chore: version package for release

[github-actions]

This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

@_linked/core@1.2.0

Minor Changes

• #9 381067b Thanks @flyon! - Replaced internal query representation with a canonical backend-agnostic IR AST. SelectQuery, CreateQuery, UpdateQuery, and DeleteQuery are now typed IR objects with kind discriminators, compact shape/property ID references, and expression trees — replacing the previous ad-hoc nested arrays. The public Shape DSL is unchanged; what changed is what IQuadStore implementations receive. Store result types (ResultRow, SelectResult, CreateResult, UpdateResult) are now exported. All factories expose build() as the primary method. See documentation/intermediate-representation.md for the full IR reference and migration guidance.

• #14 b65e156 Thanks @flyon! - Add SPARQL conversion layer — compiles Linked IR queries into executable SPARQL and maps results back to typed DSL objects.

  New exports from @_linked/core/sparql:

  • SparqlStore — abstract base class for SPARQL-backed stores. Extend it and implement two methods to connect any SPARQL 1.1 endpoint:

    import { SparqlStore } from "@_linked/core/sparql";
    
    class MyStore extends SparqlStore {
      protected async executeSparqlSelect(
        sparql: string
      ): Promise<SparqlJsonResults> {
        /* ... */
      }
      protected async executeSparqlUpdate(sparql: string): Promise<void> {
        /* ... */
      }
    }

  • IR → SPARQL string convenience functions (full pipeline in one call):

    • selectToSparql(query, options?) — SelectQuery → SPARQL string
    • createToSparql(query, options?) — CreateQuery → SPARQL string
    • updateToSparql(query, options?) — UpdateQuery → SPARQL string
    • deleteToSparql(query, options?) — DeleteQuery → SPARQL string

  • IR → SPARQL algebra (for stores that want to inspect/optimize the algebra before serialization):

    • selectToAlgebra(query, options?) — returns SparqlSelectPlan
    • createToAlgebra(query, options?) — returns SparqlInsertDataPlan
    • updateToAlgebra(query, options?) — returns SparqlDeleteInsertPlan
    • deleteToAlgebra(query, options?) — returns SparqlDeleteInsertPlan

  • Algebra → SPARQL string serialization:

    • selectPlanToSparql(plan, options?), insertDataPlanToSparql(plan, options?), deleteInsertPlanToSparql(plan, options?), deleteWherePlanToSparql(plan, options?)
    • serializeAlgebraNode(node), serializeExpression(expr), serializeTerm(term)

  • Result mapping (SPARQL JSON results → typed DSL objects):

    • mapSparqlSelectResult(json, query) — handles flat/nested/aggregated results with XSD type coercion
    • mapSparqlCreateResult(uri, query) — echoes created fields with generated URI
    • mapSparqlUpdateResult(query) — echoes updated fields

  • All algebra types re-exported: SparqlTerm, SparqlTriple, SparqlAlgebraNode, SparqlExpression, SparqlSelectPlan, SparqlInsertDataPlan, SparqlDeleteInsertPlan, SparqlDeleteWherePlan, SparqlPlan, SparqlOptions, etc.

  Bug fixes included:

  • Fixed isNodeReference() in MutationQuery.ts — nested creates with predefined IDs (e.g., {id: '...', name: 'Bestie'}) now correctly insert entity data instead of only creating the link.

  See SPARQL Algebra Layer docs for the full type reference, conversion rules, and store implementation guide.
