DCMTK

Currently, adding (minimal) support for a new SOP Class to the DCMTK is quite cumbersome since - depending on the type of SOP Class - changes to various files are needed (see e.g. this Howto).

In order to facilitate the work of adding new SOP Classes and of maintaining the definitions, it would be helpful to have a central place where all SOP Classes (Storage and others) are defined with their UID, Name and Features (e.g. for Storage SOP Classes, a classification like Image, SR, Waveform, etc., Patient vs. Non-Patient and so on). The current API, e.g. dcmIsaStorageSOPClassUID() or dcmIsImageStorageSOPClassUID(), should probably stay for a while. Maybe, also other UIDs such as for Transfer Syntaxes or Well-known Frame of References, should be added to this new data structure.

It would probably also be useful to think about a new naming scheme for the modality-specific (SOP class) filename prefix defined as part of the DcmModalityTable structure, since it is becoming more and more difficult to find unused but still intuitive combinations of 2 or 3 three letters.
