Stratara.Abstractions

License: MIT.

Contract interfaces and wire-level POCO records for the Stratara framework. Library-safe — depends only on Microsoft.Extensions.DependencyInjection.Abstractions, Microsoft.Extensions.Logging.Abstractions, and Stratara.Contracts. No EF Core or message-bus runtime.

Use this when you need to reference Stratara types without pulling in any concrete implementation (Mediator runtime, EF Core, RabbitMQ, etc.). Typical consumers: handler/projection libraries that ship without a host.

Contents

  • Stratara.Abstractions.Mediator — IMediator, IRequest, IRequest<T>, ICommand, ICommand<T>, IQuery<T>, ICommandHandler<T>, IQueryHandler<T,R>, IPipelineBehavior<T>, IPipelineBehavior<T,R>, IAggregateScopedCommand.
  • Stratara.Abstractions.EventSourcing — IAggregationService, IEventSource, IEventStreamRepository, ISnapshotRepository, IEvent, IEvent<T>, IAggregateCreationEvent, IChangeSetHandler, EventChainAnchor, EventSubject, ConcurrencyException. Plus wire-types: EventStreamEntry, Snapshot.
  • Stratara.Abstractions.Persistence — IUnitOfWork, IWriteUnitOfWork, IReadUnitOfWork, ITransaction, IDbResolver.
  • Stratara.Abstractions.Outbox — ICommandOutboxDispatcher, IEventBundleOutboxDispatcher, IOutboxRepository. Plus wire-type OutboxEntry.
  • Stratara.Abstractions.Messaging — IMessageBus, IMessagingIdentifier, IEventBusConsumer, IEventBusPublisher.
  • Stratara.Abstractions.Session — ISessionContextProvider.
  • Stratara.Abstractions.Multitenancy — ITenantService, ICurrentUserService, ITenantScopedRequest, ICrossTenantAuthorizer, TenantAccessDeniedException.
  • Stratara.Abstractions.Projections — IProjectionReplayState.
  • Stratara.Abstractions.Security — IEncryptionFactory, IKeyStore, IMasterKeyProvider, ISecureBlobEncryptor, ISecureJsonSerializer. Plus wire-types: KeyScope, KeyMaterial, EncryptedData, DataSensitivityLevel, EncryptDataAttribute.
  • Stratara.Abstractions.Validation — IValidator<T>, ValidationResult, ValidationFailure, ValidationSeverity, StrataraValidationException.
  • Stratara.Abstractions.Entities — IEntity, IBucket, IHasRowVersion, IMultiTenant, ITenantEntity, IUserIdentity.
  • Stratara.Abstractions.BackgroundTasks — IBackgroundTaskQueue. Plus wire-types: BackgroundTaskInfo, BackgroundTaskStatus.
  • Stratara.Abstractions.Commands — IUpdateCommand.
  • Stratara.Abstractions.Authorization — RequireRoleAttribute, IAuthorizationProvider, AuthorizationException.

Why split

NuGet consumers without an event-sourcing host can adopt Stratara's CQRS contracts and authorization model without dragging in EF Core, RabbitMQ, or the WriteStore.

Package Downloads
Stratara.Sessions

ASP.NET Core middleware and provider for Stratara's Actor/Subject session model. Reads tenant and user from JWT claims (or X-Tenant-Id / X-Client-Id headers) and populates the ambient ISessionContextProvider for every request.
Stratara.Mediator

In-process mediator with DI-resolved handlers and pipeline behaviors for the Stratara framework. MediatR-style routing via typed wrapper cache, plus an authorizing decorator and a bucket-lock concurrency primitive.
Stratara.Security

Dependency-light key-store and envelope encryption for the Stratara framework. Production IKeyStore implementation (EnvelopeFileKeyStore) with KEK-wrapped, versioned per-scope DEKs (rotation + revoke + crypto-shred), a file-backed master-key provider, and an AES-GCM blob encryptor with purpose-bound associated data. References only Stratara.Abstractions + BCL crypto — no EF Core, RabbitMQ, Redis, or cloud SDKs.
Stratara.Validation

Vendor-neutral request validation for the Stratara framework — a mediator pipeline behavior that runs IValidator<T> implementations before the handler and throws an aggregated StrataraValidationException on failure. No FluentValidation dependency; an optional adapter is shipped separately.
Stratara.Resilience

Polly-based named resilience pipelines pre-wired for the Stratara framework's messaging and command/event dispatch paths. Three named pipelines registered via AddResiliencePipelines().

### Added

- **Event upcasting (`IEventUpcaster`).** Persisted events can now be transformed from an older
 on-disk schema into the shape the current event record expects, applied on read before the payload
 is deserialized. Register upcasters with `AddEventUpcaster<TUpcaster>()`; each implements
 `IEventUpcaster` (`SourceEventTypeName` / `TargetEventTypeName` plus `JsonNode Upcast(JsonNode)`) and
 they chain across successive schema versions (v1→v2→v3), including event-type renames — the source
 type no longer needs to exist in the assembly. Matching ignores the assembly `Version` segment, and
 a cyclic or duplicate-source chain is rejected. Hosts that register no upcasters are unaffected
 (transparent pass-through). Snapshots are not upcasted — change an aggregate's shape and rebuild its
 snapshots.

### Changed

- **Copyright holder corrected to the full legal name "Norbert Heinz Rosenwinkel"** in the `LICENSE`
 file and in the `Authors` / `Copyright` package metadata. No code or licensing-terms change — the
 license remains MIT.
