Dragon Finance Corpus — 3.93 TB across 12 product classes
A corpus of publicly available US and world financial data, compiled directly from primary sources and kept current by a continuous ingestion pipeline. Every product class of finance is represented — equities, credit, funds, rates, macro, commodities, real estate, FX, insurance and digital assets — each given a fixed share of the target, with the measured fill against that budget shown below so any class that is behind is visible rather than implied.

DISCLAIMER.md. The Data is published for informational and research purposes only. It is not investment, financial, legal, tax or accounting advice, is not an offer or solicitation, and is not a system of record or a compliance product. It is assembled by automated agents with no per-record human review, may be incomplete, restated or miscoded, and must be independently verified before you rely on it. No warranty is given; liability is limited. Every figure on this page and inBENCHMARK.mdmeasures stored bytes or tokens, not quality, completeness or fitness.
All figures are measured by the Hugging Face hub and are reconcilable against the repository pages, so the totals can be verified without trusting this card. Updated 2026-11-06 16:24 UTC.

Training-ready text by class
Measured 2026-11-06 16:14 UTC over 78 of 78 shard(s). Tokens use the one convention these cards share - chars / 4 over the chunked text - so each figure is reconcilable against the shards. A token count is what a training run consumes; the stored bytes above are the
ore, not the metal. Class attribution uses the shard path's first segment, so a tier sharing
a segment with another class is attributed to its dominant class, and a label nobody
classified is reported as unclassified rather than assigned.

