Hi all, > I will merge the img-metadata branch to master on Thursday.
Got a bit busy in the interim, but img-metadata is now merged to imglib.git's master branch: https://github.com/imagej/imglib/commit/e4e26aa05e0f42ff1a90e8c6d67235431471de44 The commit message gives a quick gist of the changes, including future directions. Please let me know of any questions or problems with it!
