Module schema 

Database schema.

Structs

StoreOptions

Options chosen when a store is created.

Constants

SCHEMA_VERSION

Current schema version stored in oxilite_meta. Version 2 keeps the schema registry as RDF in <oxilite:schema> (no schema_graphs table) and scopes tbox_closure; opening a version 1 store migrates it (ops::open_job).

TBOX_INDEX

TBOX_TABLE

The TBox closure cache, one closure per scope (see reason::closure_statements).

Functions

base_schema

DDL statements creating (idempotently) the oxilite schema without versioning.

create_schema

DDL creating the oxilite schema, versioning included: a script for a new database (a D1 migration). Not idempotent when versioning is on (ALTER TABLE); stores opened in place use base_schema and apply their level through version::change_statements.

schema_sql

The schema as one SQL script (for wrangler d1 migrations).

schema_sql_with

The schema plus extra DDL of optional modules (e.g. oxilite-jsonld’s tables).

system_graph_statements

Statements writing the system graphs (see StoreOptions::system_graphs) and rebuilding the schema caches they scope.
