----------------------------------------

             Summary: Embedded documents in RTF are not extracted
                 Key: TIKA-1010
                 URL: https://issues.apache.org/jira/browse/TIKA-1010
             Project: Tika
          Issue Type: Bug
          Components: parser
            Reporter: Michael McCandless


When an RTF doc embeds a doc it looks like this:

{noformat}
{\object\objemb
\objw628\objh765{\*\objclass Package}{\*\objdata 0105000002000000080000005061636b61676500000000000000000066000000

{noformat}

But, unfortunately, the format of those hex bytes is not spelled out
in the RTF spec ... the spec merely says the bytes are saved by the
OLESaveToStream function ... and I haven't been able to find a
description of what the bytes mean.

In this case they are a "Package object" (\objclass Package), which I
think is an [old?] way to wrap any non-OLE file (this is just a .txt
file).

Here's the hex dump:

{noformat}

Anyway I have no idea how to decode the bytes at this point ... just
opening the issue in case anyone else does!
