# DK-WS 1: Collective Notes #

[Sharing](https://hackmd.io/@HPC1-Outreach/Byx-DpMSK/edit)

ucloud is generic consumer; 

metadata index of different data sets

standard

interface to api to harvest 

procedure for accessing the individual data sets

single point of entry (where can i get data access)

__data hub__

demonstrate that this is possible, then the data providers is less important

## Data Finder ## to 

- FAIR metadata

eudat b2: https://b2share.eudat.eu/ (lack quality assessment and bias analysis), large hotchpot of data


- AAU provides infratructure and services including what would be needed for DaaS provided an agreement is in place.

- we need integration between Data Finder and AAU

- Data Finder must be transparant for AAU and SDU.

- Live data would be placed at AAU OR SDU

- the new "udbud" regarding a national "data management system" might be relevant for DaaS


- No up front requirement on the data providers
 
- It's imposible to find machine understandable common denominators for the the national and Nordic data colelctions

- automatisering af ETL til AAU kræver mere end det samme for SDU.

- Autentifikation: WAYF + ssh nøgle. hvordan kan det kobles med en data-nøgle udstedt af eller til fx KB.

- Hvad med format af data?

 - comp.lang.?
 - dataformat er enten bestemt af API eller som resultat af en dialog.
 
- Det er en manuel proces at opsøge data providers og arrangerer med dem eller lære om deres API'er m.m.


## Data passport ##

WAYF: human to service, OAUTH (open id connect used by aaai system currently)
    - some way to authorize machine-to-machine

- encryption
- governance model
- global alliance for genomic data
- [global alliance](https://www.ga4gh.org/genomic-data-toolkit/data-security-toolkit/)

- ELIXIR for cultural heritage data https://elixir-europe.org/
- collection of royal libraries issue passport
- central organization for libraries

- [XROAD](https://x-road.global/), governance and access to data, The free and open source data exchange layer software, federation across difference countries

- Focus ONLY on royal libraries
- Source of trust, X-Road, central source of trust, 
- Organization that are the data controllers

- public; 

- royal libraries have their own governance; central layer for governance

- ucloud is not there to impose rules; just set baseline for a common language --> complete decentralization
    - the right interface
    - move responsibility to royal library

- internal procedure;

- researcher searches for data :: point researcher for internal procedure at at royal library :: get access in specified system (pre-authorized ) :: 


- __express decision in common governance system (json token), what the royal library is given access to (royal library issue/revoke)__
- __royal library agrees on what is a proper system(-s)__


- WAYF access for libraries (Nordics, each nation has their federation access, nationally through WAYF for dk), eduGAIN:
    * All Trust WAYF, FIDE ... (identify for all organization)
    * all parties agree on an identity provider that we trust
    * some standard way/standard language to put decision about the WAYF


__passport__ a standard for sharing data; libraries need to enforce the passport; demonstrate in ucloud


## Federated Learning ##
- use case for 1 and 2 (if 1 and 2 in place, then 3 is trivial)


## Quality assessment and bias analysis

- who creates the quality and bias information — not UCloud as this would be a huge task
- 
## Data provider ##



## Encryption ##

from the data provider, at the level of the data, organizations agree on the format for data exchange.
