One of the most relevant features of the CiaoPP system is that it allows the addition of new analysis domains to the abstract interpretation-based framework in an easy way.
The next Chapter (Plug-in points for abstract domains) describes the module domains.pl, the general interface used by the analyzer for accessing the operations of the different domains implemented in the system. The developer of a new domain must edit this module, adding the necessary clauses to link the general interface with the specific operations of the new domain.
The procedure of adding a new domain is illustrated in Simple groundness abstract domain by means of a simple abstract domain for groundness information inference. It includes a list of the predicates that need to be implemented by the developer in order to add the abstract domain to CiaoPP.
