Dear eduGAIN,

 

Thank you for your feedback on the EC support attribute for the CoCo.

 

Based on the feedback and discussion with related people I have prepared the attached updates (changes highlighted)

- Entity Category spec for the Code of Conduct

- SAML2 metadata spec for the Code of Conduct

 

Please provide any comments and feedback before the end of August.

I will then ask Brook to bring the specs to eduGAIN steeging group.

 

Cheers,

Mikael

Subject: Entity category support attribute for Data Protection CoCo?

 

Dear eduGAIN,

 

Currently, the GÉANT Data protection Code of Conduct defines an entity category attribute just for SPs[1]. No entity category support attribute for IdPs is defined.

 

I would like to ask the community’s opinion if there is a need to complement the CoCo specification by defining also the EC support attribute for IdPs. The semantics would be “As an IdP, I’m willing to release attributes to the SPs committed to the GÉANT Data protection Code of Conduct”. The use case would obviously be assembling a proper IdP Dicovery service in the SP side.

 

The reason for the hesitation so far has been a possible interference of the multiple EC support attributes of an IdP, but that issue has been discussed in the REFEDS list [2]. The conclusion was that if an IdP asserts support to multiple ECs, they are interpreted separately and independently. For instance, if an IdP has both the CoCo and R&S support attributes, it means “this IdP releases attributes to an SP that asserts R&S and, independent of that, to an SP that asserts CoCo”.

 

The CoCo support attribute would still leave an opportunity to the IdP to decide,

- what is the maximum list of attributes to release (although the cookbook gives an idea[3])

-  if the IdP wants to make an exception for some SPs (I think we can’t avoid this anyway).

 

Looking forward to receiving your input!

 

Cheers,

Mikael (the CoCo flywheel)
