Appendix A — JSON Schema

Contents of FBL 0.9

The normative schema is fbl.schema.json beside this document (JSON Schema draft 2020-12, $id https://etalii.net/adp/fbl/schema/0.1/fbl.schema.json). Its $defs are: Document, Binding, Claims, Marker, Body, Family, FileRule, PluginReader, TextDefaults, Header, BlockRule, (FBL 0.7) SectionRule, ElementRule, RelationRule, IdBinding, Slot, (FBL 0.9) GrammarSource and Recover, AttributeBinding, Insert, Remove, RegistrationSettings, Template, Registration, Splice, Fixture, Edit, the model changes ModelChange and ChangePosition (FBL 0.2, section 11.2), and the helpers Name, BindingRef, Regex, Selector. While FBL is a draft, the schema keeps its 0.1 $id and accepts every version from "fbl": "0.1" to "0.9". It references DISL's Doc, LocalizedText, Expression and TypeRef.
