The Coherence-Based Genealogical Method, for the manuscripts you edit
Koinonia is a web workbench for the Coherence-Based Genealogical Method (CBGM) of New Testament textual criticism. It takes a tradition from manuscript transcriptions to local stemmata, textual flow and a global stemma, with the evidence, the editors' judgements and every change kept together.
Upload a TEI collation, or transcriptions of single manuscripts that Koinonia collates for you. Edit each passage's local stemma, and Koinonia works out the genealogy, fast enough for a book the size of Acts.
From transcriptions to a global stemma
- Transcribe. Upload IGNTP-style TEI transcriptions of single manuscripts. A second, independent transcription can be reconciled verse by verse, then proofread and approved.
- Collate. Koinonia collates the transcriptions against a base witness and gives every variation unit a provisional local stemma. Or upload a TEI collation directly.
- Judge. Edit the local stemma of each passage, split and merge readings, and correct the collation. Every edit records who, when and why.
- Compute. Pregenealogical and genealogical coherence, potential ancestors, optimal substemmata, the three textual flow diagrams and the global stemma.
- Publish. TEI headers with editorial declarations and identifiers, versioned files, and a package ready to deposit on Zenodo for a DOI.
Tools for editors
Textual flow
See how each reading was passed on: the complete flow, one reading's attestation, or only the changes of reading.
Categories of change
Tag changes in local stemmata, follow a scribal tendency through the tradition, and test how far the stemma rests on those judgements.
Witness profiles and groups
Each witness's agreement with every other, three distance measures, clustering, heatmaps and multidimensional scaling.
Page images as evidence
Upload page images, mark the regions that are the evidence for a passage, and record how sure each reading is.
Readings in English
Every reading glossed word by word, with seven Greek lexicons to compare. Optional AI support, off by default.
Shared projects
Share a project with viewers or editors, collect error reports, and download backups.
