tom_specs_model — the TomSpecs Specification Object Model #

Cross-references. doc/index.md is the catalogue of the fourteen TomSpecs authority documents this package carries, and it owns the § citation convention used across all of them. doc/tom_specs_model_rules.md owns the model-authoring rules — field shapes, form decomposition, section ids, annotations, structural invariants — and doc/som_multiplatform_spec_model.md owns the nine-language generation and every serialization format. This README is the guide to this package's code: what it holds, how it is laid out, and how to depend on it; those documents own what the model must be and what the generator makes of it.

Typed Dart data model for all TomSpecs specification documents — the source of truth the SOM generator derives the nine language runtimes from.

Where this fits #

TomSpecs is a method for building software from structured specification documents: a project is written up as a set of typed documents, and the code skeleton is generated from them. tom_specs_model is the Dart source model that defines what those documents are — one class tree per document, carrying every section id, headline, form field, constraint and traceability link.

It exists so the definition has exactly one home. Nine languages ship a runtime for reading and writing TomSpecs documents, and a schema, a markdown serializer, a validator and an editor all have to agree on the same structure. Written nine times, they would agree on the day they were written and never again. Written once here, everything downstream is generated — the nine tom_som_<lang>_v0 facades, their runtimes, the DocSpecs schemas and the class outlines all derive from this tree, so they cannot drift from it.

It therefore sits at the top of the generation chain and the bottom of the dependency graph: it is annotated with tom_specs_core, read by tom_specs_clitool, and everything a consumer touches is generated out of it. It is also the version authority for the whole lockstep chain — the version in its pubspec.yaml is the TomSpecs model version, stamped by the versioner, read by the generator, and carried by all nine generated runtime/facade pairs.

Overview #

The package is a data model and nothing else — no I/O, no logic beyond serialization support. Its content is:

Fourteen document roots. D00SolutionBlueprint is the master document; D01–D12 are the Phase-3 detail documents derived from it; D13 is the flat CodeSpecs generation projection. Each is a class marked @Document.
One container. DocSpecsProject holds all fourteen roots, so the whole model has a single reachable root for the generator and the tooling to walk.
Shared types in lib/src/common/ — the enums, Requirement, Risk, DocumentHeader and section metadata that more than one document uses.
The generated SpecClassOps registry (lib/src/generated/spec_ops.g.dart), which gives every concrete class its snapshot and serialization contract, and wires each projection root onto the live D00SolutionBlueprint instance rather than onto default-constructed sections.

Every section class extends DocSpecsSection from tom_specs_core, so a *.md document parses back into the model with full headline and id fidelity.

What this package is (and is not) #

It is the model the generator reads: every class tree, section id, headline, form decomposition, traceability link and DocSpecs constraint that the nine generated runtimes and typed facades carry originates here.
It is not the package most consumers depend on. To author, read, validate, or extract from a specification document in Dart, depend on tom_som_dart_v0 (the generated typed facade) and its runtime tom_som_dart_runtime. Depend on tom_specs_model when you need the model source itself — to run the generator, or the model-level tooling in tom_specs_clitool.

Installation #

dependencies:
  tom_specs_model: ^1.1.0

dart pub add tom_specs_model

import 'package:tom_specs_model/tom_specs_model.dart';

The single barrel exports all fourteen document roots, the container, the shared types, and the serialization and snapshot support.

Features #

The document set #

Root class	Code	Document
`D00SolutionBlueprint`	SBP	Solution Blueprint — the master document every Phase-3 document derives from
`D01CurrentLandscapeAssessment`	CLA	Current landscape assessment
`D02TargetOperatingModel`	TOM	Target operating model
`D03InformationModel`	IFM	Information model
`D04RequirementsSpecification`	RSP	Requirements specification
`D05InteractionScenarios`	ISC	Interaction scenarios
`D06ArchitectureTechnologySpecification`	ATS	Architecture and technology specification
`D07IntegrationInterfaceSpecification`	IIS	Integration and interface specification
`D08SecurityAccessSpecification`	SAS	Security and access specification
`D09ExperienceDesignSpecification`	XDS	Experience design specification
`D10QualityAcceptancePlan`	QAP	Quality and acceptance plan
`D11DeliveryRoadmap`	DRM	Delivery roadmap
`D12TransitionRolloutPlan`	TRP	Transition and rollout plan
`D13CodeSpecsProjection`	CGP	The flat CodeSpecs generation projection

Which phase each document belongs to, and what a project does with it, is decided by doc/tom_specs_project_flow.md.

What is derived from this model #

Artefact	Produced by	Consumed by
`spec_model.meta.json` — the resolved class graph	`tom_specs_clitool`'s `ModelJsonExporter`	all nine SOM runtimes, the editor, the reviewer
Nine `tom_som_<lang>_v0` typed facades + `_runtime` pairs	`tom_specs_clitool/bin/generate_som.dart`	applications reading or writing specifications
DocSpecs schemas	`docspecs_schema_generator.dart`	document validation
Class-tree outlines (`generated-doc/outlines/`)	`tom_specs_clitool/tool/regenerate_outlines.sh`	review and documentation
The CodeSpecs area catalogue (`generated-doc/codespecs/`)	`tom_specs_clitool/bin/codespecs_areas.dart`	Phase-4 extract generation
`lib/codespecs_areas.dart` — the same catalogue as Dart	the same command, in the same pass	a Dart consumer that must not read a file

Because all of it is generated, a model edit is not finished until the generator has been re-run. That is enforced rather than remembered: the clitool fingerprints the model source, and a model change that never reached the nine packages fails its test suite.

