A PartyRole can be contacted using a contact medium [ACIA], which is an abstraction of the commonly used contact types: email, Postal Address, telephone, fax, etc. We model a PartyRole to having contact mediums rather than a Party. This allows us to cater for role based e-mail addresses and work queues and Contact Details for a POST.<br/>An other way to contact parties is Media that is a mechanism by which processes such as “Marketing Campaign Management” and “Marketing Communications and Advertising” advertise broadly parties. It describes such mechanisms as the press, radio, trade shows, internet, and so forth.<br/>To allow for international usage, we also model the languages and dialects that Parties are able to use. Language Ability tells us which languages a party can converse in. <br/>The Language entity links to Party, not Individual, as it also allows us to represent languages that an Organization supports. For instance, a Service Provider may provide interpreters in certain languages for Customer inquiries.<br/>
