Struct Field 

pub struct Field {
    pub name: String,
    pub iri: String,
    pub label: Option<String>,
    pub value_type: ValueType,
    pub link_target: Option<String>,
    pub cardinality: Cardinality,
    pub is_builtin: bool,
    pub data_model: Option<String>,
}

A field belonging to a resource-type, as surfaced by dsp vre resource-type describe.

Carries identity (name + iri), server-supplied label, the field’s value_type (see ValueType), an optional link_target (the target resource-type local name, Some iff value_type == ValueType::Link), cardinality, a flag marking system (built-in) fields, and the source data_model name (for cross-DM tagging). No serde derive: wire deserialization stays in src/client/http.rs. See ADR-0001 / ADR-0008 and the CONTEXT.md “Field” / “Value Type” / “Cardinality” entries.

Fields

name: String

Short name of the field (e.g. hasTitle), derived from the property IRI.

iri: String

Full IRI of the field’s property (e.g. http://api.dasch.swiss/ontology/0801/beol/v2#hasTitle).

label: Option<String>

Server-supplied human label (rdfs:label), if any. None for system built-in fields whose property node is not fetched, and for fields left best-effort after a failed sibling-ontology fetch.

value_type: ValueType

The kind of value this field holds (text, integer, link, …).

link_target: Option<String>

The local name of the link target resource-type (e.g. Book, person). Some iff value_type == ValueType::Link; None for all other value types. This invariant is asserted in unit tests — the type does not enforce it structurally.

cardinality: Cardinality

Cardinality constraint: how many values the field may / must carry.

is_builtin: bool

true iff the field’s property CURIE prefix is a system namespace (knora-api, knora-base, rdf, rdfs, owl, salsah-gui, standoff, xsd). System fields are hidden by default; revealed with --include-builtins (Decision 3).

data_model: Option<String>

Source data-model name for the field’s property. Some with the data-model short name for project-defined and cross-DM fields (e.g. Some("biblio") for a biblio: property on a beol class); None for system built-ins (system-namespace prefix). The renderer emits a [from <dm>] tag when Some(x) and x differs from ResourceTypeDetail.data_model (Decision 10).
