Options for hierarchy

[Al Brown <albertcbrown@us.ibm.com>]

Here's the options discussed on the wg call. Currently I believe the order of preference is #4

Option 1 - children inlined inside link. Similiar to generic inline I-D proposal. Issue is which (or both) link relation to inline.
<atom:feed> (/)
<atom:entry> (/a)
<atom:id>/a;entry</atom:id>
<atom:link rel="down" type="application/atom+xml;type=feed">
<cmisra:inline>
<atom:feed>
<atom:id>/a;feed</atom:id>
<atom:entry>
<atom:id>/a/doc1</atom:id>
</atom:entry>
</atom:feed>
</cmisra:inline>

</atom:link>
<atom:link rel="down" type="application/cmistree+xml href=""/a/down"> <cmisra:inline>
<atom:feed>
<atom:id>/a;feed</atom:id>
<atom:entry>
<atom:id>/a/doc1</atom:id>
</atom:entry>
</atom:feed>
</cmisra:inline>
</link>

</atom:entry>
</atom:feed>

Option 2 - inlined, but only one link relation of a particular media type. Client code is more complex to loop through link relations.
<atom:feed> (/)
<atom:entry> (/a)
<atom:id>/a;entry</atom:id>
<atom:link rel="down" type="application/atom+xml;type=feed" />
<atom:link rel="down" type="application/cmistree+xml href=""/a/down"> <cmisra:inline>
<atom:feed>
<atom:id>/a;feed</atom:id>
<atom:entry>
<atom:id>/a/doc1</atom:id>
</atom:entry>
</atom:feed>
</cmisra:inline>
</link>

</atom:entry>
</atom:feed>

Option 3 - similiar to gd:feedLink, but only include entries, not the feed wrapper
<atom:feed> (/)
<atom:entry> (/a)
<atom:id>/a</atom:id>
<atom:link rel="down" type="application/atom+xml;type=feed" />
<atom:link rel="down" type="application/cmistree+xml href=""/a/down"></link>
<cmisra:children>
<atom:entry>
<atom:id>/a/doc1</atom:id>
</atom:entry>
</cmisra:children>

</atom:entry>
</atom:feed>

Option 4 - similiar (almost the same except cmis namespace) and include feed wrapper
<atom:feed> (/)
<atom:entry> (/a)
<atom:id>/a;entry</atom:id>
<atom:link rel="down" type="application/atom+xml;type=feed" />
<atom:link rel="down" type="application/cmistree+xml href=""/a/down">
</link>

<cmisra:children>
<atom:feed>
<atom:id>/a;feed</atom:id>
<atom:entry>
<atom:id>/a/doc1</atom:id>
</atom:entry>
</atom:feed>
</cmisra:children>
</atom:entry>
</atom:feed>
