# Springtail Wiki open data

Release 76b1850c12464746. Data reviewed up to 2026-10-23.

This is the data behind [Springtail Wiki](https://springtails.wiki/), as tables and as full records. It holds the species, the hobby cultures, the trade names, the taxa, the sources and the claims. Every claim has an evidence level and its sources, and the tables keep that link.

The works that the claims cite have their own rights. The tables hold facts about them, such as the title and the year, and not their text.

## Files

| File | What it holds | Rows |
| --- | --- | --- |
| `species.csv` | Species. One row for each species page. Hobby cultures are in cultures.csv, and the claims behind each value are in species_claims.csv. | 47 |
| `species_claims.csv` | Claims behind each species value. One row for each claim that a part of a species record rests on. Join it to species.csv by species_id and to claims.csv by claim_id. | 817 |
| `life_tables.csv` | Life history at several temperatures. One row for each temperature at which a species was measured. The claims behind the table are in species_claims.csv under husbandry.lifeTable. | 3 |
| `cultures.csv` | Hobby cultures. One row for each hobby culture. A culture is a line of animals under a hobby name. It is placed under a species page with a stated confidence, and the name does not make it a species. | 53 |
| `trade_names.csv` | Trade names. One row for each name a label or a listing might use. The species a name might mean are in trade_name_candidates.csv. | 56 |
| `trade_name_candidates.csv` | What a trade name might mean. One row for each species or taxon a trade name might stand for, with how likely that is. Exactly one of species and taxon is filled. | 92 |
| `taxa.csv` | Taxa above species. One row for each node of the classification above species. A taxon is a concept under a named classification, not a timeless fact. | 126 |
| `sources.csv` | Sources. One row for each work the statements cite. The standing says how far the entry has been checked against a registry or a stored copy. | 83 |
| `claims.csv` | Claims. One row for each statement on the site. Every claim names its subject, its evidence level and its sources, which are in claim_sources.csv. The text has no markup. | 1132 |
| `claim_sources.csv` | Sources behind each claim. One row for each source a claim cites, in the order the claim gives them, with the place in the source. | 1360 |
| `questions.csv` | Open questions. One row for each thing that science or the hobby does not yet know, with what would help. | 43 |
| `species.json` | Species, in full. Every field of every species record except the drawing parameters. Foods, bands, life tables, character states and the claims behind them stay nested as they are authored. | 47 |
| `cultures.json` | Hobby cultures, in full. Every field of every culture record except the import notes, which belong to the spreadsheet the first list of cultures came from and say how a page was to be made. | 53 |
| `trade_names.json` | Trade names, in full. Every trade name with its candidates, the characters that tell them apart and its local names by language. | 56 |
| `taxa.json` | Taxa, in full. Every taxon with its character states, the names that have been used for it and its history. | 126 |
| `sources.json` | Sources, in full. Every source with its standing and the result of the last check. | 83 |
| `claims.json` | Claims, in full. Every claim with its subject, its three reading levels, its evidence level and its sources with the place in each. | 1132 |
| `questions.json` | Open questions, in full. Every open question with the phrasings readers use when they ask it. | 43 |
| `characters.json` | Characters and their states. The features the identification key reads, with the states each can take. The character states in species.json and taxa.json name these. | 13 |
| `datapackage.json` | The description of the tables in the Frictionless Data Package format, with every column, its type and the links between tables. | |
| `manifest.json` | The name, size and SHA-256 checksum of every file in the release. | |

The CSV files are UTF-8, with a header row, commas between cells, double quotes around a cell that needs them and a line feed at the end of every line. Open them in a spreadsheet with the import dialog and choose UTF-8, so that names with accents read correctly.

## How to read the data

- Every row has an identifier. The same identifier means the same thing in every table. A species with the identifier `folsomia-candida` has its page at https://springtails.wiki/species/folsomia-candida/.
- An empty cell means that no value is recorded. It does not mean zero, and it does not mean no.
- A cell that holds a list separates the items with a semicolon, and an item never contains one. A text column is not a list, so a semicolon in it is part of the text.
- Dates are written year, month, day. Lengths are in millimetres, temperatures in degrees Celsius, humidity in percent and times in days. A column that holds a quantity says its unit in its description, and most end their name with it, as `_mm`, `_c`, `_pct` and `_days` do.
- The text has no markup. On the site, italics, units and links are marked inside the text. Here an italic name is plain, a temperature is in degrees Celsius and a link is replaced by the words it names.
- A hobby name is not a species. A hobby culture is a line of animals under a name. It is placed under a species page with a qualifier and a confidence. Read both before you treat the placement as a fact.
- The values say what the sources say, and the evidence level says how well they say it. Many keeping values rest on the experience of keepers and sellers and not on experiments. Choose the evidence levels you trust before you use a number.

### Evidence levels

Every claim has one of these.

- `peer-reviewed`. Reported in the published scientific literature.
- `expert-source`. From a specialist checklist, official guideline or named expert.
- `hobby-consensus`. Two or more independent keepers or sellers agree.
- `anecdotal`. One keeper or seller reports it. Treat it as a lead.
- `unknown`. Nobody has tested this yet. The open question is linked.

A claim with `verification` set to `unchecked` has a source and a place in it, but a person has not yet compared the statement with that place. Treat it as a draft and read the source if the statement matters.

## Versions

A release has an identifier taken from the content of its files, so the same data always has the same identifier. A release at https://springtails.wiki/data/v/76b1850c12464746/ never changes. https://springtails.wiki/data/latest/ always holds the newest release, and https://springtails.wiki/data/index.json lists the releases. Cite the identifier and not the word latest.

## Corrections

If you find a mistake or know a source we missed, send it at https://springtails.wiki/contribute/. Changes to the data are listed at https://springtails.wiki/changelog/.
