# ZB.MOM.WW.Configuration
|
|
|
|
Startup configuration-validation library for the **ZB.MOM.WW SCADA family** (OtOpcUa, MxAccessGateway, ScadaBridge). These are **libraries, not a service** — the package is linked directly into the consuming application at build time. There is no central validation process; all validation runs in-process at startup.
|
|
|
|
The library normalizes the three-project configuration-validation surface: a failure-accumulating `IValidateOptions` base, reusable rule primitives, a bind+validate+`ValidateOnStart` DI extension, and a pre-host `ConfigPreflight` aggregator for raw `IConfiguration` — so the plumbing is written once and domain rules stay per-project.
|
|
|
|
**Built at 0.1.0. Not yet adopted by OtOpcUa, MxAccessGateway, or ScadaBridge.** Adoption tracked in `~/Desktop/scadaproj/components/configuration/GAPS.md`.

## Package
|
|
|
|
| Package | Responsibilities | Key Dependencies |
|
|
|---|---|---|
|
|
| `ZB.MOM.WW.Configuration` | `OptionsValidatorBase<TOptions>` (abstract `IValidateOptions` base, failure-accumulating), `ValidationBuilder` (rule primitives: `Required`, `Port`, `HostPort`, `PositiveTimeSpan`, `OneOf`, `MinCount`, `RequireThat`, `Add`), `ServiceCollectionExtensions.AddValidatedOptions` (bind + validator + `ValidateOnStart` in one call), `ConfigPreflight` (fluent pre-host raw-`IConfiguration` checker). | `Microsoft.Extensions.Options`, `Microsoft.Extensions.Options.ConfigurationExtensions`, `Microsoft.Extensions.Configuration.Abstractions`, `Microsoft.Extensions.DependencyInjection.Abstractions` |
|
|
|
|
Single package; no ASP.NET Core framework reference.

## Build, test, and pack commands
|
|
|
|
```bash
|
|
# From ZB.MOM.WW.Configuration/
|
|
|
|
# Build
|
|
dotnet build ZB.MOM.WW.Configuration.slnx
|
|
|
|
# Test (no external dependencies required)
|
|
dotnet test ZB.MOM.WW.Configuration.slnx
|
|
|
|
# Pack (one .nupkg lands in artifacts/)
|
|
dotnet pack ZB.MOM.WW.Configuration.slnx -c Release -o ./artifacts
|
|
```
|
|
|
|
Test breakdown:
|
|
|
|
| Assembly | Tests |
|
|
|---|---|
|
|
| `ZB.MOM.WW.Configuration.Tests` | 27 |
|
|
| **Total** | **27** |
|
|
|
|
`GeneratePackageOnBuild` is off — pack explicitly with the command above.

## Status
|
|
|
|
Part of the **scadaproj component-normalization family** — this is the configuration + validation component. Built at **0.1.0**. **Not yet adopted by OtOpcUa, MxAccessGateway, or ScadaBridge** — follow-on adoption is tracked in:
|
|
|
|
- `~/Desktop/scadaproj/components/configuration/GAPS.md`
|
|
|
|
Design documentation:
|
|
|
|
- `~/Desktop/scadaproj/components/configuration/spec/SPEC.md` — normalized validation target
|
|
- `~/Desktop/scadaproj/components/configuration/shared-contract/ZB.MOM.WW.Configuration.md` — proposed shared-library API
|
|
- `~/Desktop/scadaproj/components/configuration/current-state/` — per-project current state (code-verified)
