The descriptor LA permits an administration privilege to be allocated for a library and the allowable storage mode to be set for its members. A library-wide borrowing mechanism can be initialized.
With WRITE-CTRL=DEACT there are no additional checks on creating or overwriting a version.
With WRITE-CTRL=ACTIV a version cannot be written unless the user ID of the person wishing to write it is recorded as the holder of the base version (which is always defined, either explicitly or implicitly) and either a new version is being created or the base version is being overwritten.
There is no base for the first version of a name; this version must be created by a user with the ADMIN privilege.
When a version is created or overwritten, a record of record type 2 is automatically created, recording the writer as HOLDER plus the DATE and TIME of the transaction. In addition the HOLD-STATE and HOLDER attributes and all privileges are applied to the new version unless the current operation calls for other values to be defined.
ACCESS-DATE=KEEP allows the date of last access to be recorded for members of the library.
