Delta velocity: In addition to the linear acceleration measurements along each axis (x, y, and z), the ADIS16505 also provides delta velocity measurements that represent a calculation of linear velocity change between each sample update. Seeing how we cannot find something more suitable, do you think it would make sense to add these new channels to IIO: something like IIO_DELTA_VELOCITY and IIO_DELTA_ANGLE and specify in ABI docs that these measurements are relative to the previous sample? Or do you have something else in mind?
