There is was a presentation on a conference.

Because of that there is a “conference paper” published in a conference proceeding/journal: Not the slides. It is like a tiny article.

And there exists a “presentation”: A PDF file with the slides - some cracy people using PowerPoint here

How would you represent this with BibLaTeX? I like the idea to know the difference between this two types when looking at the entry-type. But currently I see no better way to use @InProceedings for both of them.

The conference paper:

```
@InProceedings{Hirt2018a,
author = {Julian Hirt and Christian Buhtz and Katrin Balzar and Gabriele Meyer},
title = {Entwicklung und Validierung eines geographischen Suchfilters für Publikationen in pflegewissenschaftlichen High Impact Journals von Pflegewissenschaftlerinnen und Pflegewissenschaftlern aus dem deutschsprachigen Raum},
year = {2018},
maintitle = {Vielfalt leben - Offenheit erhalten. Multiperspektivität und Interdisziplinarität in Pflege - Praxis - Wissenschaft},
eventtitle = {Forschungswelten 2018},
eventdate = {2018-04-19/2018-04-20},
venue = {St. Gallen, Switzerland},
}
```

The presentation/slides

```
