From The MODAF System Viewpoint (SV) p44:

The SV-11 Physical Schema view defines the structure of the various kinds of system data that are utilised by the systems in the architecture.

From The MODAF System Viewpoint (SV) p44:

The SV-11 provides an implementation specific data model that realises the logical data model presented in an OV-7, Information Model.

Implementation constraints may mean that one logical entity in OV-7 is in fact realised by more than one entity in SV-11 and vice versa.

From The MODAF System Viewpoint (SV) p44:

SV-11 allows implementation-level detail of data structures to be modelled. The view serves several purposes, including:

  • Providing as much detail as possible on the system data elements exchanged between systems, thus reducing the risk of interfacing errors.
  • Providing system data structures for use in the system design process, if necessary.

SV-11 is an implementation-oriented data model that is used to describe how the information requirements represented in OV-7 are actually implemented for a given solution. The entities specified in SV-11 represent data elements (from the SV-6, Systems Data Exchange Matrix).

There should be a mapping from a given logical data model (OV-7) to the physical data model (SV- 11) if both models are used. This mapping is often not trivial (e.g. there may be conditional mappings), in which case a formal mapping language such as ISO10303-14 should be used (as M3 comments) against the data model or individual entities.

Standards associated with entities are also often identified in the development of the SV-11 view product; these should be recorded in the TV-1 Standards Profile.
