      <id>repository.groupdocs.com</id>
      <name>GroupDocs Repository</name>
      <url>https://releases.groupdocs.com/metadata/java/</url>
   </repository>
</repositories>

<dependencies>
   <dependency>
      <groupId>com.groupdocs</groupId>
      <artifactId>groupdocs-metadata</artifactId>
      <version>24.12</version>

License Acquisition Steps

Free Trial: Start with a free trial to test the features.
Temporary License: Apply for a temporary license for extended evaluation.
Purchase: Consider purchasing a license for long-term use.

Basic Initialization and Setup

To initialize GroupDocs.Metadata, create an instance of the Metadata class by providing the path to your document:

import com.groupdocs.metadata.Metadata;

// Initialize Metadata object with input file path
Metadata metadata = new Metadata("YOUR_DOCUMENT_DIRECTORY/input.vsdx");

This setup is your entry point into managing and querying metadata properties.

Implementation Guide

Search Metadata Properties by Tag

Overview

This feature allows you to search for specific metadata properties using predefined tags, which is particularly useful for filtering metadata based on categories like person-related information.

Step-by-Step Implementation

1. Import Required Classes

Start by importing the necessary classes:

import com.groupdocs.metadata.Metadata;
import com.groupdocs.metadata.core.IReadOnlyList;
import com.groupdocs.metadata.core.MetadataProperty;
import com.groupdocs.metadata.search.FallsIntoCategorySpecification;
import com.groupdocs.metadata.tagging.Tags;

2. Initialize Metadata Object

Create a Metadata object with the path to your document:

Metadata metadata = new Metadata("YOUR_DOCUMENT_DIRECTORY/input.vsdx");

3. Specify Tag Category

Define which category of tags you want to search for, such as person-related tags:

FallsIntoCategorySpecification specification = new FallsIntoCategorySpecification(Tags.getPerson());

4. Find Properties by Specification

Use the findProperties method to retrieve properties that match your criteria:

IReadOnlyList<MetadataProperty> properties = metadata.findProperties(specification);

5. Iterate and Display Properties

Loop through the found properties and print their names and values:

for (MetadataProperty property : properties) {
    System.out.println("Property name: " + property.getName() + ", Property value: " + property.getValue());
}

Troubleshooting Tips

Ensure your document path is correct.
Verify that the GroupDocs.Metadata library version matches your project setup.

Practical Applications

Document Management Systems: Automate metadata extraction for organizing digital assets.
Legal Document Processing: Efficiently extract and categorize personal information.
Content Management Platforms: Enhance search capabilities by tagging content with relevant metadata.

Integration possibilities include linking with databases or cloud storage solutions to streamline workflows.

Performance Considerations

Optimize Resource Usage: Close Metadata objects after use to free memory.
Efficient Tagging: Use specific tags to reduce unnecessary processing.
Memory Management Best Practices: Regularly monitor and manage Java heap space when handling large datasets.

Conclusion

You’ve now mastered the art of searching metadata properties by tag using GroupDocs.Metadata for Java. This powerful feature not only enhances your data management capabilities but also opens up new possibilities for document automation and organization.
