= RDS/WIP Identifier Generator =

There has long been a need for an identifier generator in this project, and so we now have an [http://rdswip.ids-adi.org/servlets/registry?registry-op=ui experimental one].

= Features =

 * Allocates identifiers in a given name space (you supply the base URI).
 * All identifiers are stored in their name space in a single triplestore.
 * All identifiers have the form RNNNNNN where NNNNNN are digits and R is literal.
 * NNNNNN will never start with a zero.
 * NNNNNN will never contain a sequence NNN of three of the same digits.
 * NNNNNN will never contain any digit more than three times.
 * Results in 862407 possible identifiers from R100000 to R999999.
 * NNNNNN is allocated with a strong random number generator (PRNG seeded from an RNG).
 * There is intentionally no support for allocating "sequences" of identifiers.
 * There is intentionally no support for allocating "bulk" identifiers.

= Principles =

 * No one can choose their identifier.
 * No one can inadvertently create implicit knowledge by "owning" a block of identifiers - knowledge should be explicit, reservation blocks denied.
 * No one can create "de facto" maps by allocating sequences that relate to other existing identifiers (again, to avoid creating implicit knowledge).
 * Identifiers are of the same length (at least until "slots" become too sparse to find quickly, which will likely happen when its about 80% full).

= Governance =

 * Any abuse of the system (ie. trying to circumvent the principles) should result in suspension of the service for the offending user and revocation of the abusing allocations.

= Agenda =

 * Need to apply authentication/authorization (very quick to do).
 * Need to decide on a registry namespace & properties.
 * Need to decide if we record the allocater's user id and date.
