Types

AtomicAttribute2023

@Serializable

@SerialName(value = "AtomicAttribute2023")

data class AtomicAttribute2023(val id: String, val name: String, val value: String, val mimeType: String) : CredentialSubject

VC spec leaves the representation of a single credential open to implementations. We decided to make a "generic" one, i.e. with custom name, value and mimeType.

Base64URLTransactionDataSerializer

object Base64URLTransactionDataSerializer : KSerializer<TransactionData>

According to "Transaction Data entries as defined in D3.1: UC Specification WP3" the encoding is JSON and every entry is serialized to a base64 encoded string

CredentialPresentation

@Serializable

sealed interface CredentialPresentation

CredentialPresentationRequest

@Serializable(with = CredentialPresentationRequestSerializer::class)

CredentialPresentationRequestSerializer

object CredentialPresentationRequestSerializer : JsonContentPolymorphicSerializer<CredentialPresentationRequest>

CredentialSubject

@Serializable

abstract class CredentialSubject

Base class for the subject of a VerifiableCredential, see subclasses of this class, e.g. AtomicAttribute2023.

CredentialToJsonConverter

object CredentialToJsonConverter

In OpenID4VP, the claims to be presented are described using a JSONPath, so compiling this to a JsonElement seems reasonable.
