—？general characteristics of LDM Data Objects (LDM-DOs) that may be stored in an LDM, i.e. information on real objects such as vehicles, road works sections, slow traffic sections, special weather condition sections, etc. which are as a minimum requirement location-referenced and time-referenced;

—？service access point functions providing interfaces in an ITS station (ITS-S) to access an LDM for:

—？secure add, update and delete access for ITS-S application processes;

—？secure read access (query) for ITS-S application processes;

—？secure notifications (upon subscription) to ITS-S application processes;

—？management access:

—？secure registration, de-registration and revocation of ITS-S application processes at LDM;

—？secure subscription and cancellation of subscriptions of ITS-S application processes;

—？procedures in an LDM considering:

—？means to maintain the content and integrity of the data store;

—？mechanisms supporting several LDMs in a single ITS station unit.
