Underlying assumptions

• DI technology could in principle be deployed vertically integrated on a per ecosystem basis - but we are not interested in this approach
• We are only interested in deploying DI technology with a strong horizontal integration to achieve interoperation with other ecosystems
• We assume that the EU efforts around eIDASv2/EBSI/EUDI Wallet and such will be a focal point in driving DI technology fostering such horizontal integration in the emerging DI ecosystem
• We are by no means convinced that the new DI ecosystem will be successfully set up in the coming years and we have to prepare for all of those potential outcomes:
  • The DI ecosystem will be stepwise implemented and delivers value as hoped for
  • The DI ecosystem is a failure and nothing really comes out of it
  • The DI ecosystem is established but not in a way we hoped for
• We are primarily interested in actions we can take as NREN or its umbrella organisation GEANT

Approach

1. split the work aligned with the Trust Over IP Model
   as per https://trustoverip.org/toip-model/, i.e split into four layers in two stacks → eight work items: T1, G1, T2, G2,... T4, G4
   

2. elaborate each item regarding the following aspects:

   Subchapter	Description	Example
   The work item	a brief description of the topic at hand
   Transformative aspects	What will potentially change with respect to our current way of delivering value in general and with a particular view to our ecosystem? Include a critical review of our existing ecosystem services
   Opportunities	Describe use cases in our ecosystem that could potentially benefit from an emerging DI ecosystem Describe assumptions / requirements towards other players / outcomes etc. to make it deliver value to our ecosystem Describe actions we need to fulfil as a community (ecosystem) to get such value delivered to our ecosystem
   Risks	Describe potential situations leading to a failure to deliver value to our ecosystem This could be linked to external developments but also to our inability to fulfil above actions
   Engagements	Describe (crowdsourced within our group) prior or ongoing activities in our ecosystem relevant to the topic at hand

   
   

3. characterise the work items for further individual treatment
   

   Tech Item	Characterisation	Governance Item	Characterisation
   T4	Ecosystem use cases	G4	Ecosystem governance
   T3	Credentials/Identity information exchanged	G3	Governance of credentials/Identity information exchanged
   T2	Protocol layer, Wallets	G2	Governance of protocols and wallets
   T1	Registry layer, "Metadata"	G1	Registry/"Metadata" governance
