# Schemas

Schemas define credential attribute names and attribute types. Indicio Proven uses standards based credential schemas, such as ICAO-DTC, mDL, etc. or custom schemas. This acts as a sort of blueprint of what the verified credential will contain. The scheme outlines the basics of what data is required to truely identify the person being presented via VC. 

For example: the scheme will require Name, DOB, Issue date of the ID used to make the credential

Any information that can be conveyed through a credential schema is now verifiable, along with the source of that information. Trust lists for issuers and complex information flows and approvals are managed by machine-readable governance files directly sent to the agent software of each participant in the credential ecosystem.
