Re: Proposed concepts for biometric data and political opinion data

Hi Georg. Thank you for the proposal. Below are my comments per concept 
from your submitted spreadsheets.

## Biometric concepts:

1) Fingerprint - exists
2) DNA - exists as pd:DNACode
3) Iris - doesn't exist, should be added as pd:Iris
4) Retinal - exists as pd:Retina
5) Facial - exists as pd:FacialPrint
6) Hand - doesn't exist, could be added as pd:Hand or pd:HandGeometr
7) Vein - doesn't exist, could be added as pd:VeinPattern
8) Voice - doesn't exist, should be added as pd:Voice
9) Gait - doesn't exist, should be added as pd:Gait

10) BiometricVerification - exists in eu-aiact:BiometricVerification, 
should be extended from dpv:BiometricVerification as the child concept 
of existing dpv:IdentityVerification (note dpv:BiometricAuthentication 
is a tech measure)
11) BiometricAuthentication - exists, see above

12) LivenessDetection - this should be added as a technical measure and 
not a purpose, and the description should focus on what it is detecting 
(ensuring captured biometrics are from a real person) and not on what it 
is preventing
13) Selfie Verification - this should instead be added as pd:Selfie 
under the existing pd:FacePrint and then used with LivenessDetection to 
indicate selfie verification

## Political concepts:

1) PublicPoliticalParticipation: Political opinions expressed through 
public participation and activism
2) PoliticalCommunication/Expression: Political opinions expressed 
through written and verbal communication
3) PoliticalSurveillanceData: Data collected specifically for monitoring 
or surveilling political activities

We already have pd:PoliticalOpinion and pd:PoliticalAffiliation. I don't 
think a further category showing where this is derived from should be 
necessary. I therefore propose PoliticalActivity as the concept to 
represent activities that are political in nature or indicate a 
particular opinion or affiliation regarding politics.

I do not think Political Surveillance Data should be a concept without a 
strict and normative definition, which I cannot find.

Regards,
Harsh
