I submitted a paper that only contained a title and an abstract to an international meeting, which is one of the most important conferences in my major. I will give an oral presentation in one session of the meeting. Because it is not a full paper, I want to know whether I can put it in my CV as a publication.
If it is published in the proceedings (and if it is a major conference, would suggest it is available online), you can list is as a publication, but I would be cautious to leave it at that. I would include the information that it is an abstract. If it is in a publications section, I would make sure to differentiate between peer-reviewed and not (depending on your case).
More realistically, I would see this listed under 'presentations' section, or 'talks'. Again, this depends if you have sections for both invited talks and talks given through applications.
