Difference between Peppol and OASIS BDXR
-
OpenPeppol SMP specification
-
OASIS BDXR SMP 1.0 specification
This section lists the major differences between the OpenPeppol SMP specification and the OASIS BDXR 1.0 specification.
- Namespace URI
- Extension handling
- Data type of endpoint URI
- Changed cardinalities
Previous to the OpenPeppol SMP specification 1.2.0 the used Canonicalization algorithms was different. In the meantime the algorithm is http://www.w3.org/2006/12/xml-c14n11 for both.
The PEPPOPL SMP specification uses 2 different (self-defined) namespaces in their structures:
Additionally WS Addressing and XMLDSig namespaces need to be used.
The OASIS BDXR SMP specification uses the following namespace in their structures:
Additionally the XMLDSig namespace may be used.
The Peppol SMP specification allows for 0-1 extensions per ServiceGroup where each extension could only be an XML element.
The OASIS BDXR SMP specification allows for 0-n extensions per ServiceGroup and offers a more sophisticated data model so that extensions can be typed.
In the original Peppol SMP specification the element containing the endpoint URL is defines as follows:
{http://www.w3.org/2005/08/addressing}EndpointReference
This references a complex data type from the Web Services Addressing 1.0 specification and was technically difficult to handle.
The OASIS BDXR SMP specification changed this to a simple element called ElementURI with data type xs:anyURI.
The following cardinalities were changed:
-
Endpoint/RequireBusinessLevelSignature- Peppol: mandatory, no default value
- OASIS: optional, default value
false
-
Endpoint/@transportProfile- Peppol: optional (I think by accident)
- OASIS: mandatory

This data structure represents Metadata about a specific electronic service.
The role of the ServiceMetadata structure is to associate a participant identifier
with the ability to receive a specific document type over a specific transport. It
also describes which business processes a document can participate in, and various
operational data such as service activation and expiration times.
The ServiceMetadata resource contains all the metadata about a service that a sender

<xs:annotation>
<xs:documentation>
For recipients that want to associate more than one SMP with their participant identifier,
they may redirect senders to an alternative SMP for specific document types. To achieve
this, the ServiceMetadata element defines the optional element ‘Redirect’. This element
holds the URL of the alternative SMP, as well as the Subject Unique Identifier of the
destination SMPs certificate used to sign its resources.
In the case where a client encounters such a redirection element, the client MUST follow
the first redirect reference to the alternative SMP. If the SignedServiceMetadata resource
at the alternative SMP also contains a redirection element, the client SHOULD NOT follow
that redirect. It is the responsibility of the client to enforce this constraint.

behavior based on an extension element MUST NOT be a prerequisite for a client to
locate a service, or to make a successful request at the referenced service.

resource instances.
