10. CORBA Trader - Features I

• Service publishers submit 'offers' to the Trader.

• Each offer includes the service type, a set of properties (which are service type dependent), and a handle to the object class, representing the advertised service.

• Service consumers/subscribers search for objects that match their requirements using a 'constraint language'.

  • One such language is defined as part of the Trader specification.
  • Other dedicated scripts can be also supported by dynamical binding of associated interpreters.

• The Default constraint language specifies queries in terms of the service properties, connected/related via the standard set of mathematical, boolean and set-theoretical unary or binary operators.
