# Selecting rows

Every table in this repository is Parquet. One row of `data/<source>/<batch>/part-*.parquet` is one downloadable item: a file, an archive member, a WARC record, a byte range or an API response. The tables under `meta/` are small and say which rows are worth using.

A batch still being collected also has `data/<source>/<batch>/part-tail.parquet`: the rows that do not yet fill a numbered part file. It is replaced as collection goes on and its rows move into the next `part-<number>.parquet` once that file fills, so for tail rows `row_file` and `row_index` are not stable. Globs such as `part-*.parquet` or `*/*.parquet` include it. A finished batch has no tail file: all of its rows are in numbered part files.

## Row fields

| Field | Meaning |
|---|---|
| `source` | Source name (see meta/sources.json). |
| `batch` | Batch inside the source (one snapshot or collection run). |
| `collection` | Collection name inside the source. |
| `ext` | File extension without the dot, as found at the source. |
| `uri` | Address to download from (HTTPS where the source offers it). |
| `range_offset, range_length` | Byte range inside the file at uri, for records stored inside a larger file. |
| `member_path, parent_pointer_id` | Path of a member inside an archive, and the archive's pointer. |
| `zip_local_header_offset, zip_compression_method, zip_compressed_size` | Where a zip member's bytes sit, so it can be read with range requests. |
| `size_bytes` | Size of the item in bytes (empty when the source does not say). |
| `media_type` | Media type when the source states one. |
| `sha256, sha1, md5, crc32` | Hashes as raw bytes; use lower(hex(sha256)) for the hex form. |
| `origin_url, origin_time` | The page the item was found on and when it was captured. |
| `truncated` | Why stored content was cut short (empty when it was not). |
| `license_spdx, license_training_ok, license_redistribution_ok, license_notes` | The row's own license when it differs from the batch license. |
| `extra` | Anything else the full pointer carries, as JSON; fetch.py rebuilds the full pointer from it. |
| `row_file, row_index` | Where the row sits: the data file (source/batch/part file) and the row number in it, counting from 0. Not stored in the data files; tools/fetch.py adds them when reading, the starter files carry them. meta/duplicates.parquet names rows by them. |

## Tables under meta/

- `meta/batches.parquet`: one row per source and batch: license tiers (training_ok, redistribution_ok), reachability from the last link check, the overall size cap used by tools/fetch.py (max_size_bytes), content categories, and the constants and rules used to rebuild full pointers.
- `meta/duplicates.parquet`: rows the default filter removes as duplicates, each named by its place in the data files (batch, row_file, row_index), with the reason and the copy that is kept (keep_*): natural_key, another row with the same source, uri, range_offset and member_path was kept (the one from the latest batch; within one batch the first in file order), and that kept row has natural_key_conflict true in tools/fetch.py output; superseded, the row belongs to a snapshot replaced by a newer batch (keep_batch); same_sha256, same_sha1, same_md5, another row with the same hash was kept.
- `meta/bench_overlap.parquet`: rows found in public benchmark tasks: scope row matches one row, scope container matches a whole collection; hit_class says how the match was made. When one row is a copy of benchmark data (benchmark_copy), its whole collection is listed only if the collection is one self-contained unit: one package, code repository, dataset or model repository (collection_kind "unit" in meta/sources.json, except the collections named in bucket_collections). Where collections are buckets (by file type, crawl, date, site and the like), only that row is listed. Only rows of files that were compared with the benchmark list can be found here (see meta/bench_checked.parquet).
- `meta/bench_checked.parquet`: which rows were compared with the benchmark list. It lists only what was checked: scope file has one row per data file (row_file) every pointer file behind which was scanned (reason scanned); the tail file of a batch still being collected is never listed, since it is replaced as collection goes on. Scope container lists collections whose name matches a benchmark and that await a ruling (reason pending_ruling). The one row with scope unlisted (reason not_listed) applies to every data file not listed here: files not compared yet and files published after this table was built. default_keep says whether the default filter keeps the rows.
- `meta/tags.parquet`: use tags (for example data-processing or help-requests) for each source, batch, collection, extension, metadata value and content category, with row counts and the reference size cap of the tag's content class (max_size_bytes).
- `meta/size_caps.json`: reference size caps: for each content class the typical size of benchmark task files of that class, and the overall cap over all benchmark task files; how each was derived (sample count, percentile, value) and how it is recalibrated; provisional. They do not remove rows: tools/fetch.py uses the overall cap when downloading, or the class caps with --cap per-class.
- `meta/sources.json`: per-source details, including the layout used to rebuild full pointers.
- `meta/coverage.json`: totals by license tier, source, unit, size and tag.

`starter/<tag>.parquet` holds a sample of about ten thousand rows per tag that pass the default filter, spread over sources (at most 30% from one source), extensions and size classes.

`cards/<source>.yaml` is a source card: what the files of one source are (types, structure, what a task could be built from, risks), how a sample was drawn and read, and for every field `evidence.<field>.fill`: auto (computed from the index, refreshed daily), judgment (from sample files that were downloaded and read, with the basis and the files used), derived (a fixed rule over other fields) or unfilled (no evidence yet). Read the evidence before relying on a field; ratios count the sample, not the whole source.

