What is "eppml"

EPPML (Extensible Postal Product Model and Language) is a conceptual model for the interactions between parties of a postal communication system. Examples of such parties are mailers, posts, mail aggregators, providers of postal services and equipment and recipients. They create, publish, consume and deliver postal products.

The central concept of EPPML is the postal product. EPPML defines the structure and meaning for the information that represents a postal product. The postal product definition may be viewed as an interface between posts, their customers and other parties. The formal representation of postal products allows automated systems to efficiently consume new postal products as they are introduced by postal operators.

The current implementation of EPPML is based on XML technology, but the EPPML concepts may be implemented with other technologies (e.g. relational databases, semantic web). Each postal product is fully represented by one (and only one) postal product definition file (PPDF) which is an XML document. A PPDF must be valid under the EPPML schema.
