Creating an entry type identical to an already defined one

Question

Although there have been some posts on how to create new entry types in biblatex (1, 2, 3, 4), no post discusses how to create a new entry type that behaves exactly like one already defined.

For example, I would like to have a new entry types @talk that behaves like @inproceedings.

Why would I want this? Because I want two print two separate bibliographies in my CV. One including my talks:

\printbibliography[title=Talks, type=talk]

And another including my papers in proceedings:

\printbibliography[title=In Proceedings, type=inproceedings]

OP edit: I'm more interested in a biblatex solution, rather than in a bibtex based one. I also excluded the @event type to avoid confusions.

Answer 1

A solution for this problem is to define a filter for the bibliography using

\defbibfilter{talks}{%
  type=event or type=talk 
}

and then use

\printbibliography[title=Talks, filter=talks]
