The manuspec specification
This specification states exactly what each manuspec file holds and how every value in it is computed. The schemas, SQL, JSON-LD context, registries, vectors and fixtures are normative too, and each chapter says which of them it relies on. A chapter and a vector that disagree signal a bug, so please report it in the repository, https://git.scient.ing/infra/manuspec.
Two readers will get the most from it: implementers who build a reader, writer, converter or checker, and experts who want the precise rules. Newcomers should start with the guides, which explain what the formats are for. This text assumes you know why and tells you how.
Reading paths
Find the row for the job you are doing and read its chapters after those in the first row. Chapter numbers are those in the table below.
| If you are writing | Read |
|---|---|
| Anything at all | 0, 1, 3, 4 and 5: introduction, conventions, nodes, identity and the content values. |
| A reader of packages | Then 2, 6, 7 and 12: the model, anchors, geometry and the package. |
| A converter | Then 9, 10 and 11: figures and tables, references, and corrections with the gate. |
| A store or a server | Then 8, 13 and 14: receipts, the database form, and rights. |
| A writer or reader of annotation, teaching or data files | Then 15 to 21. |
| A validator | Chapter 22, with registry/rules.json. |
