InCollection CITATION entry not mapped

[dpprdan]

InCollection CITATION entry is not mapped to a schema.org @type.

cit <- citation("knitr")
toBibtex(cit[[3]])
#> @InCollection{,
#>   booktitle = {Implementing Reproducible Computational Research},
#>   editor = {Victoria Stodden and Friedrich Leisch and Roger D. Peng},
#>   title = {knitr: A Comprehensive Tool for Reproducible Research in {R}},
#>   author = {Yihui Xie},
#>   publisher = {Chapman and Hall/CRC},
#>   year = {2014},
#>   note = {ISBN 978-1466561595},
#>   url = {http://www.crcpress.com/product/isbn/9781466561595},
#> }
knitr_path <- find.package("knitr")
cm_cit <- codemeta:::guess_citation(knitr_path) # PR #4 needed
cm_cit[[3]][["@type"]]
#> NULL

This is probably just a matching error, “InCollection” vs. “Incollection”. Better to match on lowercase, I suppose?
I can open a PR with a fix.

Relatedly, could/should booktitle, editor (and isbn), i.e. info about
the book that contains the chapter, be included via
[isPartOf](https://schema.org/isPartOf)?

Good catch. Looks like a bunch of the switch terms have all be arbitrarily capitalized, maybe they should all be lower-cased.

And yup, I think isPartOf is the way to go here.

A PR for this would be excellent!
