LangChain as RAG Knowledge Fabric overview
LangChain as a RAG-based knowledge fabric implementation. Provides the full pipeline from document loading (100+ loaders for PDFs, web pages, databases, APIs) through text splitting, embedding, vector storage, and retrieval chain construction. LangChain is not a knowledge store itself but an orchestration layer that turns any combination of document sources and vector stores into a queryable knowledge fabric. Retrieval chains compose retriever + LLM into a question-answering system grounded in organizational knowledge.

notes
LangChain's strength as a knowledge fabric is flexibility — it can
compose any combination of document sources, embedding models, vector
stores, and retrieval strategies. The LangChain Expression Language (LCEL)
enables declarative retrieval chain construction. The trade-off is
complexity — LangChain adds abstraction layers that can obscure the
underlying retrieval behavior and make debugging harder.
