}

The immutable stored body of an ACDP context (RFC-ACDP-0002).

Contains producer-controlled fields (covered by the producer signature) plus registry-assigned identity fields (ctx_id, lineage_id, origin_registry, created_at) which rely on registry honesty in v0.1.0.

The hash/signature preimage is ProducerContent: the Body with content_hash, signature, and the registry-assigned identity fields removed. See RFC-ACDP-0001 §5.7.

Fields

ctx_id: CtxId

lineage_id: LineageId

origin_registry: String

created_at: DateTime<Utc>

content_hash: ContentHash

signature: Signature

version: u32

supersedes: Option<CtxId>

agent_id: AgentDid

contributors: Vec<AgentDid>

title: String

context_type: ContextType

data_refs: Vec<DataRef>

derived_from: Vec<CtxId>

visibility: Visibility

audience: Option<Vec<AgentDid>>

acdp_version: Option<String>

description: Option<String>

summary: Option<String>

Producer-supplied summary for search results (≤ 1000 chars). Part of ProducerContent — included in the content_hash preimage.

tags: Option<Vec<String>>

domain: Option<String>

expires_at: Option<DateTime<Utc>>

data_period: Option<DataPeriod>

metadata: Option<Value>

schema_uri: Option<String>

extensions: Map<String, Value>

Forward-compatible carry-through of unknown producer-controlled fields (e.g. v0.1’s priority). Including these in the typed model is required for serde_json::to_value(body) → JCS → SHA-256 to reproduce the original content_hash. Without flatten, a v0.1.0 consumer reading a v0.1 body would silently drop the new field and compute a different hash, falsely rejecting the body.

Trait Implementations

impl<'de> Deserialize<'de> for Body

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Body
