The article titled "Tables in PDFs for RAG: Don’t Flatten the Grid" discusses Enterprise Document Intelligence, presenting a diagnostic and five composable operations rather than a decision tree. It appears in the Vol.1 #B4 issue of the publication and was first posted on Towards Data Science.

Enterprise Document Intelligence [Vol. 1 #7sexies] - The unit of retrieval doesn’t have to be a page or a paragraph.
Enterprise Document Intelligence [Vol. 1 #9A] - Same paper, same question as Article 1.
The article discusses a method for handling a folder of unrelated PDFs as a single long document with a nested outline. It highlights that without shared fields, an index cannot be built, so the approach uses one summary line per file and each file’s own table of contents, with retrieval routes extending down two levels. This structure enables retrieval-augmented generation (RAG) across multiple documents.