## The default filter

The default subset only contains rows of data files that were compared with the benchmark list (AA-Briefcase-Lite, APEX-Agents, Agents' Last Exam, AndroidWorld, AutomationBench, BrowseComp, BrowseComp-Plus, CyberGym, DeepSWE, EnterpriseOps-Gym, Finance Agent, FrontierSWE v2, GDPval, Harvey LAB, MCP Atlas, MCPMark, Multi-SWE-bench, NL2Repo, OSWorld, OSWorld 2, SWE-bench Multilingual, SWE-bench Multimodal, SWE-bench Pro, SWE-bench Verified, SciCode, Terminal-Bench, Toolathlon, WideSearch, tau2-bench), as of 2026-10-05T14:11:22+0800, minus the copies of benchmark data found there and duplicate copies of the same file. Rows of files that were not compared, of the tail file of a batch still being collected, of files published after meta/bench_checked.parquet was built and of collections awaiting a ruling are left out; meta/bench_checked.parquet lists the data files that were compared and the collections awaiting a ruling, and any file it does not list counts as not compared. License tiers, sizes and versions do not remove rows; the queries below choose by them. Truncated rows, empty files and rows of batches whose link check was partial stay in; the reference counts below count them. A row passes when all of these hold:

- `not_duplicate`: the row is not listed in meta/duplicates.parquet (one copy of each duplicated file is kept; of rows that share a natural key only the latest is kept).
- `not_in_benchmark_row / not_in_benchmark_container`: the row and its collection are not in meta/bench_overlap.parquet with hit class benchmark_copy, task_file, data_address (copies of benchmark data found in the rows that were compared, including collections derived from a benchmark).
- `checked_for_benchmarks`: the row's data file is listed in meta/bench_checked.parquet as compared with the benchmark list (checked true), and its collection is not listed there as awaiting a ruling; rows of files not listed there (not compared yet, or published after that table was built) do not pass.

`tools/fetch.py` applies it unless you pass `--no-default-filter`. Size caps apply only when downloading: by default the overall cap of meta/size_caps.json (the 99th percentile of all benchmark task files) guards against huge files; `--cap per-class` uses the reference cap of the row's content class and `--max-size N` uses N bytes. A row above its cap is recorded as too_large and not downloaded; a row of unknown size is downloaded up to the cap.

## Rows per source

Every row of the index is counted once: either it is in the default subset or it is removed by the first rule of the default filter it fails (duplicate copies first, then copies of benchmark data, then rows that were not compared with the benchmark list). Rows equals Default subset plus In a benchmark plus Duplicate copy plus Not checked.

## Querying with DuckDB

Run these statements once (DuckDB 1.1 or newer reads `hf://` paths; set `HF_TOKEN` for higher rate limits). They define the views used below: `p` rows, `b` batches, `d` duplicates, `o` benchmark overlap, `c` benchmark check coverage, `t` tags.

```sql
CREATE OR REPLACE VIEW p AS SELECT * EXCLUDE (filename, file_row_number), regexp_extract(replace(filename, '\', '/'), '[^/]+/[^/]+/[^/]+$') AS row_file, file_row_number AS row_index FROM read_parquet('hf://datasets/Battam/agentic-env-index/data/*/*/*.parquet', union_by_name = true, filename = true, file_row_number = true);
CREATE OR REPLACE VIEW b AS SELECT * FROM read_parquet('hf://datasets/Battam/agentic-env-index/meta/batches.parquet');

```

The query reads the row tables remotely and only the columns it needs; a full pass over every source moves a few gigabytes. Add `p.source IN (...)` or read `data/<source>/*/*.parquet` to stay small. The view adds training_tier and redistribution_tier (yes, conditional, no or unknown) and class_cap_bytes (the reference size cap of the row's content class) and natural_key_conflict (true when other rows with the same natural key were removed as duplicates and this one, from the latest batch, was kept) and checked_for_benchmarks (true when the row was compared with the benchmark list and its collection is not awaiting a ruling).

## Ready-made queries

Each query runs on the `selected` view above.

1. Only rows that may be used for training (training tier yes or conditional):

```sql
SELECT p.source, p.uri, p.size_bytes, p.training_tier FROM selected p
WHERE p.training_tier IN ('yes', 'conditional') LIMIT 20;
```

   `python tools/fetch.py --tier yes,conditional --limit 20 --dry-run`

2. Only the latest version of each package. Latest means the version released last (by release time, so a fix released later for an older line counts as the latest); all files of that version are kept, and rows without a version or a release time are left out. Package ecosystems and the release time used:

| Source | Release time |
|---|---|
| pypi | `source_meta.upload_time` |
| npm | `source_meta.published` |
| crates-io | `source_meta.created_at` |
| cran | none (the snapshot lists only the current version of each package) |
| conda-forge-packages | `source_meta.timestamp` |
| ansible-galaxy-collections | `source_meta.published` |
| artifact-hub-helm-charts | `source_meta.created` |
| go-module-proxy-zips | `source_meta.index_timestamp` |
| hackage-packages | `source_meta.uploaded` |

