Does Digital Edition support fallback for epub?
Hi,
I am playing around with epub format those days. I tried to embed non-standard resource files in the package and use fallback to display the alternative of those files. But seems like it didn't work. I did a litter search, and found someone had similar problem: http://www.idpf.org/forums/viewtopic...41399c30b40ec6 No body answered the post. Is there anyone knowing if the fallback is supported by current Digital Edition (1.5)? Thanks, sfan |

Very interesting question. Which kind of non-standard resources did you tried to embed in the OPF file ?
You should ask such questions to the ePub group: http://groups.yahoo.com/group/epub-community/ |

Thank you for the reply.
I just did a simple experiment with just XML files. In opf file, I defined: <item id="titlepage" href="title.xml" media-type="application/xhtml+xml"/> <item id="note" href="note.xml" media-type="application/xhtml+xml"/> <item id="kml" href="kml_sample.kml" media-type="application/google+kml" fallback="titlepage"/> In note.xml, I added a link like this: <p><a href="kml_sample.kml">KML</a></p> From my understanding, if fallback is supported, when the KML link is clicked, reader app should jump to title.xml. DE displayed KML as a link, but when I clicked, nothing happened. |

Have you tried the item with "kml" as an id in the spine first ?

<item id="kml" href="kml_sample.kml" media-type="application/google+kml" fallback="titlepage"/> Is there anything I missed? |

Hmmm, after posting my first comment, I opened up the example ePub with the test 'fallback'. At cursory glance it looks like you've done it right.
It is entirely possible that Adobe DE 1.5 does not yet support the fallback mechanism, just as it doesn't support alternative NCX navlists. |
