Class SemanticTag

Namespace

Kuestenlogik.Bowire.Semantics

Assembly

Kuestenlogik.Bowire.dll

Strongly-typed wrapper around the namespaced kind-string that names the semantic meaning of a schema field ("coordinate.latitude", "image.bytes", …).

public sealed record SemanticTag : IEquatable<SemanticTag>

Inheritance

object

SemanticTag

Implements

IEquatable<SemanticTag>

Inherited Members

object.GetType()

object.Equals(object, object)

object.ReferenceEquals(object, object)

Remarks

The set of valid values is open — extension authors register their own kinds at runtime — so this type does not constrain to a closed enum. What it does provide is type-safety on the wire (no random string can be confused for a semantic tag) and a single catalogue of the well-known kinds the framework ships with under BuiltInSemanticTags.

The special tag None (kind-string "none") is a real value, not a separate suppression flag: the resolver treats it as "the user explicitly said this is NOT something" and lets it override any auto-detector proposal beneath. IsNone distinguishes the suppression case from any other tag.

Constructors

SemanticTag(string)

Strongly-typed wrapper around the namespaced kind-string that names the semantic meaning of a schema field ("coordinate.latitude", "image.bytes", …).

public SemanticTag(string Kind)

Parameters

Kind string

Namespaced kind-string. Conventionally dotted (family.subkind) but the framework only requires a non-empty case-sensitive identifier; the dot is convention, not syntax.
