Looks as though the main issue has been resolved now: the idea of using values from an enumeration as template parameter for a class now finally works. While the original code already was close to what it had to be, it required a little bit of internet search to connect the missing dots: instead of writing

template <typename T> class Lx

the correct code had to be

template <swir::data::StorageFormat T> class Lx

since StorageFormat was a custom defined enumeration. With this bit out of the way I now can go ahead and set up some of the subsequent code the way I originally already had been envisioning this for the Data Access Library (DAL) developed for the LOFAR radio-telescope.
