metadata and package files

[Jonathan Koren <jo...@soe.ucsc.edu>]

I'm parsing a package file, let's say foo.tar.gz.  AutoDetectParser  
does the right thing in the sense
that returns an XHTML file that contains entries for each file in the  
tar file which is in the gzip file.  However, the metadata object   
returned by top AutoDetectParser contains only the metadata for the  
outermost package, i.e. the gzip.  Obviously the metadata for each  
file within the tar exists, otherwise PackageParser wouldn't be able  
to use AutoDetectParser to correctly chain down within the file.   
(i.e. Somewhere foo.tar/foo.pdf is tagged as application/pdf to enable  
PDFParser to correctly convert it to text.)

Examining the XHTML returned, reveals nothing.  It's just a bunch of  
<div class="package-entry">s delineating the different entries in the  
TAR.  Is there a way to get the metadata for each entry within a  
package file, and I'm just missing it?  If not, it seems like  
PackageParser could be modified to spit out a bunch of DIVs of the  
form: <div class="metadata" name="METADATA-KEY">METADATA-VALUE</div>
