ROSDAL string format

ROSDAL. Linear notation scheme devised by the Beilstein Institute. It can contain just connection table information, or it may also contain atom coordinates. Several chemical information systems can convert ROSDAL strings to other structure file formats. 

The Structure Distribution File format is another means for representing inorganic compounds on a computer system. With the Gmelin Database it is used as the intrinsic storage format for substance and structure information. The SDF format has been developed to store the same amount of information as is contained in a ROSDAL string, but there is no one-to-one correspondence between different constructs of the ROSDAL specification and of the SDF format.
