기능

• Marker-like PDF Chunking for AI and RAG Workflows - Introduced Marker-like PDF chunking for AI-driven document processing. This enables splitting PDF documents into semantic DocumentChunk objects that can be used in Retrieval-Augmented Generation (RAG), semantic search, and vector indexing workflows. The new API provides extension methods on Document:
  • GetChunksAsync - Converts a PDF to Markdown and splits it into DocumentChunk objects.
  • IngestAsync - Runs the complete pipeline: chunks the document, generates embeddings, and upserts records into a vector store.
• Chunking behavior can be configured with ChunkingOptions, including MaxChunkSize and OverlapSize. The ingestion pipeline is based on Microsoft.Extensions.AI and Microsoft.Extensions.VectorData abstractions, so it can be used with different embedding providers and vector stores.
• Signing with Certificate and TSA - Extended digital signing support for workflows that require certificate-based signatures together with a timestamp authority (TSA). Added new constructor overloads for PKCS7 and PKCS7Detached that accept TimestampSettings.
