Try a contract in LegalLab

LegalLab is a Windows desktop application for editing Legal Identities, contracts, and Neuro-Features. Build it from source, open an example from the repository, and save your own contract XML.

Before you start

You need Windows, Git, the .NET 8 SDK, and Internet access to restore the project’s packages. LegalLab targets net8.0-windows and uses WPF. You can edit a contract locally before connecting an account. Submitting it later requires the Agent API access and provider review described in the authoring guide.

1. Clone both repositories

Run these commands from the parent directory where you keep your projects:

git clone https://github.com/Trust-Anchor-Group/LegalLab.git
git clone https://github.com/Trust-Anchor-Group/MicrosoftInterop.git

Keep the folders side by side:

YourProjects/
  LegalLab/
    LegalLab/LegalLab.csproj
    ExampleContracts/
  MicrosoftInterop/
    TAG.Content.Microsoft/TAG.Content.Microsoft.csproj

LegalLab references the TAG.Content.Microsoft project using this relative layout. That library provides Word-to-Markdown conversion. See the LegalLab source project.

2. Build and start LegalLab

From the parent directory used above, enter the LegalLab clone and build it:

cd LegalLab
dotnet build LegalLab/LegalLab.csproj --configuration Release
dotnet run --project LegalLab/LegalLab.csproj --configuration Release --no-build

The build restores the required packages. The run command opens the desktop application.

3. Open an example from your clone

In Design, select Load and choose a file under ExampleContracts:

Example	What to learn
`Syntax/ParameterTypes.xml`	Parameter types and constraints.
`Syntax/CalculatedParameters.xml`	Expressions that calculate contract values.
`Tokens/Create/Specific/DemoToken.xml`	A token creation contract.

Start with ParameterTypes.xml. The LegalLab example catalog explains the roles, parameters, and schema dependencies of the other examples.

4. Edit and save a copy

Inspect General Information, Roles, Parameters, and the human-readable text. Change one label or default parameter value, then select Save and choose a new filename. Load your saved file again and confirm the change is present. Validate the complete XML before submitting it.

5. Submit through the Agent API

Use your saved XML in Propose the template. That guide continues through provider approval, instance creation, review, and signing.

If the build or load fails

Problem	What to check
Referenced project missing	Both repositories must be sibling directories named exactly as shown above.
Windows desktop target unavailable	Build on Windows with the .NET 8 SDK installed.
Package restore fails	Check access to the package sources used by the projects and the reported package error.
XML fails to load	Confirm the complete file and its schema dependencies using the example catalog and validation guide.
