Missing link for *.ibooks in OPDS feed

[Frank Lowney]

Here is how Calibre lists an *.ibooks file in its OPDS feed:

<entry>
    <title>External Video Demo</title>
    <author>
      <name>Frank Lowney</name>
    </author>
    <id>urn:uuid:9fed4d3a-45b4-4f46-874c-bda57a052430</id>
    <updated>2014-05-10T13:11:48+00:00</updated>
    <link href="/get/cover/436" type="image/jpeg" rel="http://opds-spec.org/cover"/>
    <link href="/get/thumb/436" type="image/jpeg" rel="http://opds-spec.org/thumbnail"/>
  </entry>

Note the absence of a download link as compared with an epub in the same feed:

  <entry>
    <title>Lonely Planet's Best In Travel 2011</title>
    <author>
      <name>Lonely Planet</name>
    </author>
    <id>urn:uuid:c044ded7-5cc8-4c83-9677-865599b81d1c</id>
    <updated>2014-05-10T13:11:48+00:00</updated>
    <link href="/get/epub/434" type="application/epub+zip" rel="http://opds-spec.org/acquisition"/>
    <link href="/get/cover/434" type="image/jpeg" rel="http://opds-spec.org/cover"/>
    <link href="/get/thumb/434" type="image/jpeg" rel="http://opds-spec.org/thumbnail"/>
  </entry>

This is the missing line:

<link href="/get/epub/436" type="application/x-ibooks+zip" rel="http://opds-spec.org/acquisition"/>

... or perhaps the following would be better:

<link href="/get/ibooks/436" type="application/x-ibooks+zip" rel="http://opds-spec.org/acquisition"/>

Adding titles to these OPDS feeds would also be helpful according to the developers with whom I am working. Specifically, they say, "... suggest improvements to titles of feeds. At the feed level, all feeds are currently named « calibre Library ». More expressive names would be very useful : ex : « By Authors », « By Newest », « Author name »…"

Thanks for looking at this.

Links for the ibook format are present in feeds generated by the current
calibre release. For example:

    <link href="/get/azw3/1376" type="application/x-mobi8-ebook" rel="http://opds-spec.org/acquisition"/>
    <link href="/get/epub/1376" type="application/epub+zip" rel="http://opds-spec.org/acquisition"/>
    <link href="/get/ibook/1376" type="application/x-ibooks+zip" rel="http://opds-spec.org/acquisition"/>
    <link href="/get/cover/1376" type="image/jpeg" rel="http://opds-spec.org/cover"/>
    <link href="/get/thumb/1376" type="image/jpeg" rel="http://opds-spec.org/thumbnail"/>
