Making CS4 File Info Panels Work In CS5
May 19, 2010Unfortunately your CS4 Panels will not just drop in and work with CS5.
If you created a custom panel with Flex/Flash Builder, you will need to rebuild the panel with the new CS5 XMP FileInfo SDK 5.1 libraries.
If you used the Generic Panel and modified the properties.xml file, then you will need to use the new CS5 Generic Panel. Most likely you can reuse the same properties.xml file – see caveat below…
From the Readme of the CS5 XMP File Info SDK
1) Custom Panels that have been built with the CS4 SDK
have to be rebuild with this CS5 SDK to work within CS5.
2) The Generic Panel’s schema files are fully compatible,
but the Generic Panel included with CS5 SDK has to be used.
3) Panels built with the CS5 SDK will also work in CS4
as long as the XMPDataGrid component is not used.
If you are using Custom CS3 File Info panels, then you need to rebuild them completely using the Generic Panel or with Flex/Flash Builder.
From Gunar 
With yesterdays XMP FileInfo 3.1 update, distributed via the Adobe Application Manager, the compatibility issue is fixed. Now, CS4 custom panels are also working in CS5 without being recompiled.

A general question…
CS5 just came out…but one day CS6 and CS7…what are the fundamentals of updating a custom panel regardless of software version.
Would it be correct to say that…as long as the namespace or namespace prefix and property names are the same when rebuilding in the new version, that any software that ingests the metadata should have little problems?
I’m starting to get a nice set of custom panels in CS5 but of course would like to know what one might be up against in the future when everyone starts to use CS6 or beyond.
