#' Get json Metadata and XHTML Content 
#'
#'  Tika can parse and extract text from almost anything, including zip, tar, tar.bz2, and other archives that contain documents.
#'  If you have a zip file with 100 text files in it, you can get the text and metadata for each file nested inside of the zip file.
#'  This recursive output is currently used for the jsonified mode. See:  https://wiki.apache.org/tika/RecursiveMetadata
#'  
#'  The document content is XHTML in the "X-TIKA:content" field.
#'   
#'  If \code{output_dir} is specified, files will have the \code{.json} file extension.
#'
#' @param input Character vector describing the paths and/or urls to the input documents.
#' @param ... Other parameters to be sent to \code{tika()}.
#' @return A character vector in the same order and with the same length as \code{input}, of unparsed \code{json}. Unprocessed files are \code{as.character(NA)}.
