— 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.
