They are +not yet published to NuGet.org. No DataIngestion bridge, enrichment package, +public renderer, companion Documents framework, or core Markdown conversion +is introduced here. + +| Package suffix | Source | Input | +|---|---|---| +| `PdfPig` | Native PdfPig | PDF | +| `AzureContentUnderstanding` | Azure AI Content Understanding SDK | Service-supported documents | +| `AzureDocumentIntelligence` | Azure Document Intelligence SDK | Service-supported documents | +| `Mistral` | Mistral OCR on Azure AI Foundry | Service-supported documents | +| `Vision` | Borrowed Microsoft.Extensions.AI `IChatClient` | Images and rasterized PDF pages | + +All package IDs start with `CommunityToolkit.DocumentExtraction.` and target +`net8.0` and `net10.0`. Versions are centrally managed; the experimental core +dependencies currently require `10.10.0-review.20261101.2`. These core +prereleases are not released on a public package feed. Until the upstream +packages publish, the component uses a temporary, reproducible **public-source +prerequisite**, linked to [dotnet/extensions#7588](https://github.com/dotnet/extensions/pull/7588). + +`eng/Bootstrap-DocumentExtractionCore.ps1` fetches the full, unmodified public +`https://github.com/luisquintanilla/extensions.git` source at immutable commit +`e587de895203092a7dbd1c8e13161a9bec6d5a79`, verifies its tree +`b9b3540e4159e04b92b77015a0ab87b839b4867e`, and packs the four original owning +projects with SDK `10.0.401`. It does not replace upstream projects/imports or +use a moving build DLL. `Features=` disables the upstream debug-determinism +compiler feature which otherwise removes portable-PDB SourceLink. No extra +`ContinuousIntegrationBuild` or `ArtifactsDir` build override is applied. + +```powershell +.\eng\Bootstrap-DocumentExtractionCore.ps1 -DotnetPath C:\path\to\sdk-10.0.401\dotnet.exe +.\eng\New-DocumentExtractionNuGetConfig.ps1 ` + -CorePackageDirectory .\nuget\document-extraction-core ` + -OutputPath .\nuget\document-extraction-nuget.config +dotnet restore .\DocumentExtraction\DocumentExtraction.slnf ` + --configfile .\nuget\document-extraction-nuget.config +dotnet build .\DocumentExtraction\DocumentExtraction.slnf --no-restore -c Release +dotnet test .\DocumentExtraction\DocumentExtraction.slnf --no-build --no-restore -c Release +dotnet pack .\DocumentExtraction\DocumentExtraction.slnf --no-build --no-restore ` + -c Release --output .\nuget\document-extraction-providers +``` + +CI executes that same source bootstrap on Windows, uploads its actual nupkgs as +the same-run `document-extraction-core-source-packages` artifact, and restores +the Windows/Linux provider jobs from that artifact plus NuGet.org using an +isolated configuration. This is not a URL for historical CI binaries and does +not claim canonical cross-build byte equality. SDK installation remains isolated; +the bootstrap refuses dirty source checkouts or mismatched SDK/source identities. +Private review archives/configurations are not CI inputs or committed dependencies. +No package release, signing, or publishing job is enabled for this preview lane. + +The component's tests use real Azure SDK HTTP replay, controlled Mistral HTTP +handlers, fake chat clients, and generated native PDFs. They require no cloud +authentication, embedding calls, models, or downloads. PdfPig remains native-text +only; no ONNX inference success is claimed. + +## Representation and ownership + +Content is local `AIContent` within the full document/section/text/image/table/ +cell hierarchy. Documents and structural ancestors do not duplicate child text. +Source frames are registered explicitly, native observations retain their identity, +and polygons retain every vertex in order. SDK section pointers and table cell +spans are preserved. A missing original page number stays missing. + +Callers own input streams and supplied SDK, HTTP, and chat clients. Results and +artifacts are data-only, non-disposable values. Temporary resources are disposed +after exact response bytes and image content have been detached. Raw capture +defaults to false and distinguishes `Disabled`, `Unavailable`, and `Retained`. +Native observation inspection is independent of response capture and can still +contain sensitive data. No serialization of mapped or SDK objects is relabeled +original response content. Request extractor selection does not fabricate a +returned model identity. + +## Source attribution + +Native segmentation, bounding-box mapping, pluggable role resolution, and +rendering-resource/test patterns recover useful work authored by +[@luisquintanilla](https://github.com/luisquintanilla) in the closed, unmerged +[CommunityToolkit/AI#3](https://github.com/CommunityToolkit/AI/pull/3) +(`37b34b1fbf0a6f265257f4b46d75b687e3cf0684`) and +[CommunityToolkit/AI#14](https://github.com/CommunityToolkit/AI/pull/14) +(`f7ec65479ce9afe172579fb884d67f534dcf73e8`). +Provider-specific mapping and offline replay fixtures also adapt the retained +provider source supplied for this implementation.

