- Add @lde/pipeline-void package with VOiD statistical analyzers - SparqlQueryAnalyzer for CONSTRUCT queries with template substitution - PerClassAnalyzer for two-phase class iteration to avoid timeouts - 16 SPARQL query files for dataset analysis - Add @lde/sparql-writer package for RDF output - SparqlUpdateWriter using INSERT DATA queries - FileWriter for Turtle/N-Triples/N-Quads files - Enhance @lde/task-runner-native - Add configurable working directory (cwd option) - Add graceful shutdown with SIGKILL escalation after timeout - Handle already-exited processes in stop() - Update @lde/sparql-qlever for new CLI names - IndexBuilderMain → qlever-index - ServerMain → qlever-server - Add waitForSparqlEndpointAvailable after server start - Add PipelineBuilder fluent DSL to @lde/pipeline - Builder pattern with withSelector(), addStep(), addWriter() - Helper functions: registry(), manual(), fileWriter(), sparqlWriter() - defineConfig() and loadPipelineConfig() via c12 - Update README files for task-runner packages
- Add optional logger support and byteSize check to distribution-downloader to detect incomplete downloads - Add DistributionAnalyzer to pipeline for probing dataset distributions - Remove duplicate Importer/ImportSuccessful/ImportFailed types from pipeline, now imports from @lde/sparql-importer - Add tests for byteSize detection and logger functionality - Update coverage thresholds to match actual coverage
- Add vite.config.ts to enable running tests via Nx - Fix test state isolation by resetting distribution properties in beforeEach - Set coverage thresholds to match actual coverage
Enable running tests via Nx. Coverage thresholds set to 0 since the only source file (index.ts) is excluded by base config.
- Add loadQuery() static method to PerClassAnalyzer for subclass reuse - Add ObjectClassAnalyzer, DatatypeAnalyzer, LanguageAnalyzer subclasses - Add VocabularyAnalyzer decorator that enriches with void:vocabulary triples - Add withProvenance() utility for PROV-O metadata triples - Add tests for all new modules (16 new tests, 25 total)
… in PerClassAnalyzer - Add ExecuteOptions with endpoint and bindings to SparqlConstructExecutor.execute() - Bindings are applied as string replacements before standard template substitution - Refactor PerClassAnalyzer to delegate CONSTRUCT execution to SparqlConstructExecutor - Keep SELECT class query with its own substituteSelectTemplates method - Add SparqlConstructExecutor, collect(), and related types to @lde/pipeline
- Remove vite.config.ts and vitest.config.ts from include in distribution-downloader and wait-for-sparql tsconfig.spec.json - Fixes typecheck errors caused by vite.base.config.ts being outside rootDir
…rd Logger interface - Define Logger interface matching abstract-logging/pino shape - Add noopLogger default to eliminate optional chaining - No new dependencies; structurally compatible with pino BaseLogger
- Refactor SparqlQuery step to delegate to SparqlConstructExecutor - Refactor SparqlQueryAnalyzer to use executor + collect() - Add @lde/pipeline dependency to pipeline-void - Add n3 dependency to pipeline for collect() - Add sparql and distribution exports to pipeline index - Fix eslint vite.config ignore in distribution-downloader, wait-for-sparql - Update sparql-qlever coverage thresholds and QLever image
- Use void-ext:distinctLiterals instead of nde:distinctObjectsLiteral - Use void-ext:distinctIRIReferenceObjects instead of nde:distinctObjectsURI - Drop non-distinct total counts (no standard equivalent) - Remove nde: prefix dependency from query files
- Add unit tests for collect() utility (stream to Store) - Ignore tsconfig.tsbuildinfo and vite.base.config.d.ts artifacts
- Fix stale @lde/* dependency versions in pipeline-void, sparql-writer, sparql-qlever - Add fileParallelism: false to pipeline tests to prevent port conflicts - Fix sparql-writer mock type to satisfy TypeScript strict checks - Update coverage thresholds for Vitest 4 - Sync tsconfig references via Nx

- Create @lde/pipeline/analyzer subpath export with Analyzer, BaseAnalyzer, Success, Failure, and re-exported NotSupported from step.ts - Delete pipeline-void's local analyzer.ts; re-export from @lde/pipeline/analyzer - Update concrete analyzers to import from @lde/pipeline/analyzer - Remove PipelineNotSupported alias workaround, use shared NotSupported directly - Update coverage thresholds to reflect removed source file
…void - Extract substituteQueryTemplates as shared function from SparqlConstructExecutor - Remove AnalyzableDataset; use ExecutableDataset from @lde/pipeline instead - Remove duplicate substituteSelectTemplates from PerClassAnalyzer - Add pipeline README - Update coverage thresholds
jest-dev-server waits for the TCP port but comunica's worker may still be loading the data file. Poll with an ASK query until the endpoint responds with HTTP 200 before returning.

- Replace hand-rolled polling loop with @lde/wait-for-sparql's waitForSparqlEndpointAvailable (uses p-retry with CONSTRUCT query) - Use UNION query to detect data in both default and named graphs - Change pipeline executor test port from 3002 to 3003 to avoid conflict with dataset-registry-client tests running in parallel
- The port conflict (3002) was the actual cause of flaky CI tests, not missing data readiness — fixed in previous commit - Remove wait-for-sparql dependency and UNION query workaround - Restore simple jest-dev-server TCP port check
- Use readQueryFile() from @lde/pipeline in pipeline-void analyzers instead of reimplementing file reading with readFile + toString - Use collect() from @lde/pipeline in PerClassAnalyzer instead of inline for-await loop - Merge @lde/sparql-writer into @lde/pipeline as subpath export @lde/pipeline/writer (Writer, FileWriter, SparqlUpdateWriter) - Delete standalone sparql-writer package - Update coverage thresholds
- Revert all sparql-qlever changes (not part of this PR's scope) - Document SPARQL test port allocations in CLAUDE.md to prevent future conflicts when Nx runs tests in parallel
…ith factories - Extract serializeQuads() into pipeline/writer/serialize.ts, used by both fileWriter and sparqlUpdateWriter instead of duplicated N3 wrappers - Replace DatatypeAnalyzer, LanguageAnalyzer, ObjectClassAnalyzer subclass files with factory functions in perClassAnalyzer.ts (-69 lines, +24) - Restore sparql-qlever tsconfig.json to main state - Update coverage thresholds for both packages
