Polyglot Package Registry

The Ansatz Package Registry (/packages) provides versioned dependency management and artifact distribution for multi-domain engineering libraries. It supports native ModelScript packages alongside standard Modelica libraries, SysML v2 models, and STEP CAD repositories.

Supported Package Formats

Format	Scope & Manifest	Primary Usage
ModelScript	package.json (modelscript field)	Native multi-domain models, equations, and simulation scripts
Modelica	package.mo / package.order	Complete Modelica 3.x packages and component libraries
SysML v2	sysml.library	OMG Systems Modeling Language v2 and KerML domain models
STEP CAD	step.json manifest	ISO 10303 AP214/AP242 geometric parts and assemblies
SSP Containers	SystemStructure.ssd	System Structure and Parameterization multi-FMU packages

Package Lifecycle

1. Authoring & Manifest Configuration

Packages include metadata declaring dependencies, license, and maturity:

{
  "name": "@engineering/microgrid",
  "version": "1.2.0",
  "license": "Apache-2.0",
  "dependencies": {
    "@modelscript/modelica": "^4.1.0",
    "@modelscript/pscad": "^0.0.18"
  }
}

2. Publishing Packages

Engineers can publish packages through the web interface using the Publish Package Modal in /packages, or via the CLI:

msx publish ./my-package

3. Dependency Resolution & Integrity

• Content-Addressable Storage: Published tarballs are stored and indexed by SHA-256 digest.
• SPDX License Auditing: Manifests are analyzed during upload to verify valid SPDX identifiers and flag incompatible license pairings.
• Dependency Trees: The registry computes transitive dependency graphs and displays required dependencies in the web UI.

Industry Standards & Export Gateways

Packages in the Ansatz registry can be exported into standardized industrial container formats with a single click:

• Asset Administration Shell (AASX): Generates an Industry 4.0 Asset Administration Shell package compatible with AASX Package Explorer.
• Open Know-How (OKH): Produces a DIN SPEC 3105 Open Know-How manifest (okh.json) for open-hardware traceability.
• ISO/PAS 81346 Digital Data Package (DDP): Packages system hierarchies according to international reference designation standards.
