Packata.Core 0.43.0

Packata

Packata is a standards-neutral .NET library for working with Data Package v2 and Open Data Contract Standard (ODCS) documents. It maps both formats to a shared model for data assets, schemas, metadata, and endpoints, with optional packages for reading and provisioning data.

About

Use the format-specific models when you need direct access to Data Package or ODCS concepts. Map either format to Packata.Core.Contracts.DataContract when you want readers, provisioners, and other integrations to work independently of the source document format.

Packages

Packata libraries target .NET 8, .NET 9, and .NET 10. The CLI targets .NET 10.

Installing

Install the package for the document format you use:

dotnet add package Packata.DataPackage

dotnet add package Packata.OpenDataContract

Add Packata.ResourceReaders, Packata.Storages, or Packata.Provisioners when your application needs those capabilities. Format packages reference Packata.Core, so it does not need to be installed separately.

Command-line tool

Install the framework-dependent .NET 10 tool from NuGet:

dotnet tool install --global Packata-cli
packata --help

Update an existing installation with dotnet tool update --global Packata-cli.

Self-contained executables that do not require an installed .NET runtime are available from the GitHub releases page. Select the archive for your platform:

Linux distributions using glibc must use a linux-* archive; Alpine and other musl-based distributions must use linux-musl-*. Extract the ZIP archive on Windows or the tar.gz archive on Linux/macOS, then invoke the executable directly. Packata does not publish a 32-bit Windows CLI.

Quickstart

Load a Data Package descriptor and map it to the standards-neutral model:

using Packata.DataPackage;
using Packata.DataPackage.Mapping;

var package = new DataPackageFactory().LoadFromFile("datapackage.json");

var contract = package
    .ToCanonicalContract()
    .ReportDiagnostics(diagnostic =>
        Console.Error.WriteLine($"{diagnostic.Severity}: {diagnostic.Message}"))
    .RequireValue();

foreach (var asset in contract.Assets)
    Console.WriteLine(asset.Name);

ODCS documents map to the same canonical model through the Packata.OpenDataContract.Mapping namespace. See MIGRATION.md for side-by-side mapping examples and guidance for upgrading from earlier Packata versions.
