Bare minimum presentation definition types

[mistermoe]

Changes

Added bare minimum presentation definition types needed for tbdex

Usage

pd := PresentationDefinition{
    InputDescriptors: []InputDescriptor{
        {
            Constraints: Constraints{
                Fields: []Field{
                    {
                        Path: []string{"$.credentialSchema[*].id"},
                        Filter: Filter{
                            Type:  "string",
                            Const: "https://schemas.tbdex.dev/KnownCustomerCredential"
                            
                        },
                    },
                    {
                        Path: []string{"$.issuer"},
                        Filter: Filter{
                            Type:  "string",
                            Const: "PFI_DID",
                        },
                    },
                },
            },
        },
    },
}

---

Added vc.credentialSchema and respective create option

Note

currently defaults credentialSchema.type to JsonSchema

Important

validation using these JSON Schemas will be added in a subsequent PR

Usage

claims := vc.Claims{"id": "1234"}
issuanceDate := time.Now().UTC().Add(10 * time.Hour)
expirationDate := issuanceDate.Add(30 * time.Hour)

cred := vc.Create(
    claims,
    vc.ID("hehecustomid"),
    vc.Contexts("https://nocontextisbestcontext.gov"),
    vc.Types("StreetCredential"),
    vc.IssuanceDate(issuanceDate),
    vc.ExpirationDate(expirationDate),
    vc.Schemas("https://example.org/examples/degree.json"),
)

FYI #131

[KendallWeihe]

format is an object no? are you in move fast and break things mode here? if so could you create a ticket to correct in a follow up?

[KendallWeihe]

on this same note, missing format in the InputDescriptor

[KendallWeihe]

also fields.optional and constraints.limit_disclosure

I'm guessing all of this was intentionally left out

[mistermoe]

Aye intentionally left out as it's not needed at the moment. Felt this was better than map[string]any on the tbdex side

[mistermoe]

@KendallWeihe : removed format for now! 9b78e78

few comments on type definitions but lgtm ✅