The identifier labels the result; it is not a URL that the +provider fetches. Supply a readable stream and the actual media type. +`DocumentExtractionOptions.ExtractorName` selects an analyzer/model where the +provider supports it. Provider-specific options belong in `AdditionalProperties`; +unsupported options raise errors. + +## Work with the result + +`ExtractionDocument` contains sections and a hierarchy of text, images and +tables. Content is local to each element; structural ancestors do not repeat +their children's text. `EnumerateContent()` walks section elements in depth-first +order and yields non-section elements, including tables. It does **not** enter +table cells or return document/section-local payloads. Inspect `document.Content`, +section `Content` and table cells directly when you need those payloads. + +| Result | How to use it | +|---|---| +| Text | `ExtractionDocumentTextElement.Content` contains `TextContent`; read its `Text` and the element's optional role. | +| Tables | `ExtractionDocumentTableElement.Cells` exposes `RowCount`, `ColumnCount` and a `[row, column]` indexer. A cell can hold a text element or nested section, with spans and an optional role. Mistral and some vision results instead keep table-local Markdown in the table's `Content`. | +| Images | Read `ExtractionDocumentImageElement.Content` when image data is available. `AlternativeText` is a caption/description; `Text` is recognized image text, when supplied. | +| Sources | `document.SourcePages` describes source frames. Element `Sources` associate content with a page and any reported ordered polygon. Page numbers, dimensions or geometry can be absent. | +| Native data | `document.RawRepresentation` and `source.GetRawRepresentation()` expose backend-specific inspection objects where available. | + +### Read table cell content + +The cell indexer returns an actual anchor cell or null. Null means either an empty +position or one covered by another anchor's span; it is not an empty text cell. +Read `RowIndex`, `ColumnIndex`, `RowSpan` and `ColumnSpan` from non-null anchors +to understand the occupied range. An anchor can itself have null `Content`. + +Continuation of the example above. This walks sections and table anchor cells +explicitly, including section-valued mixed cell content and nested tables: + +```csharp +foreach (var page in document.SourcePages) +{ + Console.WriteLine($"Source {page.Identifier}, original page {page.PageNumber}"); +} + +foreach (var section in document.Sections) +{ + PrintElement(section); +} + +void PrintElement(ExtractionDocumentElement element) +{ + if (element.Content is TextContent text) + { + Console.WriteLine(text.Text); + } + if (element is ExtractionDocumentImageElement image && + image.Content is DataContent data) + { + Console.WriteLine($"{image.AlternativeText}: {data.Data.Length} image bytes"); + } + if (element is ExtractionDocumentSection section) + { + foreach (var child in section.Elements) + { + PrintElement(child); + } + } + else if (element is ExtractionDocumentTableElement table) + { + foreach (var cell in table.Cells) + { + if (cell is null) + { + continue; + } + + Console.WriteLine( + $"Cell ({cell.RowIndex}, {cell.ColumnIndex}), span {cell.RowSpan} x {cell.ColumnSpan}"); + if (cell.Content is { } content) + { + PrintElement(content); + } + } + } +} +``` + +Source capabilities vary: PdfPig supplies PDF block geometry; Azure services +supply their reported regions; Vision supplies page associations rather than +measured paragraph polygons. Check for data instead of assuming every provider +supplies the same level of detail. + +## Lifetimes, cancellation and middleware + +Dispose extraction clients when finished. Providers leave caller-supplied input +streams and SDK, HTTP or chat clients open. Returned documents require no +disposal; extracted image bytes and data remain usable after extraction. +Native inspection objects can be mutable and contain sensitive data, so avoid +treating them as a durable interchange format or logging them indiscriminately. + +Providers buffer input in memory.

