DEFINE_STANDARD_HANDLE(Interface_InterfaceModel, Standard_Transient)

//! Defines an (Indexed) Set of data corresponding to a complete
//! Transfer by a File Interface, i.e. File Header and Transient
//! Entities (Objects) contained in a File. Contained Entities are
//! identified in the Model by unique and consecutive Numbers.
//!
//! In addition, a Model can attach to each entity, a specific
//! Label according to the norm (e.g. Name for VDA, #ident for
//! Step ...), intended to be output on a string or a stream
//! (remark : labels are not obliged to be unique)
//!
//! InterfaceModel itself is not Transient, it is intended to
//! work on a set of Transient Data. The services offered are
//! basic Listing and Identification operations on Transient
//! Entities, storage of Error Reports, Copying.
//!
//! Moreovere, it is possible to define and use templates. These
//! are empty Models, from which copies can be obtained in order
//! to be filled with effective data. This allows to record
//! standard definitions for headers, avoiding to recreate them
//! for each sendings, and assuring customisation of produced
//! files for a given site.
//! A template is attached to a name. It is possible to define a
//! template from another one (get it, edit it then record it
//! under another name).
//!
//! See also Graph, ShareTool, CheckTool for more
