of, "Proceedings" is for the entire conference.  i.e. the book that contains every single paper from the conference, not just a single paper. That's why there is no author field, and the title field is for the name of the conference.
BTW, definition of the categories is here: https://en.wikipedia.org/wiki/BibTeX