Keep it alive until all +extractors using it are finished. Calls through one client are serialized at +inference/disposal; sharing a session across clients requires application-level +lifetime coordination. `GetService(typeof(InferenceSession))` returns the +unkeyed native session while the client is alive. +Do not dispose an owned session obtained through `GetService`; dispose its +extractor instead. + +## Result semantics and limitations + +- Accepts only `application/pdf`. This is **layout detection, not OCR**: + scanned pages can have picture/table regions but no recognized text. Use an + OCR-capable provider when text must be recognized from pixels. +- Each original page has a source frame, even when empty. Region polygons use + PDF points, bottom-left origin, relative to the effective crop **after** page + rotation. Coordinates are scaled from actual rendered pixel dimensions, not + an assumed DPI. Do not apply the crop offset or rotation a second time. + Non-default or indirect PDF `UserUnit` is unsupported and raises an error. +- A word belongs to at most one region: at least half of its axis-aligned area + must overlap; the largest overlap wins, then higher confidence. Unassigned + native words remain text blocks. Words centered outside the visible crop are + excluded. Text grouping uses PdfPig's nearest-neighbour word extraction and + Docstrum block segmentation; regions are ordered top-to-bottom, then + left-to-right. This is a geometric heuristic, not learned multi-column + reading order; rotated text can contain additional line breaks. +- `title` and `section_header` become text role `heading`; `page_header` and + `page_footer` become `pageHeader` and `pageFooter`. Plain `text` has no role. + Other text labels retain their Heron label. Native observations preserve the + original label and confidence, including regions without native text. +- A table region has native text in its local `Content` and a **zero-sized cell + grid**: the model does not reconstruct cells, spans or table structure. + A picture has measured sources and any associated native words in `Text`; + this package does not return a cropped image, image bytes, captions or OCR. +- Source references expose `PdfPigLayoutRegion` for model regions and PdfPig + `TextBlock` for unmatched text. `document.RawRepresentation` is a detached + `IReadOnlyList`, not an ONNX tensor/session or open PDF. +- `DocumentExtractionOptions.ExtractorName` must be absent or + `pdfpig-onnx-heron`. Unsupported selectors/additional properties fail + explicitly. Raw wire capture is unavailable because extraction is local; + native region observations are independent of raw-content capture. + +## Troubleshooting + +- **Model load/schema errors:** verify the exact file/hash and export above. + Missing, invalid or incompatible models never trigger a download or a + text-only fallback. +- **Native-library load errors:** check process architecture and both native + runtime asset sets, including Linux shared-library prerequisites. +- **Memory limits:** lower `RenderDpi` or process smaller PDFs; the model and + input buffer also consume memory. Native parsing/rendering failures propagate. +- **Cancellation:** tokens are checked during input copy, between pages, + preprocessing and mapping. In-flight ONNX runs receive a termination request. + Synchronous native PDF parsing/rendering cannot be interrupted mid-call, so + cancellation is not a hard wall-clock deadline. + +## Documentation and feedback + +- [Docling Heron model card](https://huggingface.co/docling-project/docling-layout-heron) +- [PdfPig document-layout analysis](https://github.com/UglyToad/PdfPig/wiki/Document-Layout-Analysis) +- [ONNX Runtime .NET API](https://onnxruntime.ai/docs/api/csharp/api/Microsoft.ML.OnnxRuntime.InferenceSession.html) +- [Provider comparison and shared result model](https://github.com/CommunityToolkit/AI/blob/main/DocumentExtraction/README.md) +- [Report a Toolkit issue](https://github.com/CommunityToolkit/AI/issues) + +The Toolkit package is [MIT licensed](https://github.com/CommunityToolkit/AI/blob/main/LICENSE). +PdfPig, Docnet/PDFium, ONNX Runtime and model weights retain their respective +licenses and notices; model weights are not included in this package. diff --git a/DocumentExtraction/src/PdfPig/README.md b/DocumentExtraction/src/PdfPig/README.md index f1d1561..18d6231 100644 --- a/DocumentExtraction/src/PdfPig/README.md +++ b/DocumentExtraction/src/PdfPig/README.md @@ -5,6 +5,11 @@ to a service**.

