Description

We currently have a "parsed by" data element in the metadata, but this only works for the initial container file. It would be useful to record all parsers that touched a file and its embedded files. This information is recorded in the RecursiveParserWrapper – /rmeta, -J – but it would also be useful for the legacy e.g. /tika endpoints.

We recognize that this information will be added to the container file's metadata after the full parse and will not appear in the xhtml markup because of the way the XHTMLHandler works. However, it will appear in the json output of the /tika endpoint and for those calling Tika programmatically.
