I'm prototyping some BDX and other technologies and ran into the following issue:
In SML, one URI pattern is defined, to be used when a retrieving metadata for a specific document type:
http://<hash over recipientID>.<schemeID>.<SML domain>/<recipientID>/services/<documentType>
Section 2.2 of the PEPPOL SMP suggests SML/SMP also provide an interface to retrieve a ServiceGroup for a given Participant Identifier. I
n this case we don't know the document type.
What is the URI pattern to use to retrieve a ServiceGroup and where in SML or in SMP is it defined ?
When using NAPTR U
records, the second occurrence of
recipientID
in the URI would no longer needed as the record can directly reference a recipient-specific resource on the metadata server, it is not just a domain. That is an improvement.
But that raises the question how to combine that referenced resource identifier with a variable documentType. Can the regular _expression_ be used?
The
/services/
substring in the URI seems to be unnecessary in SML already.
