This document: describes the functionality of a "Local Dynamic Map" (LDM) in the context of the "Bounded Secured Managed Domain" (BSMD); specifies: 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.
