How to "Conference Paper" and "Presentation"

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 :grinning:

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

@InProceedings{Hirt2018b,
  author     = {Julian Hirt and Christian Buhtz and Katrin Balzar and Gabriele Meyer},
  title      = {Publikationen aus der Pflegewissenschaft in Zeitschriften mit hohem Impact Factor. Entwicklung und Validierung eines geografischen Suchfilters},
  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},
}

Why not add both files to the same entry? Then you have both the slides and the conference paper at hand.

Because I want to cite them separatly. I want to have both entries in the bibliography.

Since you want to differentiate the communication type based on the entry type:

  • For the paper, I would use inproceedings (since the paper is published in the proceedings). My understanding is that you should not use proceedings: according to biblatex documentation, proceedings is for “a single-volume conference proceedings” (i.e. the whole book), while inproceedings is for “an article in a conference proceedings” (your case).
  • For the presentation, I would use conference (since the slides were shown in the conference). Note that for biblatex, conference is an alias to inproceedings).

That sounds nice to me.

Do you see another entry-typ for a poster also?

Not among the standard biblatex entry types…
You may check the biblatex manual for additional information: http://mirrors.ctan.org/macros/latex/contrib/biblatex/doc/biblatex.pdf

You still could create your own custom entry type. However, you then probably have to adapt the style.
Or you choose “unpublished”.
