Detect PDF/A Conformance using GroupDocs.Metadata for .NET

🚀 Quick Start

Get started with GroupDocs.Metadata for .NET to detect PDF/A conformance in your documents. This repository provides a ready‑to‑run console example that demonstrates how to read a PDF, check its PDF/A compliance, and output the exact PDF/A version. Perfect for developers who need to verify archival quality of PDF files programmatically.

✨ What You'll Learn

• How to load a PDF file with the Metadata API
• How to access the root package and evaluate FileType.IsPdfA
• How to retrieve the specific PDF/A conformance level via FileType.PdfFormat
• How to handle non‑compliant PDFs gracefully
• How to integrate PDF/A validation into larger document‑processing pipelines
• Best practices for working with GroupDocs.Metadata in .NET projects

📖 About This Repository

This repository contains practical examples for implementing PDF/A conformance detection using GroupDocs.Metadata for .NET. GroupDocs.Metadata enables developers to read, modify, and validate metadata across a wide range of document formats, including PDF, Word, Excel, and more. These examples are designed for C# developers working with PDF/A archival documents who need to programmatically ensure compliance with ISO 19005 standards. Each example demonstrates real‑world scenarios and best practices for reliable metadata handling.

🔑 Key Features

GroupDocs.Metadata Capabilities

GroupDocs.Metadata provides powerful document processing capabilities:

Feature	Description
Metadata Extraction	Retrieve structured metadata from over 100 file formats.
Metadata Modification	Edit, add, or remove metadata without altering document content.
Compliance Validation	Validate documents against standards such as PDF/A, ISO 19005, and more.
Secure Document Handling	Work with encrypted or password‑protected files safely.
Cross‑Platform Support	Available for .NET, Java, Python, and Node.js ecosystems.

What This Repository Demonstrates

• Detecting PDF/A conformance and identifying the exact PDF/A version.
• Accessing the root package of a PDF through the PdfRootPackage class.
• Using the FileType.IsPdfA property to verify archival compliance.
• Handling both compliant and non‑compliant documents in a clean, readable way.

⚙️ Prerequisites

Before you begin, ensure you have:

• .NET SDK – .NET 6.0 or later.
• GroupDocs.Metadata for .NET – Install via NuGet (GroupDocs.Metadata).

File Overview

• Program.cs – Console application that loads a PDF, checks PDF/A compliance, and prints the detected version or a non‑compliance message.

💻 Implementation Examples

Example 1: Snippet: Detect PDF/A conformance and indicate the PDF/A version.

This example opens a PDF file, reads its root package, and determines whether the document conforms to PDF/A. If it does, the exact PDF/A version (e.g., PDF/A‑1b, PDF/A‑2u) is printed; otherwise, a message indicating non‑compliance is shown. The snippet demonstrates the core API calls Metadata, GetRootPackage<PdfRootPackage>(), and the FileType properties.

    using (Metadata metadata = new Metadata(path))
    {
        var root = metadata.GetRootPackage<PdfRootPackage>();

        if (root.FileType.IsPdfA)
        {
        }
        else
        {
        }
    }

What This Example Shows:

• How to instantiate the Metadata object with a file path.
• Retrieval of the PDF's root package using the generic GetRootPackage<T>() method.
• Checking the IsPdfA boolean to quickly determine compliance.
• Accessing FileType.PdfFormat (inside the omitted block) to obtain the specific PDF/A version when compliant.
• A clean, try‑with‑resources pattern (using) that ensures proper disposal of resources.
