| # Opendoor Financial Event Knowledge Graph — pipeline data |
|
|
| The gitignored `data/` tree of the `Prototyping-Financial-Knowlege-Graph` repository, published |
| so a second machine can regenerate the graph without re-fetching EDGAR. |
|
|
| **This dataset is the data half only.** The code, configuration, ontology and recorded |
| provider answers live in the repository. Read [Reproducing the graph](#reproducing-the-graph) |
| before use — at the commit this snapshot was taken from, the repository alone **cannot** |
| project this run, and the reason is recorded below rather than left to be discovered. |
|
|
| Anchor company: **Opendoor Technologies Inc.** (CIK `0001801169`, Nasdaq: OPEN). Source: |
| SEC EDGAR. |
|
|
| ## What is here |
|
|
| 994.5 MiB across 2,755 files (`1,042,852,388` bytes). Every path keeps its repository-relative |
| name, so downloading into the repository root puts each file where the pipeline expects it. |
|
|
| | Path | Size | Contents | Role | |
| | --- | --- | --- | --- | |
| | `data/raw/sec/` | 746 MB | 2,128 files — SEC source bytes, original filenames, per-filing `_filing.json` | Input to normalization | |
| | `data/normalized/sec/` | 105 MB | 588 files — per-document JSON + passages JSONL | Input to extraction | |
| | `data/normalization_catalog/` | 41 MB | `passages.jsonl`, `documents.jsonl`, `selection.jsonl`, `issues.jsonl` | **Input to the graph** | |
| | `data/extraction_runs/extract-v1-lexical-7f72d6172630/` | 33 MB | 7 catalogs + `manifest.json` + `lane_outputs.jsonl` + `report.md` + `run.complete` | **Input to the graph** | |
| | `data/graph_runs/graph-v1-eeba753149e9/` | 74 MB | `nodes.jsonl`, `edges.jsonl`, `manifest.json` | Graph output — for Neo4j load and byte-comparison | |
| | `data/catalog/` | 1.9 MB | `filings.jsonl`, `artifacts.jsonl` | Derived acquisition index | |
| | `data/normalization_reports/`, `data/normalization_runs/`, `data/reports/`, `data/runs/` | 1.4 MB | Per-run reports and issue files | Diagnostics | |
| | `provenance/ontology_definitions/` | 88 KB | All 12 ontology YAML files as they were when the run was produced | See [Reproducing the graph](#reproducing-the-graph) | |
| | `provenance/CODE_STATE.txt` | 4 KB | Commit, branch, and the uncommitted-file list at snapshot time | Provenance | |
| | `MANIFEST.sha256` | 250 KB | `sha256 size path` for all 2,755 files, sorted by path | Transfer verification | |
|
|
| `data/` is only two files away from being the graph's whole input: `graph.core.inputs.load_run` |
| opens the extraction run directory and `normalization_catalog/{passages,documents}.jsonl`, and |
| nothing else. Everything above those two rows exists so earlier stages can be replayed. |
|
|
| ### Deliberately excluded |
|
|
| | Excluded | Size | Why | |
| | --- | --- | --- | |
| | `data/superseded_runs/extract-v1-lexical-2422c4252c07/` | 33 MB | Superseded extraction run | |
| | `data/graph_runs/graph-v1-886059d862ce/` | 74 MB | Projected from that superseded run (projection 1.1.0) | |
| | `.env` | — | Local Neo4j password. `.env.example` is in the repository | |
|
|
| `data/` was scanned for credential patterns before upload; the only provider record in any |
| manifest is a local model filename (`Qwen3.5-9B-Q4_K_M.gguf`) with `provider_calls_permitted: 0`. |
|
|
| ## Corpus and run facts |
|
|
| All values below are read from the shipped manifests, not restated from repository docs. |
|
|
| | Layer | Measured | |
| | --- | --- | |
| | Acquisition | 109 filings, 2,019 artifacts | |
| | Normalization | 294 documents, 12,442 passages (1,935 table); `corpus_id 294d-12442p-9992c4eb1888` | |
| | Extraction | run `extract-v1-lexical-7f72d6172630`, created 2026-08-03T13:33:47Z | |
| | — candidates | 11,848 (153 yielded a claim, 11,695 did not) | |
| | — claims / observations | 2,714 / 2,704 | |
| | — events / relationships | 6 / 4 | |
| | — issues / rejected claims | 17,130 / 49 | |
| | Graph | run `graph-v1-eeba753149e9`, projection `1.2.0`, created 2026-08-03T13:34:46Z | |
| | — nodes | 28,836 — Issue 17,127, Passage 8,776, Observation 2,704, Document 185, Metric 26, Entity 9, Event 6 | |
| | — edges | 35,600 — FOUND_IN 17,130, PART_OF 8,776, EVIDENCED_BY 2,710, HAS_OBSERVATION 2,704, OBSERVATION_OF_SUBJECT 2,704, CONCERNS_METRIC 1,523, DISTINCT_FROM 36, PARTICIPATES_IN 10, others 7 | |
| |
| Ontology: `real_estate_marketplace_v1`, `definition_hash 337e0e59534da0d2eb3235152af3d48f0510cdb391feed27956a4e80b0858af2`. |
