This repository holds all core domain logic about CESSDA Metadata Validator project.

## Prerequisites

The following SDKs must be installed before the project can be used.

* Java Development Kit (JDK) 8 (or later)

## Usage

This is a short snippet showing how to use the validator.

```java
void validateUsingFiles()
{
	CessdaMetadataValidatorFactory factory = new CessdaMetadataValidatorFactory();
	Document document = factory.newDocument( new File( "path/to/ddi-document.xml" ) );
	Profile profile = factory.newProfile( new File( "path/to/ddi-profile.xml" ) );
	ValidationReport validationReport = factory.validate( document, profile, BASIC );
	boolean isValid = validationReport.getConstraintViolations().isEmpty();
	validationReport.getConstraintViolations().forEach( cv -> System.out.println( cv.getMessage() ) );
}
```

For more detailed information, consult the JavaDoc.
