TALXIS Platform Metadata
An open-source metadata model for model-driven platforms. Provides typed C# representations of entities, attributes, forms, views, option sets, solutions, and solution layers - compatible with Dataverse and Power Platform.
What this is
A shared kernel that defines what platform components are and how they behave. It doesn't store data, execute plugins, or run workflows - it's the type system that all of those depend on.
Who uses it
| Consumer | How |
|---|---|
| TALXIS CLI | Workspace validation, component scaffolding, language server |
| TALXIS Build SDK | Build-time schema validation, version stamping |
| TALXIS Templates | Post-action scripts for safe workspace manipulation |
| Future: runtime services | Metadata management, solution import/export, query planning |
Capabilities
Metadata Model (TALXIS.Platform.Metadata)
Typed representations of platform component metadata:
- Entity - table definitions with ownership, activity type, audit settings
- Attribute - column definitions with types, constraints, option sets
- Relationship - 1:N, N:1, N:N with cascade behavior
- OptionSet - global and local choice definitions with localized labels
- Form - form XML structure (tabs, sections, controls)
- View - saved queries with FetchXML and layout
- Security Role - privilege definitions
- Plugin/Workflow - registration metadata
Solution Model (TALXIS.Platform.Metadata.Solutions)
- Solution - component registry, publisher, version
- Component definitions - per-type behavior (mergeable, overwritable, dependency rules)
- Layers - managed/unmanaged stacking, active layer resolution, merge behavior
Serialization (TALXIS.Platform.Metadata.Serialization)
- SolutionPackager format - bidirectional XML ↔ model mapping
- Roundtrip fidelity - Load → Save with no changes = zero git diff
- Minimal writes - only modified files are written
- Unknown element preservation - forward compatibility
Validation (TALXIS.Platform.Metadata.Validation)
- XSD schema validation - 23 component schemas
- Structural rules - duplicate GUIDs, missing references, naming conventions
- Constraint checking - attribute limits, option set value ranges
Design Principles
- Roundtrip safe - the model preserves everything it reads, even elements it doesn't understand
- Layered - components know about solution layers, not just the active (merged) state
- Validating - constraints are enforced in-memory, not just at serialization time
- No runtime dependencies - pure model library, no Dataverse SDK, no HTTP, no SQL
- netstandard2.0 - maximum compatibility (MSBuild tasks, scripts, CLI, runtime services)
Status
🚧 Design phase - see docs/ for architecture documents and roadmap.