How this corpus was assembled
The Dragon Finance Corpus is compiled directly from primary sources and kept current by a continuous ingestion pipeline. Each product class is refreshed independently: new publications are collected, packed into immutable shards and published, and the card you are reading is regenerated from the resulting measurements - so the description and the data it describes cannot drift apart.
1. Source selection
Only official and free-public sources are used: US federal agencies and regulators (SEC/EDGAR, US Treasury, FRED, CFTC, FDIC, CFPB/HMDA, NCUA, BLS, Census, BEA, IRS, DOL, EIA, FEMA, NY Fed, Federal Reserve, Federal Register, OFAC, FHFA, USDA, SBA, Cboe, Chicago Fed), non-US official publishers (ECB, BIS, IMF, World Bank, Eurostat, Bank of England, UK Companies House, GLEIF), and US-regulated venue data whose terms permit redistribution. Where a source requires a key it is a free key; no paid subscription is used anywhere.
Deliberately excluded, and this exclusion is what allows an institution to cite the corpus: licensed
or paywalled market data (consolidated tape, CME historicals, FINRA market data, NYSE and Nasdaq tape),
registration-gated portals, and anything scraped from an aggregator. The authoritative statement of what
is excluded, and the terms governing everything here, is DISCLAIMER.md.
2. Four collection shapes
| shape | how it works | used for |
|---|---|---|
| URL-list mirror | a curated URL set is fetched, packed into shards and published | SEC bulk data sets, BIS, DOL Form 5500, USDA NASS, Census directory trees, EDGAR log files, venue candles |
| Direct ingest | files are collected under data/<source>/, then packed and published |
EDGAR filings, XBRL, HMDA, FDIC, NCUA, CFPB, BLS, Census, FRED, Treasury, CFTC, Nasdaq, FINRA |
| Bulk relay | an unmetered object store is streamed into shards with no intermediate processing | volume sources that need no local processing |
| Per-filer EDGAR | one archive per company (CIK), collected as SEC complete submissions | the largest in-scope source: full filing history for the whole US filer universe |
3. Source terms and access limits
Requests are paced per host, not per collection: every sec.gov host shares a single budget because
SEC's fair-access policy is per client, and other hosts get their own. Requests carry an identifying
User-Agent with a contact address, as SEC requires. A terminal 4xx is treated as a fact and not
retried (a 404 will not heal); 429 and 5xx are retried with backoff, honouring Retry-After. Throughput
is therefore a function of each source's stated limit rather than of our own capacity, which is the
behaviour those terms ask for.
4. Why everything is a shard
The hub caps a directory at 10,000 files and these classes run to millions of objects, so each tree is packed into tar shards sized by bytes (about 1.8 GB). Shard size is an operational choice rather than taste: a shard is the unit of publication, so larger shards mean fewer publications per terabyte and smaller ones mean more. A byte target keeps the unit large enough to be efficient while ensuring a refresh republishes only what actually changed.
Shard names are keyed to content, never to sorted position: one archive per CIK for the EDGAR full tree, a UTC timestamp plus a random token for corpus shards. Positional names are a function of which files happened to be to hand at the time, so two collections can produce the same name for different contents - and that silently replaced a published shard once. Collision-free names are a requirement here, not a convention.
5. The publication record, and how a refresh resumes
Every published shard is recorded once, with its member count, its bytes, its sha256 and the range it covers (first/last URL, or CIK). Two rules make the corpus safe to extend:
- A recorded shard is re-verified against the hub. It is skipped only while the hub still lists it, so a repository that is emptied is refilled rather than believed. (Not hypothetical: a whole product class was once silently empty because the record said "done" while the repository was gone.)
- A shard is recorded only once every member has landed. A missed file is retried until it arrives rather than dropped from the record, so a gap is a delay and never a hole.
Because the record is authoritative and carried forward, resuming is incremental: a restart continues where it stopped and re-publishes nothing that is already stored.
6. Measured, never hand-typed
Every figure on this page, in DETAIL.md and in BENCHMARK.md is read from the hub's own usedStorage
at publication time, so any reader can reconcile it against the repository pages without trusting this
text. Capacity is never inferred from local disk: the hub is the durable copy of the corpus, and the hub
is what is measured.
7. Documents count as data
Central banks, the IMF and statistical agencies publish much of their finance material as PDF. Those
are text-extracted rather than skipped, so the publication corpora are training-ready text rather than
stored bytes nothing can read. It is why the Documents and Global classes exist at all.
8. What is deliberately not here
No model weights, training samples, checkpoints or fine-tuned models - this account publishes data, and
the chunked corpus is the final derived stage. Nothing here is a system of record, a compliance product
or investment advice; see DISCLAIMER.md.
How to use it
Open a shard
Every product repository stores tar shards rather than loose files, because the hub caps a
directory at 10,000 files and these tiers run to millions. A member keeps the source's own filename:
a local-ingest shard holds yield_curve_1994.csv or hmda_2023_CA.csv, a per-filer EDGAR shard holds
0000320193-24-000123.txt, and a mirrored URL is named from its last path-and-query segment, so
fredgraph.csv?id=DEXCAUS arrives as fredgraph.csv_id_DEXCAUS. Listing a shard before extracting it is
always the reliable move:
import tarfile
with tarfile.open("0000.tar") as tf:
print(tf.getnames()[:5]) # inspect before you extract
tf.extractall("out/") # members keep their original paths
To pull a single object without downloading the repository, use the Hub client (no clone, no credential needed for public data):
from huggingface_hub import hf_hub_download
p = hf_hub_download(repo_id="dragonlimited/Dragon-Finance-Equities",
filename="data/edgar_complete/cik-0000019617.tar",
repo_type="dataset")
Find what you want before you download it
Objects are named after their source, so the shard path is the index: data/hmda/…,
fdic/deep/…, kraken/ohlc/…, fomc/…, cik-0000019617.tar. The pipeline/ directory in the
Dragon-Finance-Corpus front
door holds the publication record, and each entry names a shard, its member count and its byte size - so
you can locate a tier and estimate its cost before fetching anything.
Resolving any file back to its source
- In a raw shard: the tar member name, plus the shard's sha256 in the publication record.
- In the chunked corpus:
meta.fileis<shard path>::<member name>, andmeta.sourceis the tier - so every chunk resolves to the archive it came from, and from there to the publication record and the source URL. - For the local-ingest tiers,
pipeline/manifest.jsonl.txtadditionally carries per-file provenance: URL, sha256 and fetch timestamp.
Worked examples
Four shapes cover most of what the corpus is used for. All of them need only the Hub client and the standard library.
One company's whole filing history, as text. Each EDGAR tar is one filer, and every member is a complete submission - the primary document plus every exhibit, with an SGML envelope around inline HTML:
from huggingface_hub import snapshot_download
import tarfile, re
snapshot_download("dragonlimited/Dragon-Finance-Equities", repo_type="dataset",
allow_patterns="data/edgar_complete/cik-0000320193.tar", local_dir="aapl")
with tarfile.open("aapl/data/edgar_complete/cik-0000320193.tar") as tf:
for m in tf.getmembers()[:5]:
print(m.name, m.size) # e.g. 0000320193-24-000123.txt
text = tf.extractfile("0000320193-24-000123.txt").read().decode("utf-8", "ignore")
body = re.sub(r"<[^>]+>", " ", text) # de-mark it yourself, or use the chunked corpus below
A panel from one class. A shard usually holds one file per period, which makes a panel a loop:
from huggingface_hub import hf_hub_download
import pandas as pd, tarfile
p = hf_hub_download("dragonlimited/Dragon-Finance-Rates", repo_type="dataset",
filename="data/treasury/0000.tar")
with tarfile.open(p) as tf: # members: yield_curve_1990.csv, ...
frames = [pd.read_csv(tf.extractfile(m)) for m in tf.getmembers()]
panel = pd.concat(frames, ignore_index=True) # read the header; do not assume column names
Loan-level records by state and year. HMDA members are named hmda_<year>_<state>.csv, so file
selection is a glob rather than a parse:
from huggingface_hub import snapshot_download
import pandas as pd, tarfile, glob
snapshot_download("dragonlimited/Dragon-Finance-Credit", repo_type="dataset",
allow_patterns="data/hmda/*.tar", local_dir="hmda")
rows = []
for shard in glob.glob("hmda/data/hmda/*.tar"):
with tarfile.open(shard) as tf:
for m in tf.getmembers():
if m.name.startswith("hmda_2023_"): # one year across every state
rows.append(pd.read_csv(tf.extractfile(m)))
Training text, without downloading the raw shards. This is what the chunked corpus exists for: one JSON object per line, 512-token windows with 64 tokens of overlap, each carrying its provenance.
from huggingface_hub import hf_hub_download
import json
p = hf_hub_download("dragonlimited/Dragon-Finance-Corpus", repo_type="dataset",
filename="corpus/chunks-20261104T174041Z-07cdc4.jsonl") # any shard of the set
with open(p) as fh:
for line in fh:
rec = json.loads(line)
if rec["meta"]["source"] == "fomc": # e.g. every FOMC document, already extracted
print(rec["meta"]["file"], rec["meta"]["tokens"], rec["text"][:80])
The shard list changes as the corpus grows, so take the names from corpus/ rather than hardcoding one;
corpus/README.md documents the schema and the current source mix.
Caveats that matter when you analyse it
- Mixed vintages. Filings are amended and series are revised; the corpus holds what the source published and is not a point-in-time snapshot. Keep an as-of date in any analysis.
- Automated assembly, no per-record human review. Ingestion, parsing and any enrichment are mechanical and can be wrong. Numeric and tabular material dominates the raw store relative to prose; check the per-class token figures before assuming text volume.
- Attribution and licences travel with each source. FRED is CC-BY-4.0 (attribution required), SEC EDGAR is US public record (identifying User-Agent and fair-access limits required), HMDA carries FFIEC/CFPB terms, exchange data carries venue terms. You are responsible for complying with the source terms before any redistribution.
- Not a system of record. Verify before you rely on it. See
DISCLAIMER.mdfor the full terms, including the limits of liability.

