This repository contains an open source collection of historical text genealogies, in forms of tree-like graphs (stemma) for a variety of languages.
Find more information on the project website.
You can contribute by sending us images and/or metadata and DOT files,
- by making a pull request on the main branch (preferred);
- by opening an issue;
- by sending it to us via email, to OpenStemmata [at] protonmail.com.
If you wish to contribute, have a look at the examples folder:
It contains several cases:
- a simple case, but with very complete metadata: Segre_1971_Roland
- a slightly more complex case: Paris_1872_Alexis
You can also read our more detailed Guidelines !
Actual data is stored in the data folder, and are sorted by linguistic code (e.g., fro for Old French traditions; gmh for Middle High German).
Each record is contained in a dedicated folder, and can contain up to three elements:
stemma.png: scan from the source edition;metadata.txt: metadata file about the stemmastemma.gv: GraphViz DOT format file for the stemma.
The following resources can help you create the necessary files:
- Our form metadata creator: just fill up the form and get the txt content.
- Edotor: a free online DOT editor with graphical view.
DOT format is quite easy to master, and uses the following patterns:
a -> blink from a to ba -> b [style="dashed"]dashed link from a to b (contamination)a -> b [style="dashed"]grey link from a to b (uncertainty)alpha[color="grey", label="α"]color alpha in grey (for hypothetical nodes, i.e., not extant manuscripts) and label it properly.
If you're hesitant, head over to the online editor for creating the file !