Do not apply the crop offset or rotation a second time. - Non-default or indirect PDF `UserUnit` is unsupported and raises an error. -- A word belongs to at most one region: at least half of its axis-aligned area - must overlap; the largest overlap wins, then higher confidence. Unassigned - native words remain text blocks. Words centered outside the visible crop are - excluded. Text grouping uses PdfPig's nearest-neighbour word extraction and - Docstrum block segmentation; regions are ordered top-to-bottom, then - left-to-right. This is a geometric heuristic, not learned multi-column - reading order; rotated text can contain additional line breaks. -- `title` and `section_header` become text role `heading`; `page_header` and - `page_footer` become `pageHeader` and `pageFooter`. Plain `text` has no role. - Other text labels retain their Heron label. Native observations preserve the - original label and confidence, including regions without native text. -- A table region has native text in its local `Content` and a **zero-sized cell - grid**: the model does not reconstruct cells, spans or table structure. - A picture has measured sources and any associated native words in `Text`; - this package does not return a cropped image, image bytes, captions or OCR. -- Source references expose `PdfPigLayoutRegion` for model regions and PdfPig - `TextBlock` for unmatched text. `document.RawRepresentation` is a detached - `IReadOnlyList`, not an ONNX tensor/session or open PDF. -- `DocumentExtractionOptions.ExtractorName` must be absent or - `pdfpig-onnx-heron`. Unsupported selectors/additional properties fail - explicitly. Raw wire capture is unavailable because extraction is local; - native region observations are independent of raw-content capture. - -## Troubleshooting - -- **Model load/schema errors:** verify the exact file/hash and export above. - Missing, invalid or incompatible models never trigger a download or a - text-only fallback. -- **Native-library load errors:** check process architecture and both native - runtime asset sets, including Linux shared-library prerequisites. The Managed - dependency alone cannot run inference; add the CPU or GPU package in the - application. CUDA also requires matching driver/CUDA/cuDNN installation. -- **Memory limits:** lower `RenderDpi` or process smaller PDFs; the model and - input buffer also consume memory. Native parsing/rendering failures propagate. -- **Cancellation:** tokens are checked during input copy, between pages, - rendering content operators, preprocessing and mapping. In-flight ONNX runs - receive a termination request. Individual synchronous parsing, codec and native - drawing calls cannot always be interrupted, so cancellation is not a hard - wall-clock deadline. - -## Documentation and feedback - -- [Docling Heron model card](https://huggingface.co/docling-project/docling-layout-heron) -- [PdfPig document-layout analysis](https://github.com/UglyToad/PdfPig/wiki/Document-Layout-Analysis) -- [PdfPig Skia rendering](https://github.com/BobLd/PdfPig.Rendering.Skia) -- [ONNX Runtime .NET API](https://onnxruntime.ai/docs/api/csharp/api/Microsoft.ML.OnnxRuntime.InferenceSession.html) -- [Provider comparison and shared result model](https://github.com/CommunityToolkit/AI/blob/main/DocumentExtraction/README.md) -- [Report a Toolkit issue](https://github.com/CommunityToolkit/AI/issues) - -The Toolkit package is [MIT licensed](https://github.com/CommunityToolkit/AI/blob/main/LICENSE). -PdfPig and PdfPig.Rendering.Skia are Apache-2.0; the DCT/JBIG2 filter packages -are Apache-2.0 and the JPX filter is BSD-2-Clause.

