1 Scope
The present document provides the binding of the Common Service Interface information, whose semantics is defined
in ETSI EN 319 522-2 [1] and whose format is defined in ETSI EN 319 522-3 [2] to the specific services provided by
OASIS Business Metadata Service Location [3] and the OASIS Service Metadata Publishing [4]. Furthermore, the
present document specifies how to establish trust between ERDSs by use of a Trusted List [5], including the EU Trusted
List system used for qualified trust services under the Regulation (EU) No 910/2014 [i.1] using the Trusted List format
defined by the corresponding Commission implementing decision (EU) 2015/1505 [i.3], and by means of a domain
PKI.

technical specifications and formats relating to trusted lists pursuant to Article 22(5) of Regulation
(EU) No 910/2014.
3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI EN 319 522-1 [i.2] apply.
3.2 Abbreviations
For the purposes of the present document, the abbreviations given in ETSI EN 319 522-1 [i.2] apply.
4 Common Service Interface bindings - general
concepts
This part specifies the binding for the common services to specific protocols. Semantics for common services shall be
as defined in ETSI EN 319 522-2 [1] and formats shall be as defined in ETSI EN 319 522-3 [2].
Specifically:
• receiver identification service is bound to OASIS Business Document Metadata Service Location [3];
• capability discovery service is bound to OASIS Service Metadata Publisher [4];
• ERDS trust evaluation is bound to Trusted List [5] or to use of a domain PKI.
5 Capability metadata location, BDXL binding
When metadata is used, the first step is to obtain the address where the sought metadata is located. This goes for both
recipient metadata and metadata about ERDS capabilities, relevant for both the R-ERDS and intermediate ERDSs. This
clause describes use of the OASIS Business Document Metadata Service Location Version 1.0 [3] (BDXL), commonly
used with the OASIS Service Metadata Publishing (SMP) Version 1.0 [4] described in the next clause.
BDXL is based on DNS (Domain Name Service), which is a common infrastructure for the Internet. From unique
identification of an actor - the participant identifier in BDXL terms - for which metadata shall be accessed, a query
string is constructed for DNS, returning a URI to the SMP publishing metadata for the identified actor.
In the scope of the present document, the actor identified by the participant identifier is either a recipient or an ERDS,
meaning the identified SMP publishes either recipient metadata or ERDS capability metadata as defined by ETSI
EN 319 522-2 [1]. ERDS metadata is defined as an extension to SMP metadata, meaning that

This part specifies the binding for the common services to specific protocols. Semantics for common services shall be

When metadata is used, the first step is to obtain the address where the sought metadata is located. This goes for both
