  B in    two subsequent positions (e.g., subcomponents 2A and 2B will    appear when the component 2 is resolved). In the latter case, the    resolved component designation (BSDB Jxxxxxx.xx+xxxxxx.x:c2) will    be moved to the "outdated BSDB name" column, and a new    designation for the pair (BSDB Jxxxxxx.xx+xxxxxx.x:p2A-2B) will be    constructed.    

To provide BSDB numbers for all binary systems included in the BDB, we are working to appoint BSDB identifiers to binary and multiple stars of every observational type. For this purpose, we are compiling the general catalog of identifications of binaries, preliminarily named Identification List of Binaries, ILB. The ILB should include BSDB identifications for all binary systems included in the catalogs up to date, as well as leave such possibility open for the coming binary lists/catalogs/surveys.

The most representative catalogues of binary systems (from wide to close pairs) are gradually connected to the ILB. If an object is encountered for the first time, a unique BSDB identifier is attributed to it. Objects that already exist in the previously investigated catalogues are appended to the corresponding ILB entries. New objects (pairs, components) included in stellar systems already existing in ILB lead to adjustments of the relevant sections of the catalog. ILB provides cross-identification with the following widely-used and/or binary identifiers: Name/Bayer/Flamsteed, HD, HIP, GCVS, DM (BD, CD, CPD), CCDM, WDS, ADS, IDS, SBC9, IGR, PSR. Cross-ID problems are solved at this stage, and to do it properly, all available information (positional, photometric and sometimes already contained in catalogues cross-identification) is taken into account.

We believe that the principles underlaying BSDB identifier compilation do satisfy the "IAU Specifications concerning designations for astronomical radiation sources outside the solar system" (unlike, say, similarly coordinate-based WDS and CCDM names). Also, one can easily make sure that the problems typical for binary/multiple-star designation schemes are basically avoided by the BSDB.
