Mapping of eIDAS SAML attribute names to OIDC claim names

[Torsten Lodderstedt]

Channeling through a proposal of Ross Armitt Little:

eIDAS specify these friendly names (Ref: file:///C:/Users/A182805/Downloads/eidas_saml_attribute_profile_v1.0_2.pdf):

"FamilyName"

"FirstName"

"DateOfBirth"

"PersonIdentifier"

"BirthName"

"PlaceOfBirth"

"CurrentAddress"

"Gender"

"LegalName"

"LegalPersonIdentifier"

"LegalAddress"

"VATRegistration"

"TaxReference"

"BusinessCodes"

"LEI"

"EORI"

"SEED"

"SIC"

‌

So with format/types used by eIDAS as well as names there are incompatibilities with OpenID equivalents:

address

place_of_birth

birth_family_name

birth_given_name

birth_middle_name

So if these are being requested in the OIDC IDA framework it is needed that there is a mapping with eiDAS claims. Maybe this should be noted in the specification?

For OpenID specified friendly names we could more easily do a one to one mapping with:

"given_name",

"family_name",

"birthdate",

I would suggest to document the mapping in our Wiki or a small additional spec (which could also define eIDAS-specific identifiers).
