2006/11/22, Tse Shing Chi (Franklin/Whale):
There is an unexpected reply located in http://www.imc.org/atom-protocol/mail-archive/msg07722.html.
Oops, sorry! (double-checked, this time, I answer to atom-syntax ;-) )
Quote: <atom:content type="image/svg+xml">...</atom:content> I don't know how to display such a content within a widget, however I know there is some program in the "registry" (Windows Registry, Freedesktop's shared MIME database, OS X configuration, etc.) which is able to open it; so I whot the summary (if any) and provide "Open with..." and "Save as..." buttons. I couldn't do that with an xhtml:object embeded in an <atom:content type="xhtml"/> (or eventually type="html"). It is almost what I want aggregators to do actually. However, web-based aggregators may have difficulties in handling it.
They could "display" the summary and provide a "Download the entry content" link. If they know how to "display" the content, then they can generate HTML code (an xhtml:object) with fallback to the summary: <object data="where/is/stored/the/entry/content" type="image/svg+xml"> <p>If you see this message, it generally means your browser does not know how to display content of type "image/svg+xml". However, the entry publisher has provided this summary for you to read:</p> <p>...entry's summary...</p> </object> <p><a href="where/is/stored/the/entry/content" hreftype="image/svg+xml">Download the entry content...</a></p>
Currently, the way to provide alternate format or text... seems to be the followings.
I personnaly have no problem with a summary acting as an alternate text (to display if the content can't be): hey, there's a valid reason why summary must be provided if the content is out-of-line or base64-encoded ;-) Alternate "formats" should be linked to using <link rel="alternate" href="..." />
Anyway, no one can ensure that aggregators will display the summary when they are [NOT] able to show the content.
Right, but I hope and expect those aggregators to either be updated or tend to disappear (because people will switch to "better" aggregators). -- Thomas Broyer
