There is a UCP for a vnd.sun.star.pkg URL scheme, to access content 
within a (zip, jar) package.  See the documentation of the 
css.ucb.PackageContentProvider UNO service for details.  (There is also 
a css.uri.VndSunStarPkgUrlReferenceFactory UNO service that helps create 
such vnd.sun.star.pkg URLs.)

Underlying that is UNO services like css.packages.Package and 
css.packages.zip.ZipFileAccess.
