public class ExampleDataPackageUpload
extends Object

Utility for uploading data packages to a MN. Operates on a directory containing data package files accompanied by system metadata documents Traverses data package directories contained in PACKAGE_DIR class attribute. Each directory should contain the contents of a data package including the RDF/ORE file. The directory should also contain the system metadata document for each document in the package. Suffix the class attribute SYSMETA_SUFFIX value (.SYSMETA) to the end of the system metadata documents. Each file is uploaded to TARGET_MN_BASE_URL member node using java dataone libclient MNode class. Can also be used to copy data packages from a CN to a MN using the copyDataPackages method. TODO:: Check size of data files before downloading to avoid GB's of d/l and u/l.

Method Detail

main

public static void main(String[] args)
                 throws ServiceFailure

Demonstrates copying data package from a source CN to a target MN. Copies data packages based on a solr query that returns resource map identifiers.

Parameters:

args -

Throws:

ServiceFailure

copyDataPackages

public void copyDataPackages(CNode sourceCN,
                             MNode targetMN,
                             List<Identifier> oreIdentifiers)

Copy oreIdentifers from sourceCn to targetMN. Each data package is downloaded to tmp directory within PACKAGE_DIR along with science metadata documents. The data package is the uploaded to targetMN.

Parameters:

sourceCN -

targetMN -

oreIdentifiers -

uploadDataPackages

public void uploadDataPackages(MNode targetMN,
                               File rootDir)

Uploads data packages in rootDir to targetMN. Descends into directories contained in rootDir directory. Assumes each directory within rootDir contains a data package. Each data package directory should contain all documents/files of the data package - including files for system metadata for each part of the data package. System metadata files are suffixed with SYSMETA_SUFFIX value (".SYSMETA").

Parameters:

targetMN -

rootDir -

uploadDataPackageWithRetry

public boolean uploadDataPackageWithRetry(MNode targetMN,
                                          File tmpDir,
                                          int uploadRetries)

Uploads data package in tmpDir to targetMN. Each data package directory should contain all documents/files of the data package - including files for system metadata for each part of the data package. System metadata files are suffixed with SYSMETA_SUFFIX value (".SYSMETA").

Parameters:

targetMN -

tmpDir -

uploadRetries -
