Service Metadata Locator (SML) software

Latest version 

Service Metadata Locator v4.0.0


About the software component

The CEF eDelivery Service Metadata Locator (SML) enables Access Points to dynamically discover the IP address of the destination Access Point. Instead of looking at a static list of IP addresses, the Access Point consults a Service Metadata Publisher (SMP) where information about every participant in the document/ data exchange network is kept up to date, including the IP addresses of their Access Point. As at any point in time there can be one or several active SMPs in a same network. For dynamic discovery to work, every participant must be given a unique ID in the form of a website's URL which must be known on the internet's Domain Name System (DNS) thanks to the Service Metadata Locator (SML). By knowing this URL, the Access Point is able to dynamically locate the right SMP and therefore the right Access Point.

The current SML software component maintained by the European Commission implements the OASIS Business Document Metadata Service Location (BDXL) specification. Conformance with the PEPPOL Transport Infrastructure SML specifications will be maintained according to the the PEPPOL Transport Infrastructure SML specifications.


The software component is available now.
The component description is coming soon.
