Figure 2: Frame Access
The definition of interfaces and XML schemas allows the con-
nection and interaction of the pictured software components.
About 30 data interfaces support the flow of information: A
frame application accesses the DTMs through the interfaces
“IDtm“ and “IDtmInformation“ in order to manage the DTM and
inquire about the DTMs capabilities. The DTM itself accesses
the frame through another set of interfaces which allow the DTM
to acquire information from and transmit data to the frame.
Component interaction
Before going into more detail a short example about the interac-
tion of the different components mentioned so far might help to
deepen the understanding of the matter. Let us picture a FDT
based system. The run-time environment (the frame application)
was started already.
In the next step we add a CommDTM to the system topology of
the frame application. The frame is now able to inquire the
CommDTM about the supported CommChannels.
