No requirements are introduced on the specific formats for the content; formats are specified in ETSI EN 319 522-3 [i.7]. Figure 1 outlines how data flows through the interfaces in the four corner model. User content shall not be changed by ERDSs. Data flowing between systems is always encrypted, as specified by the applicable binding. As detailed below, not all objects are always required. SIST EN 319 522-2 V1.1.1:2018



ETSI ETSI EN 319 522-2 V1.1.1 (2018-09) 8
Figure 1: Data flowing through interfaces For convenience, the present document defines (table 1) some aggregate constructs (ERD dispatch, ERDS receipt, ERDS serviceInfo, ERD payload, original message) which package the basic objects (user content, ERDS relay metadata, ERDS evidence, submission metadata) in different modes. Constructs define the semantic information flowing between parties, so they ease the definition of bindings [3] [4], even if, specific bindings may split the construct in its basic objects for transport. The naming convention used in the present document is that constructs whose content is completely generated by the ERDS are prefixed with "ERDS", while constructs whose content includes user generated data is prefixed with "ERD". Table 1 specifies the composition of constructs as a collection of basic objects. Table 1: Composition of constructs Basic object Construct user content ERDS relay metadata ERDS evidence submission metadata ERD message ERD dispatch 1 1 1.n 0 ERDS receipt 0 1 1.n 0 ERDS serviceInfo 0 1 0 0 ERD payload 1 1 0 0
original message 1 0 0 0.1
Table 2 provides an abstract specification of the functions provided by the ERDS APIs as defined in ETSI EN 319 522-1 [1]. SIST EN 319 522-2 V1.1.1:2018



ETSI ETSI EN 319 522-2 V1.1.1 (2018-09) 9 Table 2: Abstract interfaces Interface Provided function Description Arguments and output ERDS MSI out := SubmitMessage(og) The method is used for posting an original message to the S-ERDS. In order to use the SubmitMessage API, the UA/Application has to prove that the sender is the owner of the sender's identifier (via an authentication token, a challenge response, etc.). og: original message, composed of user content and (optional) submission metadata. out: the outcome of the method. There is no specification on the outcome, which may be a simple success/error indication, or may include a message identifier or a larger set of information. ERDS MERI out :=RetrieveMessage (mi) The method is used for retrieving a user content from the R-ERDS. Alternatively, a push of the user content to the recipient UA/application can be used through the ERD-UA MEPI interface In order to use the RetrieveMessageAPI, the UA/Application has to prove that the recipient is the owner of the recipient's identifier (via an authentication token, a challenge response, etc.). mi: this is a set of parameters which is used for the identification and retrieval of the requested user content. out: this is the outcome of the method, which, in case of success, includes the user content and possibly handover metadata and ERDS evidence. In case of failure the outcome will include error information. e := GetEvidences(ei) The method is used for retrieving one or more evidences associated to a user content which has previously been managed by the ERDS. Note that this is not the only way to obtain evidence, since an evidence can be transmitted in different ways (e.g. as an output of the SubmitMessage or the RetrieveMessage). ei: this is a set of parameters which is used for the identification and retrieval of the requested evidence.
e: the requested evidences. ERD-UA MEPI out := HandoverObjects(o) The method is used for handing over user content, ERDS evidence, handover metadata to the ERD-UA. o: a combination of user content [0.1], ERDS evidence [0.n], handover metadata [0.1], excluding void. out: this is the outcome of the method, which is a success/failure indication plus error information in case of failure.
ERDS RI out := Relay(em) The method is used for relaying an ERD message to a different ERDS. Relaying is used when S-ERDS has not the capability to deliver to the recipient itself. Metadata and evidences may be transmitted with the user content or independently from the user content through this method. em: ERD message. out: this is the outcome of the method, which is a success/failure indication plus error information in case of failure. It may also include an evidence and ERDS relay metadata. CSI re:= LookupERDS(ri) This method is used to identify the ERDS which has the capability to deliver to a defined recipient. The method may return more than one ERDS. ri: unique identification of the recipient, which may be one identifier or a set of attributes that together provides unique identification (e.g. id, domain, application protocol, etc.). re: one or more endpoints of the ERDS(s) which has(have) the capability to deliver to the recipient identified by ri. out := ValidateERDS(ei, p) This method may be used to validate the inclusion of an ERDS intro a trust circle. The method may receive some parameters for the validation (e.g. date and time of validity, specific trust circle, etc.). ei: a unique identifier for the ERDS. p: a set of parameters for the validation out: the outcome of the check, which may include a set of information about the ERDS from a trust perspective.
em := GetERDSMetadata (ei) This method is used to retrieve operational metadata about a specific ERDS.
ei: a unique identifier for the ERDS. em: a set of information about the ERDS from an operational perspective (capabilities, requirements, endpoints).

