A value of type D_Locator ist a string /N/ or X/N/ or A/ such that
§ N is a name
§ X is again a D_Locator
§ A is a positive integer used to abbreviate a Project Locator.
A Project Locator is a D_Locator
§ not starting with a number an not containing any of the names Process, Role, Aspect, Result,
– or a D_Locator of the form X/Project/N such that N is a Name and X is a D_Locator (X may start with a number).
Number 1 and 2 are reserved to abbreviate the Project Locators /Default and /WissDB.
Given a D_Locator L not starting with a number, let n(L,k) be the name on position k in this locator.
Under the assumption that n(L,k) is one of the names Project, Process, Role, Aspect, Result, and assuming further that j > 0 is the smallest number such that n(L,k+j) is again one of these names, the following restrictions apply:
§ n(L,k+1) must be different from n(L,k).
– n(L,k ) and n(L,k+j) may both be Result. In this case however we must have j > 1.
– If n(L,k) = Role, then n(L,k+j) does not exist.
– If n(L,k) = Aspect, then n(L,k+j) does not exist.
– If n(L,k ) = Project and n(L,k+j) = Process, then j = 1.
– If n(L,k ) = Process and n(L,k+j) = Role, then j = 1.
– If n(L,k ) = Process and n(L,k+j) = Aspect, then j = 1.
Given a locator L = X/Process/N or L = X/Result/N that is in use, the locator L/Description should also be in use (in other words: WissDB is to enforce that each Process or Result has a description).
Other entities may have a description but will not be forced to have one.
A general rule (WissDB will not be able to enforce) is: The locator of a knowledge item X should be prefix of the locator of another item XX if and only if
– XX is an essential part of X, or
– XX will make sense only in the context of X.