| Extraction code commit: `c59818e4a775103c94f3438306c051b66ef54387`. |
| |
| The extraction run replays 15 recorded provider answers rather than calling a model |
| (`mode: replay_only`). The answers are committed in the repository at |
| `benchmarks/extraction/v1/answers/`, so extraction is reproducible offline — no API key, no |
| model download. |
|
|
| ## Getting the data |
|
|
| The repository is private, so a read token is required |
| (https://huggingface.co/settings/tokens). |
|
|
| ```bash |
| pip install huggingface_hub |
| hf auth login # paste a read token |
| |
| cd /path/to/Prototyping-Financial-Knowlege-Graph |
| hf download thelets/opendoor-knowledge-graph --repo-type=dataset --local-dir . |
| ``` |
|
|
| `--local-dir .` writes `data/...` directly into the repository root, which is where |
| `config/*.yaml` expects it. `provenance/`, `README.md` and `MANIFEST.sha256` land beside it and |
| are not read by any pipeline stage. |
|
|
| ### Verify the transfer |
|
|
| ```bash |
| sha256sum -c MANIFEST.sha256 |
| ``` |
|
|
| 2,755 lines, all `OK`. The manifest is independent of the per-run manifests, which carry their |
| own `catalog_digests` — checking both proves the run is internally consistent *and* that it |
| arrived whole. |
|
|
| ## Reproducing the graph |
|
|
| **The graph projection will refuse to run against a clean clone of commit `c59818e`.** This is |
| a measured fact, not a caution: |
|
|
| `graph/core/manifest.py:171` compares the loaded ontology's `definition_hash` against the one |
| the extraction run recorded and raises `GraphInputError` — *"the vocabulary changed under a |
| finalized run"* — when they differ. They differ: |
|
|
| | Ontology source | `definition_hash` | |
| | --- | --- | |
| | The tree that produced this run | `337e0e59…` (what `manifest.json` records) | |
| | Commit `c59818e` as committed | `e8d4af70…` | |
|
|
| The run was produced from a working tree carrying uncommitted changes to |
| `ontology/versions/real_estate_marketplace_v1/definitions/{claims,constraints,events}.yaml` |
| (+80 lines) and to `graph/core/models.py`, where `GRAPH_PROJECTION_VERSION` is `1.2.0` |
| uncommitted against `1.1.0` at `c59818e`. Since the graph run id derives from |
| `(projection_version, extraction_run_id, ontology_definition_hash)` |
| (`graph/core/manifest.py:137`), a clean clone would compute a different run id even if the |
| hash gate were passed. |
|
|
| Two ways forward: |
|
|
| 1. **Preferred — publish the code.** Commit and push branch |
| `impl/f0-factual-spine-contracts`, then check it out on the second machine. The ontology |
| YAML and the projection-version bump travel with it, both discrepancies disappear, and |
| `graph-v1-eeba753149e9` reprojects byte-for-byte. |
| 2. **Interim.** `provenance/ontology_definitions/` holds all 12 definition YAML files as they |
| were when the run was produced — the hash covers the whole directory, so the full set ships |
| rather than only the three that changed. Copying them over |
| `ontology/versions/real_estate_marketplace_v1/definitions/` restores |
| `definition_hash 337e0e59…` and satisfies the gate. This does **not** restore the |
| `GRAPH_PROJECTION_VERSION` bump, so the projection succeeds but mints a run id that is not |
| `graph-v1-eeba753149e9`. Use it to read the shipped graph, not to claim reproduction. |
|
|
| Loading the shipped `nodes.jsonl` / `edges.jsonl` into Neo4j needs neither workaround — that |
| output is already projected. |
|
|
| ## Provenance and licensing |
|
|
| Source documents are SEC EDGAR filings by Opendoor Technologies Inc., retrieved 2026-07-31. |
| US government edicts and EDGAR submissions are not subject to copyright in the United States; |
| the filings themselves are public disclosure. Raw bytes and original filenames are preserved |
| exactly, and every artifact carries a hash, a source URL and a fetch timestamp. |
|
|
| The derived layers — normalized passages, extraction catalogs, the ontology, and the projected |
| graph — are the work of this project. `license: other` is declared because the archive mixes |
| public-source documents with project-authored derivations rather than because any part is |
| restricted. |
|
|
| Extraction is imperfect by construction: this run holds 17,130 issues and 49 rejected claims, |
| and `rejected_claims.jsonl` carries **pre-validation model output** that was refused. Nothing |
| in `rejected_claims.jsonl` should be read as fact. None of this is investment advice. |