3 Definitions
For the purposes of the present document, the terms and definitions given in ETSI EN 319 522-1 [1] and the following
apply:
ERD dispatch: ERD message which contains the user content, some ERDS relay metadata and ERDS evidence
ERD payload: ERD message which contains the user content and some ERDS relay metadata
ERDS receipt: ERD message which contains ERDS evidence and some ERDS relay metadata
ERDS serviceinfo: ERD message which contains some ERDS relay metadata
4 Overview
The present document specifies the semantic content that flows across the interfaces which have been identified in ETSI
EN 319 522-1 [1]. No requirements are introduced on the specific formats for the content; formats are specified in ETSI
EN 319 522-3 [i.7].
Figure 1 outlines how data flows through the interfaces in the four corner model. User content shall not be changed by
ERDSs. Data flowing between systems is always encrypted, as specified by the applicable binding. As detailed below,
not all objects are always required.
ETSI

---------------------- Page: 7 ----------------------

Figure 1: Data flowing through interfaces
For convenience, the present document defines (table 1) some aggregate constructs (ERD dispatch, ERDS receipt,
ERDS serviceInfo, ERD payload, original message) which package the basic objects (user content, ERDS relay
metadata, ERDS evidence, submission metadata) in different modes. Constructs define the semantic information
flowing between parties, so they ease the definition of bindings [3] [4], even if, specific bindings may split the construct
in its basic objects for transport.
The naming convention used in the present document is that constructs whose content is completely generated by the
ERDS are prefixed with "ERDS", while constructs whose content includes user generated data is prefixed with "ERD".
Table 1 specifies the composition of constructs as a collection of basic objects.
Table 1: Composition of constructs
Basic object user content ERDS relay ERDS submission
Construct metadata evidence metadata
ERD dispatch 1 1 1.n 0
ERD ERDS receipt 0 1 1.n 0
message
ERDS serviceInfo 0 1 0 0
ERD payload 1 1 0 0
original message 1 0 0 0.1

Table 2 provides an abstract specification of the functions provided by the ERDS APIs as defined in ETSI
EN 319 522-1 [1].

3 Definitions
For the purposes of the present document, the terms and definitions given in ETSI EN 319 522-1 [1] and the following
apply:
ERD dispatch: ERD message which contains the user content, some ERDS relay metadata and ERDS evidence
ERD payload: ERD message which contains the user content and some ERDS relay metadata
ERDS receipt: ERD message which contains ERDS evidence and some ERDS relay metadata
ERDS serviceinfo: ERD message which contains some ERDS relay metadata
4 Overview
The present document specifies the semantic content that flows across the interfaces which have been identified in ETSI
EN 319 522-1 [1]. No requirements are introduced on the specific formats for the content; formats are specified in ETSI
EN 319 522-3 [i.7].
Figure 1 outlines how data flows through the interfaces in the four corner model. User content shall not be changed by
ERDSs. Data flowing between systems is always encrypted, as specified by the applicable binding. As detailed below,
not all objects are always required.

Figure 1: Data flowing through interfaces
For convenience, the present document defines (table 1) some aggregate constructs (ERD dispatch, ERDS receipt,
ERDS serviceInfo, ERD payload, original message) which package the basic objects (user content, ERDS relay
metadata, ERDS evidence, submission metadata) in different modes. Constructs define the semantic information
flowing between parties, so they ease the definition of bindings [3] [4], even if, specific bindings may split the construct
in its basic objects for transport.
The naming convention used in the present document is that constructs whose content is completely generated by the
ERDS are prefixed with "ERDS", while constructs whose content includes user generated data is prefixed with "ERD".
Table 1 specifies the composition of constructs as a collection of basic objects.

Table 2 provides an abstract specification of the functions provided by the ERDS APIs as defined in ETSI
EN 319 522-1 [1].
