## `create_presentation_from_credentials.json`
Vectors for creating a Presentation Submission from a given Presentation Definition and set of VC JWTs.

### Input
| Property | Description |
|---------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `input.presentationDefinition` | the input [presentationDefinition](https://identity.foundation/presentation-exchange/#presentation-definition) showing the requirements used for this getting an example WA license |
| `input.credentialJwt` | the input [verifiable credential secured as a JWT](https://www.w3.org/TR/vc-data-model/#json-web-token) that corresponds to the presentationDefinition to fulfill it and do a full presentation exchange |
| `output.presentationSubmission` | the expected [presentationSubmission](https://identity.foundation/presentation-exchange/#presentation-submission) when the `inputs` are processed by the `createPresentationFromCredentials` method. |

the value of `input` is a an object with `presentationDefinition` and the corresponding `credentialJwt`
## `select_credentials.json`
Vectors for selecting a subset of VC JWTs from a given set that satisfy a given Presentation Definition

| Property | Description |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `presentationDefinition` | the input [presentationDefinition](https://identity.foundation/presentation-exchange/#presentation-definition) showing the requirements used for this getting an example WA license |
| `credentialJwt` | the input [verifiable credential secured as a JWT](https://www.w3.org/TR/vc-data-model/#json-web-token) that corresponds to the presentationDefinition to fulfill it and do a full presentation exchange

| `input.presentationDefinition` | the [presentationDefinition](https://identity.foundation/presentation-exchange/#presentation-definition) describing the required credentials. |
| `input.credentialJwts` | a set of [verifiable credentials secured as a JWT](https://www.w3.org/TR/vc-data-model/#json-web-token) |
| `output.selectedCredentials` | the expected [VC JWTs](https://identity.foundation/presentation-exchange/#presentation-submission) that satisfy the input presentation definition. If the set of VC JWTs do not satisfy the presentation definition, `output.selectedCredentials` is an empty array. |

### Output
## `validate_definition.json`
Vectors for validating whether a Presentation Definition is valid or not

the value of `output` is an object that contains the following properties
| Property | Description |
|--------------------------------|--------------------------------------------------------------------------------------------------------------------------|
| `input.presentationDefinition` | the [presentationDefinition](https://identity.foundation/presentation-exchange/#presentation-definition) to be validated |
| `errors` | `true` is the presentation definition is NOT valid. `false` otherwise. |

| Property | Description |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `presentationSubmission` | the expected [presentationSubmission](https://identity.foundation/presentation-exchange/#presentation-submission) when the `inputs` are processed by `createPresentationFromCredentials`. |
## `validate_submission.json
Vectors for validating whether a Presentation Submission is valid or not

| Property | Description |
|--------------------------------|----------------------------------------------------------------------------------------------------------|
