In spite of the big number in already deposited substances, it seems of course over and over again that one would like to go after certain materials by hand. This should be permitted of course only to well-chosen and accordingly certified employees. On account of the individual user's rights within the system, this is to be guaranteed.
With the new capture of a substance all qualities about the material data bank can be built in. In particular CAS number, synonymous danger class and physical qualities (density, boiling point, etc.). Should the data not be given at the present time yet or only incompletely, one can complement this of course later at every time.
Besides it is possible to define new qualities and to assign to the single substances. Therefore the SciDex-based data bank system is to be extended and to adapt by CLAKS almost arbitrarily.
