Architect
Rational System Architect can be extended and customized in
many ways. Its drawing behavior can be customized through
a variety of selections made in the tool and the sa2001.ini file.
It's toolbars may be customized, its Matrix Editors may be
customized, its reports may be customized, and so forth.
Rational System Architect also has built-in support for
Microsoft Visual Basic for Applications, which enables the
user to write native macros that can run inside Rational
System Architect to do all sorts of things, such as adding
useful utilities, or even effecting the behavior of the tool.
Extending the In addition to all of that, one of the most powerful features of
Metamodel Rational System Architect is that users may also tailor and
through extend the underlying metamodel of how information is stored
USRPROPS.TXT in an encyclopedia. The default metamodel of a Rational
System Architect encyclopedia is specified in a file called
SAPROPS.CFG (the main System Architect properties file),
which controls things like the symbols that are on diagrams,
the relationshiip between symbols and their definitions, and
the properties of symbols, definitions, and diagrams. User
modifications to the metamodel are specified in a text file
called USRPROPS.TXT, which, when an encyclopedia is
loaded, is parsed along with SAPROPS.CFG to create a
SAPROPS.BIN file. USRPROPS.TXT overrides
SAPROPS.CFG. You may edit the USRPROPS.TXT file to
customize or extend the metamodel of an encyclopedia using
a scripting language native to Rational System Architect.

Rational System Architect‟s Encyclopedia Metamodel

Rational System
Architect’s Encyclopedia
Metamodel
What the The metamodel is a model of the way Rational System
Metamodel Architect stores the diagrams, symbols, and definitions that
Provides you create while you're doing your work. Rational System
Architect‟s metamodel includes all diagram types, symbol
types, and definition types, the properties that each of those
types contains, and various relationships between these
modeling elements.
An example of a diagram type is a Business Process
diagram; it has properties such as options whether or not to
show pools and lanes horiztonally or vertically (Vertical Pools
and Lanes), whether or not to automatically check line-symbol
connections on the diagram as you draw (Check
Connections), etc.

An example of a symbol type is a BPMN Process symbol. A
BPMN Process symbol is drawn on a Business Process
diagram – the diagram contains symbols, and symbols are
contained in a diagram – an example of two of the many
relationships in the encyclopedia metamodel. An example of a

definition type is a BPMN Process definition. A BPMN
Process symbol graphically represents a BPMN Process
definition. Most definitions are represented by a symbol; some
are not – attribute or method definition types, for example, are
not represented by any symbol on any diagram. They are both
included in (another relationship) a class definition type.
Similar to a diagram type, each definition type contains
properties. If you open a definition from Rational System
Architect‟s explorer, you will see those properties in the
definition‟s dialog, categorized into appropriate tabs and
groups.

Similar to a diagram type and a definition type, each symbol
type contains properties. If you open a symbol‟s underlying
dialog (double click on the symbol on a diagram workspace,
or right-mouse click on it and choose Edit, or select it and
choose Edit, symbol-type), you will see the properties of the
underlying definition that the symbol represents (the same as
