The PEPPOL Central Registry

In order to deliver electronic documents from a sender to the correct recipient, all PEPPOL Access Points need to know about each other and the participants they support.

To do this PEPPOL maintains one centralized service, called the Service Metadata Locator (SML). The PEPPOL SML defines which Service Metadata Publisher (SMP) to use for finding out the delivery details of any PEPPOL participant. This is a similar approach to how the World Wide Web is able to find websites based on their domain names.

The PEPPOL SML is a core service that identifies all PEPPOL trusted Access Points and SMPs.
