For everything the source does not say.

A research database where uncertainty is a field, not a compromise.

The problem

Every database eventually forces you into a statement you cannot evidence. A date field wants a day. A place field wants a place. The footnote that qualifies it ends up in your head — not in your data.

What Evidoxa does differently

Certainty

Four levels, not one assertion.

Certain, probable, possible, unknown — per field, not per record.

  • Certain
  • Probable
  • Possible
  • Unknown

Dating

A year without a month is a complete answer.

Year, month and day are stored separately. What you do not know, you need not invent.

Certainty of the date

Evidence

Every claim points at its source.

Evidence attaches to the individual field — with page reference, quotation and diplomatic transcription.

Relations

Anything can connect to anything.

You define the relation types. Every relation carries its own certainty.

Where this stands

Evidoxa is built against dissertations, not personas.

What gets built next is decided by the historians doing the work.
