DomiSML (Domain Interoperability Service Metadata Locator) is a sample implementation provided by the European Commission as part of the eDelivery Building Block. It is responsible for dynamic service location, allowing a sender to discover where a receiver's information is stored. DomiSML adds, updates and deletes information about participants' Service Metadata Publisher (SMP) locations on the DNS, guiding senders to the appropriate SMP. It is based on the eDelivery BDXL profile and the PEPPOL SML Specification.
