read/write Windows image tags (keywords)

.

How can I read/write these tags from a file on Windows?

I'm trying to acheive it in javascript and node.js but failed to find information in any language at all so I'm looking for any clues.

.

The word tags (sometimes called keywords) seem to be unfortunately chosen, as it appears to be normally describing any metadata of a file, such as EXIF. Yet in windows you can save such descriptive-tags as one of the file tags. To start with - any idea on how are they really called?

I'm aware you can modify them using various programs, eg. in Adobe Bridge they're called keywords of a file.

.

Note: I do realise it's not the best solution of storing file tags. I really just need to work with these, since the image library I'm working with is using them heavily.

@Ben Fortune: Thanks for the clue! Still, Exif-parser gives a way to read these tags, however does not allow for writing.
