Interdisciplinary Questions

The PSA collected 23 interdisciplinary questions as basis to provide guidance to the pilots. For each of the Reference Interaction Patterns, working hypotheses were formulated for each of the interdisciplinary questions relevant for that specific pattern. This helped to contrast the pattern and make the implications of each of them comprehensible, specifically for policy stakeholders.

[ToDo: add and update the questions from D2.4]

Multi-evidence Cases

A Multi-evidence Case is an interaction between Data Consumer and Data Provider, where the Data Consumer needs to request several pieces of evidence for a single eProcedure.

There are three distinct reasons for the Multi-evidence Case to arise.

	Multiple Data Providers	Multiple Evidence Types	Multiple Evidences of the same type	Evidences for multiple subjects
Desrcription	Multiple Data Providers, either one or several evidence types for the same subject (one user = single subject)	Single Data Provider, muliple evidences of differnt type for the same subject (one user = single subject)	Single Data Provider, multiple evidence of same type for the same subject (one user = single subject)	Single Data Provider, multiple evidence of same type for different subject (one user, multiple subjects)
Example	Example from Moving Abroad Pilot: For change of adres, several evidence types are required, such as place residence, pension claims, income, which are for most MS issued by diferent Data Providers.	Example from Moving Abroad Pilot: In some MS (i.e. ES), a national data portal consolidates evidences from different Data Owners and doing so acts as a single Data Provider for several evidence types.	Example from Studying Abroad Pilot: A student who has multiple diplomas that can be sources from the same Data Provider. (This can be either the same University or a national diploma repository, holding diplomas from different education service providers).	Example from Moving Abroad Pilot: A family is moving abroad. In that case a parent might run a single eProcedure instance requiring evidence (e.g. place of residence) from all their family members (i.e. partner, kids, dependent).
General approach	Several Evidence Requests, resulting in several Evidence Responses, all holding essentially one single evidence.	The Evidence Request and Evidence Response should include multiple canonical evidence IDs and evidence definitions respectively. The request and response would consequently hold an array of evidences.

Working Hypothesis for USI	If Data Providers are not highly integrated on MS-level, then the users needs to re-authenticate on several different platforms and perform a preview, in different platforms with potentially very different look and feel.