   Not ordered by this query:

- debian-sources: rows carry no release time, and Debian versions need the dpkg ordering rules, which plain SQL does not have; each suite lists one version per source package, so choose a suite with `source_meta.suite` instead.
- nuget, rubygems: no release-time field is defined for these rows yet; every version is kept.

```sql
CREATE OR REPLACE VIEW latest_version AS

3. Only rows within the reference size cap of their content class (rows of unknown size stay in; `tools/fetch.py --cap per-class` stops their download at the same cap):

```sql
SELECT p.source, p.uri, p.size_bytes, p.class_cap_bytes FROM selected p
WHERE p.size_bytes IS NULL OR p.size_bytes <= p.class_cap_bytes LIMIT 20;
```

   `python tools/fetch.py --cap per-class --limit 20 --out ./files` (rows above the class cap are recorded as too_large and not downloaded)

## Examples

1. Rows tagged `data-processing`, CSV files only:

```sql
SELECT p.source, p.uri, p.size_bytes FROM selected p JOIN b ON b.source = p.source AND b.batch = p.batch WHERE lower(p.ext) = 'csv' AND EXISTS (SELECT 1 FROM t WHERE t.source = p.source AND t.batch = p.batch AND t.collection IS NOT DISTINCT FROM p.collection AND t.ext IS NOT DISTINCT FROM p.ext AND t.meta_value IS NOT DISTINCT FROM (CASE WHEN b.meta_key IS NOT NULL THEN (CASE WHEN starts_with(coalesce(p.extra, ''), '{"_row":') THEN json_extract_string(p.extra, '$._row.source_meta.' || b.meta_key) WHEN json_type(p.extra, '$.source_meta') IS NOT NULL THEN json_extract_string(p.extra, '$.source_meta.' || b.meta_key) WHEN NOT coalesce(json_contains(json_extract(p.extra, '$._absent'), '"source_meta"'), false) THEN json_extract_string(b.const_source_meta, '$.' || b.meta_key) END) END) AND t.content IS NOT DISTINCT FROM CAST((CASE WHEN starts_with(coalesce(p.extra, ''), '{"_row":') THEN json_extract(p.extra, '$._row.content') WHEN json_type(p.extra, '$.content') IS NOT NULL THEN json_extract(p.extra, '$.content') WHEN NOT coalesce(json_contains(json_extract(p.extra, '$._absent'), '"content"'), false) THEN b.const_content END) AS VARCHAR) AND t.tag IN ('data-processing')) LIMIT 20;
```

   `python tools/fetch.py --tag data-processing --ext csv --limit 20 --out ./files`

2. Rows tagged `office-spreadsheets`, smallest first:

```sql
SELECT p.source, p.uri, p.size_bytes FROM selected p JOIN b ON b.source = p.source AND b.batch = p.batch WHERE EXISTS (SELECT 1 FROM t WHERE t.source = p.source AND t.batch = p.batch AND t.collection IS NOT DISTINCT FROM p.collection AND t.ext IS NOT DISTINCT FROM p.ext AND t.meta_value IS NOT DISTINCT FROM (CASE WHEN b.meta_key IS NOT NULL THEN (CASE WHEN starts_with(coalesce(p.extra, ''), '{"_row":') THEN json_extract_string(p.extra, '$._row.source_meta.' || b.meta_key) WHEN json_type(p.extra, '$.source_meta') IS NOT NULL THEN json_extract_string(p.extra, '$.source_meta.' || b.meta_key) WHEN NOT coalesce(json_contains(json_extract(p.extra, '$._absent'), '"source_meta"'), false) THEN json_extract_string(b.const_source_meta, '$.' || b.meta_key) END) END) AND t.content IS NOT DISTINCT FROM CAST((CASE WHEN starts_with(coalesce(p.extra, ''), '{"_row":') THEN json_extract(p.extra, '$._row.content') WHEN json_type(p.extra, '$.content') IS NOT NULL THEN json_extract(p.extra, '$.content') WHEN NOT coalesce(json_contains(json_extract(p.extra, '$._absent'), '"content"'), false) THEN b.const_content END) AS VARCHAR) AND t.tag IN ('office-spreadsheets')) ORDER BY p.size_bytes LIMIT 20;
```

   `python tools/fetch.py --tag office-spreadsheets --limit 20 --dry-run`

3. Rows tagged `sysadmin-devops`, from the starter sample:

```sql
SELECT source, ext, count(*) FROM read_parquet('hf://datasets/Battam/agentic-env-index/starter/sysadmin-devops.parquet') GROUP BY ALL ORDER BY 3 DESC;
```

   `python tools/fetch.py --starter sysadmin-devops --out ./starter`

`python tools/fetch.py --print-sql ...` prints the exact query the script runs, so any selection can be repeated in DuckDB. The script checks size and every hash of each download and writes `fetch_manifest.jsonl` with one line per selected row. With `--check-content` it also flags downloads that are hard to use (scanned PDFs, error pages saved as files, extensions that do not match the content) in the manifest field `content_check`; this needs the `file` command and poppler-utils, and a check whose tool is missing is skipped and named there.
