Blank space after meta data attribute '@type' of affiliation

[elinalutz]

When adding the meta data field 'affiliation' for a creator, the codebook contains a blank space after the affiliation type (e.g., 'Organization' as in https://rubenarslan.github.io/codebook/articles/codebook.html) and before the comma that separates the affiliation type from the affiliation name. Can this blank space be removed somehow?

This is the relevant bit of code from the codebook example with formr.org data:

metadata(bfi)$creator <- list(
      "@type" = "Person",
      givenName = "Ruben", familyName = "Arslan",
      email = "[email protected]", 
      affiliation = list("@type" = "Organization",
        name = "MPI Human Development, Berlin"))

Thank you!
