Metadata Questions and Answers

We’ve received a number of great questions and feedback from the metadata blog post last week. Since the answers to those questions are likely of interest to many people, we decided to simply post a follow-up with answers to some of the frequently asked questions.

Is Windows XP metadata compatible with Windows Vista metadata?
Look for more information on XP/Vista interop in the coming weeks and months. In the interim, a beta version of Windows Desktop Search 3.0 has been released which includes some of the APIs required for metadata support.

What other applications support XMP?
People want to know what other applications support XMP metadata. Here is a short list (all of these are available on XP today):

Why don’t my tags get written back to my photos?
If you missed it from the previous post, scroll down to the ‘your mileage may vary’ section, where we cover this topic. The most common causes are read-only files, or other permissions issues. The bottom line is – if you can’t write to the file, neither can the Photo Gallery.

    I use Flickr and have hit a brick wall as the meta-data I have entered is in the Summary fields, this adhears neither to EXIF or ITCP standards and Flickr does not recognise them, also this meta-data is easily erased as Windows is not really geared up to use or protect it.

    So I am really excited about XMP, especially as it has been given the nod from Adobe. However, what about making it easier to tag something:

    When I am logged into Vista I would like to recognise the devices that I have, and so when inserted (USB), lets say a camera, Vista recognises that camera and auto inserts my name into the images as they are uploaded from the camera.

    Would that just cut out another labourious step, auto tagging where appropriate.

    Of course issues like what name to use with tagging, may differ to the official name one gives ones own profile. Another issue would be other logins, users would have to be prompted.

    Still I would like Vista to employ this kind of canny behaviour.

  2. I’ve been reading that Vista adds it’s tagging data directly to the file (here and here). I tagged some…

    Creative Commons also recommends using XMP, see

    It would be great to see a CC plugin for Vista photo and other applications a la the Office addin recently released, see and

    I am quite excited that Windows Photo Gallery will support XMP. Still, I am wondering how will Photo Gallery resolve which metadata to use say if a caption text was added in Windows XP and a diffrent caption text was added with another application in XMP? Are hierarchical keywords supported?

    You did not answer the question about Microsoft Digital Image Suite Library. Will the meta data from that application work with the Windows Photo Gallery?

    There’s one important question for me about the metadata system:

    Does it work with RAW files? DNG would be fine, there’s no need to support every exotic camera raw file format.

    (for me and my workflow the DNG is the original picture, so attaching any property to a JPG is useless since the JPGs sometimes get reproduced from the DNG, or just deleted to free space).
