This term has different definitions depending on the application format: A DVB-HTML locator is a link, expressed in the syntax in IETF RFC 2396 [40], which provides an unambiguous pointer to a DVB-HTML document accessible to the MHP in a specific transport stream. The schemed specified should resolve to one of the available transports signalled for the DVB-HTML application. For signed DVB-HTML applications, the schemes HTTP and HTTPS may use the return channel. This version of the specification does not include a scheme for transport independent locators; future versions are expected to do so. This term in the DVB-HTML context should not be confused with the DVB-J class of the same name.

an object used to map requests into entities

a pointer to the address of the object in the Docbase

An object in a docbase that you can use to find documents or other objects. Each locator has a Docobject Resource Locator (DRL) as one of its attributes. A DRL is the address of an object in a docbase.

The DNS/DHCP Locator object contains a reference to global defaults and DHCP options, and list of all DNS and DHCP servers, subnets, and zones in the tree.
