[Openicc] Fwd: Settings bundles (Robert Krawitz, Edmund Ronald)

[Chris Murphy]

For what it's worth, I am increasingly not a huge XML fan due in no small part to CxF. It is a nightmare to sort out visually. It's like reading code that pretends to be plain English readable. It's far worse than a CGATS file to a mortal. I understand the need for extended beyond basic CGATS files, but CxF is user hostile to look at inside. 

I'm seeing files that repeat the date of each measurement 10000 times. There are 5000 patches represented in the data set, which have 5000 reference device values, each with date/time stamp, and 5000 measurement values, each with a time stamp. The word cyan is repeated 10000 times instead of once in a single column. The word tag is repeated 25000 times. It such a complete mess to sift through. I guess fully 90% of the content of the file is repetitive, extraneously, useless garbage, visually speaking.

And the measurement data is not co-located with the device data. The top 1/2 of the CxF contains LAB values, the bottom 1/2 the device values. On and on. It's just nasty. It is definitely not easier than a CGATS file if you want something human readable. These particular XML files are only slightly more transparent than a binary ICC file.

So if the idea is for these files to be readable by users of any sort (non-programmers) then I'd reject XML. If the idea is for the files to be more easily parsed by programmers for troubleshooting and engineering purposes, then the format doesn't matter to me much, and XML is fine.
