Data Collection, Derivation, and Translation Process

• Get data from sources cited
• Input raw data into sheets of ODS files
• Additional sheets created in ODS file with formulae to derive statistics
• Notes added to ODS files to clarify dates and versions when (seemingly) out of order or skipping versions
• Export from ODS sheets to separate CSV files
• Use custom converter.js (Node.js) program to convert CSV files into JSON, YAML and Markdown files

Notes

• Statistics do not include trivial values (e.g. 0 days since last update of a major version on the day of the major version's release).