Quick start #

// dart run example/tom_specs_model_example.dart
import 'package:tom_specs_model/tom_specs_model.dart';

void main() {
  final pd = D00SolutionBlueprint()
    ..documentControl.header.content =
        'SBP — Example Project v0.1 by Author (Draft)';
  print('Document: ${pd.documentControl.header.content}');
  // Document: SBP — Example Project v0.1 by Author (Draft)
}

Examples #

Sample	Demonstrates
example/tom_specs_model_example.dart	Constructing a Solution Blueprint root and writing its document header

Usage #

Working with the whole project #

DocSpecsProject is the single root over all fourteen documents. Constructing it registers the generated SpecClassOps contracts, so serialization and snapshotting work without a separate setup call.

import 'package:tom_specs_model/tom_specs_model.dart';

void main() {
  final project = DocSpecsProject();
  project.solutionBlueprint.documentControl.header.content =
      'SBP — Example Project v0.1 by Author (Draft)';

  // The Phase-3 roots hang off the same project.
  print(project.requirementsSpecification.runtimeType);
  // D04RequirementsSpecification
}

Authoring a new section #

A section is a class extending DocSpecsSection, annotated with the tom_specs_core vocabulary. What each annotation means, and which ones a given section must carry, is decided by tom_specs_model_rules.md — in particular its field-type rules (tom_specs_model_rules.md §6.1) and the seventeen structural invariants the validator enforces (tom_specs_model_rules.md §10.2).

Two mechanical steps follow every model edit, in this order:

cd ../tom_specs_clitool
dart run bin/stamp_serialization_order.dart   # renumber @SerializationOrder
dart run bin/generate_som.dart                # regenerate the nine runtimes
./tool/regenerate_outlines.sh                 # refresh generated-doc/outlines

The stamping step is not optional: the generator refuses to run past an unstamped member, so a member inserted where it belongs in the source gets its stamp from the tool rather than by hand.

`Requirement`, `Risk`, `DocumentHeader`	Shared types used by more than one document.
`SpecClassOps` (generated)	Per-class snapshot and serialization contract, keyed by section id rather than by Dart field name.

Further documentation #

TomSpecs subject matter — the fourteen authority documents, twelve carried in this package's own doc/ folder and the two CodeSpecs documents in tom_core_codespecs/doc/:

Document	Authority for
doc/index.md	The catalogue of the whole set, and the `§` citation convention
doc/tom_specs_model_rules.md	Model layout, field shapes, section ids, annotations, the structural invariants, and the outliner
doc/som_multiplatform_spec_model.md	The nine-language generation, the metadata tree, serialization, schemas, validation and packaging
doc/tom_specs_model_meta_schema.md	The on-disk schema of the generated `spec_model.meta.json`
doc/som_generator_config.md	The `tom-spec-object-model` generator config block
doc/som_toolchains.md	Per-language build and verify toolchains for the generated runtimes
doc/tom_specs_project_flow.md	The creation process — phases, quality gates, iteration rules, roles
codespecs_mapping.md	Which SOM section feeds which CodeSpecs part — the grounding document
codespecs_derivation_contract.md	What code comes out of Phase 4, per marker, and the validator checks
doc/codespecs_prompt.md	When a Phase-4 run may begin at all — the starting prompt and its gate
doc/tom_specs_editor_specification.md	The spec authoring application
doc/tom_specs_reviewer_specification.md	The object-model review application
doc/llm_and_d4rt_tools.md	The `tom_spec_engine` scripting plane — scopes, search, tools, memory
doc/llm_guidelines_specification.md	The in-editor agent's context prompt
doc/tom_specs_documentation_standard.md	What documentation every TomSpecs package carries, and when it is finished

Runnable samples — a whole task carried end to end across several packages, as opposed to this package's own example/: tom_specs_samples/ (doc/tom_specs_documentation_standard.md §7).

This package — its own guides, in doc/package/ so the two tiers stay visibly apart in the one folder that hosts both:

Guide	Covers
doc/package/index.md	The catalogue of this package's own documentation
doc/package/authoring_a_section_class.md	Writing a model class, and the stamp/regenerate/outline sequence that must follow
doc/package/document_roots.md	`DocSpecsProject`, the fourteen entry points, the projections and the two save paths
doc/package/snapshot_and_serialization.md	The per-class contract, copy-on-write snapshotting, and the projection onto the wire format
doc/api/api_summary_index.md	The per-module API summaries

Siblings — packages you will reach for next:

Package	What it is
tom_specs_core	The annotation vocabulary this model is written in
tom_specs_clitool	The generator, validator, outliner and citation gates that read this model
tom_som_dart_v0	The generated Dart facade — what a Dart consumer actually depends on
tom_som_dart_runtime	The generic Dart runtime behind that facade
tom_som_conformance	The harness proving the nine generated runtimes agree

Status #

Version 1.1.0, published on pub.dev. This version is the TomSpecs model version: it is stamped by the versioner, read by the SOM generator, and the nine generated runtime and facade packages are kept in lockstep with it.

Test suite: 43 tests, all passing (dart test).