Each product repository stores tar shards rather than loose files — the hub caps a directory at 10,000 files and these tiers run to millions. Members keep their original names and paths.

Text is extracted from PDFs as well as tables (pdf_text, page-capped), because a large part
of central-bank, IMF and statistical-release finance material is published as PDF - so the document
corpora are training-ready text rather than stored bytes nothing can read.
No model weights, training samples or checkpoints are produced or published here. The chunked corpus is the final derived stage; nothing downstream of it exists on this account.
How the chunked corpus is made
The raw shards above are the ore; corpus/chunks-*.jsonl in the front door is the metal. It is built
one shard at a time: each tar is downloaded, read member by member and deleted
again, so one shard is held at a time.
- Text extraction, per format. PDFs are text-extracted (page-capped), because a large part of
central-bank, IMF and statistical-release finance material is published as PDF. HTML and SGML - which
includes EDGAR's complete submissions, an SGML envelope around inline HTML - is de-marked. Archives
inside a shard (
.zip,.gz) are opened and read inside, with an entry budget per shard. - Chunks are token-accurate. Windows are 512 tokens with 64 tokens of overlap, measured with a real tokenizer - used purely as a ruler, so that "a 512-token chunk" means the same thing to every consumer.
- Ceilings keep the corpus readable. A per-document cap stops one pathological file dominating, a per-tier cap stops one tier dominating, and the numeric tiers (futures tables, venue candles) get a much smaller cap so kilobytes of number grids cannot swamp prose. Truncation is recorded in the publication record, never silent.
- Output is sharded, not one file. The hub has no delta upload, so a single growing file would be re-pushed in full every round. Shards roll at a fixed size and are published one at a time; the shard still being written is published from a frozen snapshot, so an upload never reads a file that is growing underneath it.
- Resumable. A shard read in full is recorded, so a resumed run continues rather than restarting.
The full procedure - every extraction rule, every cap, the exact record schema and how to consume the
chunks - is in corpus/README.md.
Integrity
Every shard records its sha256, its member count and the source key range it covers. Shards are append-only, so extending the corpus adds new shards rather than rewriting existing ones and a resumed collection re-publishes only what changed. A shard whose member is missing is never recorded as complete, so a missed file is retried rather than dropped.
Reproduce
Sources are public and keyless; reproducing or extending the corpus needs only bandwidth and disk.
