Install GroupDocs.Metadata-Cloud from Maven

Add GroupDocs Cloud repository to your application pom.xml

<repository>
    <id>repository.groupdocs.cloud</id>
    <name>repository.groupdocs.cloud</name>
    <url>https://releases.groupdocs.cloud/java/repo/</url>
</repository>

Install from source

mvn clean install

To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:

mvn clean deploy

Refer to the OSSRH Guide for more information.

Maven users

Add this dependency to your project’s POM:

mvn clean package

Then manually install the following JARs:

• target/groupdocs-metadata-cloud-22.2.jar
• target/lib/*.jar

Get Started

Please follow the Quick Start instructions.

Extract metadata by partial Tag Name via Java Cloud SDK

// For complete examples and data files, please go to https://github.com/groupdocs-metadata-cloud/groupdocs-metadata-cloud-java-samples
String MyAppKey = ""; // Get AppKey and AppSID from https://dashboard.groupdocs.cloud
String MyAppSid = ""; // Get AppKey and AppSID from https://dashboard.groupdocs.cloud
   
Configuration configuration = new Configuration(MyAppSid, MyAppKey);
MetadataApi apiInstance = new MetadataApi(configuration);
 
ExtractOptions options = new ExtractOptions();
SearchCriteria searchCriteria = new SearchCriteria();
TagOptions tagOptions = new TagOptions();
tagOptions.setPossibleName("creator");
searchCriteria.setTagOptions(tagOptions);
options.setSearchCriteria(searchCriteria);
FileInfo fileInfo = new FileInfo();
fileInfo.setFilePath("documents/input.xlsx");
options.setFileInfo(fileInfo);
ExtractRequest request = new ExtractRequest(options);
 
ExtractResult response = apiInstance.extract(request);