Structured mode requires a JSON object with a `pages` array; tables can contain addressed cells or table-local Markdown. Invalid output raises an error. +The private structured-response contract now uses **cell anchors and spans as +the only authority for table dimensions**. It no longer accepts `rowCount` or +`columnCount`, including in otherwise consistent responses. This intentional +pre-preview prompt/schema change does not change public types. Custom `Prompt` +values still replace the built-in instruction verbatim; structured mode always +enforces the current schema, so update custom instructions that request old fields. +Unknown or duplicate object properties are rejected, not silently discarded. + +Cell `rowIndex` and `columnIndex` are zero-based, including headers. Positive +`rowSpan`/`columnSpan` count occupied positions including the anchor and default to +one. A merged cell occurs once at its top-left anchor; header roles, null text, +empty text and literal text are retained. The grid extent is the maximum of +anchor plus span in each direction, not a second model prediction. An explicitly +observed blank cell must be emitted; absent positions remain unknown, not invented +blank observations. Sparse coordinates cannot bypass the **65,536 combined grid +positions per response** limit (including unobserved holes); oversized grids fail +before rectangular allocation. Each table also permits at most 65,536 anchors. +Negative indices, invalid spans, arithmetic overflow, duplicate anchors and +overlaps are errors with zero-based page/table/cell context.

Null `cells` is equivalent to +omitting it only when literal Markdown is supplied; null or omitted `cells` +without string Markdown is invalid. Non-null cell arrays combined with non-null +Markdown remain invalid, including empty arrays or empty Markdown. +Markdown-only tables remain literal table-local text with a zero-by-zero cell +grid; the provider does not reconstruct cells from it.

The development of three petroleum systems in the\nprovince is related to the tectonic history (Otto and Bailey, 1995; Ismail-\nZadeh and others, 1997; Martirosyan and others, 1998; Lindquist, 1999;\nFossum and others, 2001; O'Leary and others, 2004; Sliaupa and others,\n2006). The progressive closure of the Uralian Ocean in the Late Permian\nto Early Jurassic led to the formation of the Ural fold and thrust belt and\na west-facing foredeep along the fold belt. As much as 8 kilometers of\nsediment in the foredeep resulted in the thermal maturation of petroleum\nsource rocks into the gas-generation window and into the oil-maturation\nwindow west of the foredeep. Compressional deformation in the Creta-\nceous effectively ended the maturation process and resulted in erosion\nof as much as 800 meters. Mild compression in the Oligocene was\nlikely related to the far-field effect of the India-Eurasia plate collision.\nUncertainty in this assessment relates to the retention of oil or gas in the\nreservoirs following compressive deformation and migration.\n\n\n## Total Petroleum Systems and Assessment Units\n\nFor potential continuous oil and gas resources, the USGS defined\na Domanik Total Petroleum System (TPS) and a Denisov-Khoreyver\nDomanik Shale Oil Assessment Unit (AU) and an Izhma-Pechora\nDomanik Shale Oil AU within this TPS, an Ordovician-Lower Devonian\nComposite TPS with a Denisov-Khoreyver Shale Gas AU, and a Paleo-\nzoic Composite TPS with the Ural Foredeep Continuous Gas AU. Where\nthermally immature, shales of the Domanik TPS contain Type II kerogen,\nhave total organic carbon (TOC) content of as much as 20 weight per-\ncent, have hydrogen index (HI) values of as much as 700 milligrams of\nhydrocarbon per gram (mg HC/g) of organic carbon, and are as much as\n60 meters thick (Pairazian, 1993; Banks and others, 1997; Martirosyan\nand others, 1998; Abrams and others, 1999; Tuttle and others, 1999;\nFossum and others, 2001; He and others, 2012). The geologic model for\nthe Domanik TPS is for oil generated from Domanik shales to have been\npartially retained within the shales following migration. Ordovician-\nLower Devonian Composite TPS shales contain Type II kerogen, have\nTOC contents of as much as 5 weight percent, have HI values of as much\nas 660 mg HC/g of organic carbon, and are as much as 800 meters thick\n(Pairazian, 1993; Abrams and others, 1999; Fossum and others, 2001).