<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch adds a file metadata extractor for archive files. This extractor handles any file that can be read using KArchive.
The metadata extracted are the uncompressed size of the whole archive (shown in Dolphin, but not formatted like a file size using KB or MB suffixes), and the list of files it contains. The extractor creates one Nepomuk resource per file or directory in the archive (root directory included). These resources have the types ArchiveEntry, and FileDataObject (for files) or Folder (for directories). They also have their nie:url property set to an URL that can be used with the Archive KIO (for instance, "zip:/home/me/archive.zip/one/file" or "tar:/usr/src/linux-3.7.2.tar.xz"). For files, their fileSize is set to the uncompressed size of the file.
The files themselves are not read nor uncompressed. I haven't found a way to recursively extract metadata of archived files (for instance, launching the PlainTextExtractor on any plain text file found in the archive).</pre>

Nepomukshow displays meaningful information about the files indexed, the archive itself and the files contained in it. For a test archive, nepomukshow displays these informations :
$ nepomukshow test.zip
<nepomuk:/res/e5eddbdb-995b-472f-9ef1-3a4ba4c9999d> # Note this ID

Displaying the metadata of a file contained in the archive can be done by passing an URL to nepomukshow :
$ nepomukshow 'zip:/home/steckdenis/test.zip/'
<nepomuk:/res/71458f55-898c-4374-ad00-6ac5b1d9c9e7> # Note this ID, it is the one of the root compressed directory

When entering "6 My account1.png" in KRunner, the file is shown as an "Archive entry". When clicking on it, Gwenview is launched and displays the image.</pre>
