# Deutsches Textarchiv (DTA) Documents

This datasets hosts all documents from the Deutsches Textarchiv (DTA).

One row per work of the [Deutsches Textarchiv (DTA)](https://www.deutschestextarchiv.de/), built from the
official DTA dump `dta_komplett_2026-02-10` (TCF format). The dataset contains **5,480 documents** spanning
**1472 to 1987** with about **205M tokens** and **1.4B characters** of German text, with two text views per document:

* `text`: the historical, layout-faithful transcription (line breaks, long s `ſ`, combining diacritics, original spelling);
* `text_normalized`: the same text in modern orthography, produced by applying the DTA CAB orthography corrections
  (`operation="replace"`) to the token layer.

Rich bibliographic metadata comes directly from the embedded TEI header: authors with GND identifiers, original
publication date and place, publisher, holding library and shelfmark, typeface, four genre schemes, DTA subcorpus
labels and the per-work license. Licenses vary across the corpus, so please check the `license_family` column
before reuse (see [Licensing](#licensing)).

## Dataset structure

### Configs and splits

| Config | Split | Rows | Files |
|---|---|---:|---|
| `documents` (default) | `train` | 5,480 | `documents/train-0000[0-5].parquet` (6 shards, zstd-compressed Parquet) |

There is only one split, because the dataset is a corpus and not a benchmark.

### Loading

```python
from datasets import load_dataset

ds = load_dataset("histde/dta-documents", "documents", split="train")
print(ds[0]["title"], ds[0]["year"])

# Only permissively licensed works, as a streaming iterator
permissive = load_dataset("histde/dta-documents", "documents", split="train", streaming=True)
permissive = permissive.filter(lambda d: d["license_family"] in {"cc0-1.0", "cc-by-4.0", "cc-by-3.0"})
```

With Polars, straight from the Parquet shards:

```python
import polars as pl

df = pl.read_parquet("hf://datasets/histde/dta-documents/documents/train-*.parquet")
df.filter(pl.col("year") < 1700).select("id", "title", "license_family", "num_tokens")
```

## Dataset creation

### Source data

The DTA is a reference corpus of printed German from the late 15th to the early 20th century, curated by the
Berlin-Brandenburg Academy of Sciences and Humanities (BBAW). Texts were transcribed by double keying from
first editions wherever possible, and are published with TEI headers, sentence and token layers and
orthographic normalization from the CAB tool chain.

This dataset was built from the complete TCF dump `dta_komplett_2026-02-10`, which comes in two variants:

* `simple/` (5,107 files): CMDI metadata and the layout-faithful historical text (`<text>` layer);
* `full/` (5,471 files): CMDI metadata and the annotation layers (tokens, sentences, orthography).

The union of both variants gives 5,481 works. One work (`ford_pitty_1633`) is excluded because its TCF file is
not well-formed XML.

### Processing

* `text` comes from `simple/` where available (`text_source = "layout"`, 5,105 docs). For the 375 works only
  present in `full/`, it is reconstructed by space-joining the token layer (`text_source = "tokens"`), so
  line breaks and the original whitespace are lost there.
* `text_normalized` is the `full/` token layer with CAB `replace` corrections applied (multi-token corrections
  replace the whole span), space-joined. It is null for the 10 works only present in `simple/`.
* Metadata is deliberately kept un-flattened: authors are a list of structs, all four genre schemes are
  separate columns, the raw license URL is kept next to a normalized `license_family`.
* `num_tokens`, `num_types`, `num_characters`, `num_images` and `num_pages` are the extent measures from the
  DTA header, not recomputed values.

The conversion script and the statistics script are available in the
[dta-experiments](https://github.com/histde/dta-experiments) repository.

## Licensing

The DTA publishes every work under its own license, and this dataset keeps that information per row in the
`license` (raw URL from the header) and `license_family` (normalized) columns. There is **no single license**
for the whole dataset. Note that only `cc0-1.0` is a public domain dedication; all `cc-by-*` licenses carry
binding conditions (attribution, share-alike, or non-commercial use), and about 28% of the documents are
restricted to non-commercial use (`cc-by-nc-3.0`, `cc-by-nc-sa-4.0`, `noc-nc-1.0`, `out-of-copyright-nc`).

To select a subset that fits your use case:

```python
ds_sa = ds.filter(lambda d: d["license_family"] in {"cc0-1.0", "cc-by-4.0", "cc-by-3.0", "cc-by-sa-4.0", "cc-by-sa-3.0", "cc-by-sa-2.0"})
```

## Considerations for using the data

* **Coverage is uneven.** Roughly 60% of the tokens date from 1750 to 1899; the 15th and 16th centuries are
  thinly covered. Newspapers (`Zeitung`) dominate the document count but make up only 8% of the tokens, and
  a single project (Alexander von Humboldt's writings) contributes 183 short documents.
* **Historical content.** The texts reflect the views, language and stereotypes of their time, including
  religious, political and colonial-era writing. They are provided for research on historical German and
  should not be taken as statements of fact or acceptable opinion.
* **Normalization is automatic.** `text_normalized` comes from the CAB tool chain and is not manually
  corrected. Expect residual errors, especially for very early texts, Latin passages, and proper names. The
  normalized text is also whitespace-tokenized (punctuation is separated by spaces), whereas `text` keeps the
  original layout.
* **`text` is not uniform.** 375 documents have their historical text reconstructed from the token layer and
  lack line breaks; check `text_source` if layout matters to you.
* **Metadata quirks.** Genre fields are null for a large share of the works in the DTA scheme (use the DWDS
  scheme for complete main-genre coverage), typeface strings contain a few typos, and `year` is parsed
  heuristically from the free-text `date_published`.
