Save a paper as a JSON file.
Arguments
- paper
a paper object
- file_name
the name of the file (if NULL, defaults to the paper_id)
- save_path
the directory to save the JSON file in; there is no default, because CRAN does not allow writing into the working directory unless you ask for it
- schema_version
NULL (the default) saves the paper object as is; "12.0" saves a bibr export schema 12.0 file, for a paper read from a bibr 12.0 export or converted with
grobid_to_bibr(schema_version = "12.0"). The file keeps the paper's extraction block (a bibr export keeps bibr as its producer and the time bibr extracted it) and names metacheck as the converter.
