File Analyzer Component Packages - Georgetown-University-Libraries/File-Analyzer GitHub Wiki

The File Analyzer code base is broken into multiple modules containing different levels of functionality.

Core Package - requires only Java

The Core package contains File Test Rules and File Import Rules

with general applicability to multiple institutions
that do not depend on libraries other than the core java libraries

Core Package Contents

Core Utils package

The Core Utils package contains utility classes that my be re-used outside of the FileAnalyzer.

Demo Package

The Demo package is integrated with Apache Tika (for metadata extraction), BagIt, and Marc4j

The Demo package contains File Test Rules and File Import Rules

that depend on external libraries
may not have applicability to multiple institutions
demonstrate how to customize Core code to implement institution-specific business logic

Demo Package Contents

Demo Package Contents Using Marc4j

Bag Utils package

The Bag Utils package contains utility classes that my be re-used outside of the FileAnalyzer. The purpose of this package is to share File Analyzer logic for non-interactive use.

The Bag Utils package uses BagIt and Apache Commons Cli.

DSpace Package - automation of DSpace ingestion tasks

Georgetown University has successfully automated a number of DSpace ingest tasks using the File Analyzer.

See DSpace Institutional Repository Ingest for an illustration of these tools

Custom Packages

An institution can create their own module containing highly customized rules.

Create Your Own File Analyzer

public class GUFileAnalyzer extends DirectoryTable {

public GUFileAnalyzer(File f, boolean modifyAllowed) {
    super(f, modifyAllowed);
    this.title = "Georgetown University Libraries File Analyzer";
    this.message = "File Analyzer customized for use by the Georgetown University Libraries.";
    this.refreshTitle();
}

protected ActionRegistry getActionRegistry() {
    return new GUActionRegistry(this, modifyAllowed);
}

protected ImporterRegistry getImporterRegistry() {
    return new GUImporterRegistry(this);
}
public static void main(String[] args) {
    if (args.length > 0)
        new GUFileAnalyzer(new File(args[0]), false);        
    else
        new GUFileAnalyzer(null, false);        
}

}

Create an ActionRegistry to register your custom File Test Rule classes (and to remove default ones)

public class GUActionRegistry extends DemoActionRegistry {

private static final long serialVersionUID = 1L;

public GUActionRegistry(FTDriver dt, boolean modifyAllowed) {
    super(dt, modifyAllowed);
    
    removeFT(IngestInventory.class);
    removeFT(IngestValidate.class);
    add(new GUIngestInventory(dt));
    add(new GUIngestValidate(dt));
}

}

Create an ImporterRegistry to register your Custom File Import Rules

public class GUImporterRegistry extends DemoImporterRegistry {

private static final long serialVersionUID = 1L;

public GUImporterRegistry(FTDriver dt) {
    super(dt);
    add(new OutputToBursar(dt));
}

}
