JPEGS exported from ViewNX 2 have 'Uncalibrated' as color space. Is this right?

I have a similar problem in that when I convert files using NX the saved file - be it tiff or jpeg doesnt display the shooting info in file properties as it does if I save it through my photo editing prog (corel x5).
If someone else can shed some light on this we would appreciate it.

Edit:
After looking again at the Windows 8 right click window for the exported images, i made a mistake as it says Color Representation NOT Color Space - I'm not sure what the difference is. Surely it should still say sRGB though as the NEF's i'm working with are shot in sRGB.

Jpeg is a compressed format made small for faster transmission through web sites, and computer storage. It was defined when transmission speeds were slower, and storage systems were more expensive. By its very nature, to achieve that compression, data is discarded... To make things even more confusing (and the format less robust) there are several definitions/levels of compression... The more you compress, the more data gets discarded...
It seems only logical, that the first things you start dumping when compressing graphic files, is data that's not related to the screen image itself...
You can see that here in how this forum's software strips out the EXIF data in the interests of file storage space reduction...
It's of interest to us here because we naturally want to see that data as part of a learning process with photography... On the other hand, it never becomes a topic of discussion on other sites because the images aren't integral to the discussion other than as the message the image conveys...

First, let me preface everything with, I quit using the NX product after the first 30 minutes of loading it... Having spent the last 40+ years in software development and design... it's considered very basic manufacturer's software... Something Nikon produces ONLY because they have to produce something...
There's no telling, given the options available, as to what data Nikon determines is irrelevant, and discards when compressing their NEF data to a Jpeg format... IOW, I'm not surprised to hear that the color space data is omitted, and I'm not surprised to hear that they may also have a different definition called Color Representation...

This should help...
The Solution to Nikon software incorrectly tagging the EXIF Colorspace Tag is as follows:
When saving as a .JPG or .TIF format, a Save Options Dialog box will appear such as this one for .JPG:
Or this one for .TIF:
Simply uncheck the option to Embed ICC profile. The profile will still be used, and the EXIF Colorspace tag will now be correctly written so that other applications and scripts can read the data.
The method that Nikon/Nik Software uses to embed the ICC Profile within the EXIF data structure, prevents applications and scripts from reading the data.

Hi Whitelight, thanks for the reply.
The advice you stated says to uncheck the option to Embed ICC profile. Does the image file not need the ICC profile embedded?
