FasTnT EPCIS repository

FasTnT EPCIS is a lightweight GS1 EPCIS 1.2 and 2.0 repository written in C# using .NET8 and backed with EntityFramework Core.

The repository fully supports the following databases:

• SqlServer (provider: SqlServer)
• PostGreSQL (provider: Postgres)
• Sqlite (provider: Sqlite)

Environments and Testing

There is a sandbox available if you want to quickly test this EPCIS repository capabilities.

A Postman team is also available that contains collections for both XML/SOAP and JSON endpoints. Alternatively, a SoapUI project can be found in the source code that contains queries for the v1.2 implementation.

Setup

1. Download the source code: $ git clone https://www.github.com/louisaxel-ambroise/epcis && cd epcis
2. Apply database migrations: $ dotnet ef database update --project src/FasTnT.Host --connection "Data Source=fastnt.db;" -- --FasTnT.Database.Provider "Sqlite"
3. Start the repository: $ dotnet run --project src\FasTnT.Host\FasTnT.Host.csproj --urls "http://localhost:5102/" --connectionStrings:FasTnT.Database "Data Source=fastnt.db;" --FasTnT.Database.Provider "Sqlite"

That's it! You have a properly working EPCIS repository using Sqlite as storage.

You can replace the Connection String and Database Provider with the values that suits better your needs (Sqlite, SqlServer or PostGreSQL).

You can also setup FasTnT EPCIS using the Docker image or in Azure very easily. Check the wiki for more details.

HTTP Endpoints

The API is secured using HTTP Basic auth by default. The users are not stored in the database, but a hash of the authorization value is stored alongside the request. By default the events and masterdata returned in a query are restricted to the ones captured with the same authorization header.

EPCIS endpoints:

FasT&T provides a full implementation of the EPCIS 1.2 and 2.0 specification. The endpoints are:

• Capture: POST /Capture
• Query : GET /events
• SOAP Service : POST /Query.svc

Capture and Query endpoints supports requests with content-type: application/json (EPCIS v2.0), content-type: application/xml or content-type: text/xml header and JSON or XML payload.

Queries endpoint supports SOAP requests on endpoint /Query.svc.

See the wiki for more details.
