Sylin.Koan.Data.Vector.Abstractions

Supported provider-neutral contracts behind Koan's Entity Vector runtime and provider packages.

Provider-neutral contracts for Koan vector search: adapter factories, repositories, capabilities, query and match shapes, export batches, schema descriptions, and provider-selection annotations. Referencing this package alone does not register a vector runtime or select a backend.

Install

dotnet add package Sylin.Koan.Data.Vector.Abstractions

Application developers normally reference Sylin.Koan.Data.Vector and a provider. Reference Abstractions directly when authoring a vector provider, shared query library, or projection that must not activate the runtime.

Smallest meaningful use

A provider-neutral library can construct the exact query handed to every vector repository:

using Koan.Data.Vector.Abstractions;

var query = new VectorQueryOptions(
    Query: embedding,
    TopK: 10,
    SearchText: "annual revenue",
    Alpha: 0.65);

Provider authors implement IVectorAdapterFactory and return IVectorSearchRepository<TEntity,TKey> instances. VectorAdapterAttribute is the explicit entity-level provider request; VectorCaps describes optional repository behavior without pretending every backend has the same guarantees.

Guarantees and boundaries

  • This package depends on entity/filter/naming vocabulary from Sylin.Koan.Data.Abstractions; it does not depend on Data.Core, dependency injection, the vector runtime, or any provider client.
  • Query options express intent. Hybrid text, filtering, continuation, export, flush, and embedding retrieval remain provider capabilities and may be unsupported.
  • Repository default methods fail with NotSupportedException for optional operations rather than simulating them.
  • Provider election, memoization, physical collection naming, active-participation health, and entity facades belong to Sylin.Koan.Data.Vector.
  • Score scale, consistency, indexing latency, dimensionality, and distance behavior are backend guarantees; this package does not normalize them into false equivalence.

See TECHNICAL.md for the complete SPI and schema boundary.