\nThe geologic model for the Ordovician-Lower Devonian Composite TPS\nis for gas, generated from cracked oil within Ordovician, Silurian, and\nLower Devonian source rocks, to have been partially retained within the\nsource rocks following migration. The Paleozoic Composite TPS was\ndefined to include all petroleum generated from any of several source\nrocks, including Ordovician, Silurian, Devonian, Carboniferous, and\nPermian shales. The geologic model is for oil to have cracked to gas\nupon burial in the foredeep, and gas from these source rocks migrated\nlocally into low-permeability sandstones, forming a regional, continuous\ngas accumulation. Source rocks within this TPS are variable and contain\nType II and Type III kerogen, have TOC contents of as much as 6 weight\n\npercent, have HI values of as much as 580 mg HC/g of organic carbon,\nand are as much as 800 meters thick. Source rocks in this TPS possibly\ninclude coal beds (Ulmishek, 1982; Abrams and others, 1999).\n\nAssessment input data are summarized in table 1. Input data for\ndrainage areas, success ratios, and estimated ultimate recoveries are\ntaken from geologic analogs in the United States.\n\n\n## Undiscovered Resources Summary\n\nThe USGS quantitatively assessed shale oil, associated gas, and\ncontinuous gas resources in four assessment units (table 2) in the Timan-\nPechora Basin Province of Russia. For undiscovered, technically recover-\nable continuous resources, the mean totals are 1,425 million barrels of shale\noil (MMBO), or 1.4 billion barrels of oil, with an F95-F5 fractile range\nfrom 330 to 3,099 MMBO; 45,721 billion cubic feet, or 46 trillion cubic\nfeet of gas (BCFG), with an F95-F5 fractile range from 8,679 to 98,647\nBCFG; and 737 million barrels of natural gas liquids (MMBNGL) with an\nF95-F5 fractile range from 115 to 1,708 MMBNGL. Of the mean total of\n45,721 BCFG, about 78 percent, or 35,511 BCFG, is estimated to be in the\nUral Foredeep Continuous Gas AU.\n\n\nFigure 1.

The consuming feed generator +refuses missing, stale or mismatched canonical provenance. +Non-core dependency restore uses the public `dotnet-public` mirror already +configured by upstream, including its prerelease dependency band. The unchanged +Azure Document Intelligence SDK is not present on that mirror and is mapped +specifically to NuGet.org. If NuGet.org is inaccessible, explicitly supply an +existing verified local package source with +`-DocumentIntelligencePackageSource`; that source can supply only this SDK, +never any core package. No TLS checks are disabled or stale core identities used. +This is not evidence that the four review core identities are released on a feed. No replacement projects or copied production DLLs are used. +The SDK 11 prerequisite is limited to building these upstream projects. +Toolkit providers and applications continue to use SDK/runtime 10 and only +`net10.0`/`netstandard2.0` provider assets. The portable upstream dependency band +includes System.Text.Json 11 prerelease assets compatible with runtime 10; +it is not rewritten to an older band.

Restore the portable test profile before running it. All extraction checks are offline; the source/bootstrap and dependency restore need public network access. CI performs this on Windows and Linux with a same-run source-built core artifact. Artifacts expire and are not a public feed. -Formal upstream approval and released dependency versions remain prerequisites -for merging/releasing against stable contracts. +Documents and Extraction are present in the pinned official upstream source; +this does not establish availability of equivalent released package identities +on NuGet.org.
