Roi manager vs. labeled image (imagej2 way to handle roi's)

Hello

it’s been some time I inquired about the imagej2 way of handling regions of interest.
http://imagej.1557.x6.nabble.com/imglib2-amp-roi-handling-td5009973.html#a5010272

now I wanted ask again about the status of things:
Let’s say I got an image, segement it with any given algorithm to generate a binary mask and then want to identiry the different regions of interest (label it). With the labelled image I then want to compute measurements for the individual roi’s. Now this is well documented with the ROI manager. The problem here is that the ROI Manager and a ResultTable, that both are attached to their UI. Furthermore this extends badly to volumetrics.
What I am looking for is something to

There is the 3D suite, which does nice work using the UI

… but it seems to me this is not necessairly a good basis to develop new plugins on top of.

My principal question is how to implement a plugin using without the ROI Manager and using new data structures like Dataset that could be run headless?
Is this even possible yet? and if so, what is a good starting point?

Possible, yes. But the API is not finalized. In January 2015 the ROI API of ImgLib2 was redesigned. My understanding is that that design is not yet finished—@tpietzsch knows the details.

Regarding labelings specifically, @dietzc is the master there. Christian: is there any sample code you can point at for how things are currently being done with labelings?
