DBA 2nd iteration Solution Architecture

Introduction

Approach: we follow the SA as was done for Intermediation (1st iteration)

Scope and focus

• Within scope
  • Modify DO/DE Mocks for S&N en Lookup patterns
  • Common component voor Cross-border subscriptions (optional for MS to use, i.e. not mandatory)
  • Event Notification + Evidence Lookup flavour, in line with PSA 2nd iteration
• Outside scope
  • Resend a subscription request in case of an error (instead the possibility to inspect the logs and manually resend a request is deemed sufficient (MVP))
  • Include the Evidence in the notification (instead pure notification + lookup)
  • Attribute Lookup

DBA OOP TS solution

Maybe this is the place to insert explanation of the subscription application collaboration (and notification?), i.e. front-end/back-end w.r.t. notifications.

The shared solution for the OOP TS consists of all common functionality of the OOP technical system. Most of the common OOP TS components need to be implemented by the data requestor and data transferor, although the OOP TS uses central components as well.

Shared solution OOP TS

Image might need an update, i.e. depict S&N and LKP shared stuff

Shared solution

The OOP TS domain (WP5) provide the data requestor and data transferor with the components needed for

1. cross-border subscription and notification messages
2. performing the lookup of an evidence

In the MVP the DBA pilot uses one type of subscription message and one type on notification message that all DC’s and DP’s involved will use. The subscription message is for subscribing to cross-border events generated at the DP. The notification message is for notifying the DC of such events. If the DC desires the Evidence can be retrieved using the Lookup. This implies an update of the IEM (WP3). There will be just one data provider per Member state: the business register, where the subscription will be recored and where the cross border events are generated, i.e.is the authentic source of company information. The DC will subscribe in one Member State at a time. The DP will notify one Member State at the time. The explicit request and the preview functions won't be needed, in both interaction patterns there is no user involvement.

Process realisation

Subscription

Based on definition on MVP some rows might disappear, i.e. for now the tables are complete w.r.t. PSA

Component description

example

Component	Short description of its use
Evidence service locator (ESL) configuration file	As the DBA pilot’s MVP uses just one type of evidence, with just one data provider per Member state (on NUTS0 level), there is no need for dynamic discovery of the data provider and its data services. For the DBA pilot it is sufficient to use a simple configuration file with the required elements (member state and participant id).
SMP	For each evidence request and response, information on the receivers Access Point (URL) and its certificates are needed. Each member state hosts an SMP for this purpose. Before sending a request or response, the sending party queries the SMP of the receiver to get this info.
DNS & SML	As there are multiple SMP’s, the sending party needs to know where to find the SMP of the receiver to get the actual metadata. This location can be found in the centrally CEF-hosted DNS, that will be queried by the access point of the sending member state. DNS entries will be created from the registration of SMP’s: the SML, which is also centrally hosted by CEF.
eDelivery AS4 gateway	This component – also referred to as eDelivery access point – handles the secure transfer of the data, including encryption and decryption as well as signing/sealing and validating signatures/seals.
DE4A Connector	The DE4A connector is the reference software that data requestors and data transferors can use to connect to the OOP TS. This eases the work by abstracting the communication with the components.

Expected logical interfaces

example

Component	Expected interface
Evidence service locator (ESL) configuration file	IN (from DE4A connector to ESL configuration file): -         Member state -         Canonical evidence type OUT from ESL configuration file to DE4A connector): -         participant ID
SMP	IN (from DE4A connector to SMP): -         Participant ID OUT (from SMP to DE4A connector): -         Service URL -         Certificate to use
DNS & SML	IN (from DE4A connector to DNS): -         Member state -         Participant ID OUT (from DNS to DE4A connector): -         SMP location
eDelivery AS4 gateway	IN (from DE4A connector to eDelivery AS4 gateway): -         evidence request OUT (from eDelivery AS4 gateway to DE4A connector): -         Evidence response
DE4A Connector	IN (from data evaluator to DE4A connector): -         Data evaluator -         Data evaluating Member state -         Requested evidence type -         Company identification (eIDASLegalPersonID, eIDASLegalName) -         Data providing Member state OUT (from DE4A connector to data evaluator): -         Data providing member state -         Data provider -         Evidence type -         Company identification (eIDASLegalPersonID, eIDASLegalName) -         Evidence (XML)

DC-specific solution

Probably makes sense to split (two images) in notification and subscription
