IDML is the new INX

InDesign has always had the ability to export a file that can be opened in a version of InDesign one version back. In the past, this was achieved by choosing File > Export and choosing the "InDesign Interchange (INX)" format. The resulting INX file can then be opened by the next-oldest version of InDesign.

Starting with InDesign CS5, the INX format is gone, replaced by the "InDesign Markup (IDML) format. This format functions exactly like the previous INX format for opening in the previous version of InDesign.

The IDML format is also useful for resurrecting a damaged InDesign file, as I wrote about previously.

Why the change? The IDML format is a well-documented XML-based format that makes it possible for developers and scripters to automate InDesign document creation and modification, beyond what was possible with the old INX format.

Plus it means that all those people using CS3 will have to upgrade if they work with designers using CS5, so Adobe wins all round.

Keith and Julie, is this true that there is no workaround between CS3 and CS5? Presumably you can back trace from CS5 to CS4 to CS3 but really nothing if you don't have access to CS4?

@Anne: Short of some sort of hack such as the one described at http://indesignsecrets.com/double-downsave.php there is no way to save directly from CS5 to CS3.

Hello Keith,

I'm having a big trouble here, cause I designed a whole magazine with CS5 and the editor has only CS4. I am sending them right now the IDML files I've exported - but to make sure he will be able to open them I'd like to send them a plugin download link that would assure that. Question is, where can I find it? I simply did not find it anywhere! Do you have any clue? Thanks a lot and congratulations on your blog, it really helped me out!

@Sergio: I don't understand what kind of "plug-in" or link that you're looking for. Can you explain further?
