Project Documentation
This document describes how to operate the Harvest Tool software for use with PDS4 data product registration. The following topics can be found in this document:
Note: The command-line examples in this section have been broken into multiple lines for readability. The commands should be reassembled into a single line prior to execution.
This section is intended to give a quick and easy way to set up the Harvest policy configuration file and run the tool. For a more detailed explanation on other ways to set up the policy configuration file as well as other ways of running the tool, go to the Harvest Policy File and Advanced Usage sections.
Included in the Harvest package is an example policy configuration file for PDS4 product registration. Go to the examples/ folder, make a copy of the harvest-policy-example.xml file and modify it as necessary. The following breaks down the policy file example and indicates what modifications are to be performed.
Registry Package
<registryPackage>
<name>Harvest Package Example Bundle Run</name>
<description>This is a Harvest run of the example bundle.</description>
</registryPackage>
Specify a Registry package name and description. This allows the Registry to associate registered products of a Harvest run to a particular package.
Collections
<collections>
<file>$HOME/dph_example_archive_VG2PLS/browse/Collection_browse.xml</file>
<file>$HOME/dph_example_archive_VG2PLS/context/Collection_context.xml</file>
<file>$HOME/dph_example_archive_VG2PLS/data/Collection_data.xml</file>
<file>$HOME/dph_example_archive_VG2PLS/document/Collection_document.xml</file>
<file>$HOME/dph_example_archive_VG2PLS/xml_schema/Collection_xml_schema.xml</file>
</collections>
Specify collection products here. This allows Harvest to be able to distinguish between primary members and secondary members of a collection while traversing a target directory.
Directories
<directories>
<path>$HOME/dph_example_archive_VG2PLS</path>
<fileFilter>
<include>*.xml</include>
</fileFilter>
</directories>
Specify the top level directory for Harvest to crawl for products to register.
Access URLs
<accessUrls registerFileUrls="false">
<accessUrl>
<baseUrl>http://starbase.jpl.nasa.gov</baseUrl>
<offset>$HOME</offset>
</accessUrl>
</accessUrls>
Specify the base URL of where the physical data products are located. This allows Harvest to provide links to the physical data products in the slots of each registered product in the Registry.
Checksums
<checksums generate="true">
<manifest>$HOME/dph_example_archive_VG2PLS/bundle_checksums.txt</manifest>
</checksums>
Specify a Checksum Manifest file. With this configuration, Harvest will generate checksums for each file object to be registered and compare against the supplied checksums in the data product label as well as the manifest file.
Candidate Products
<candidates>
...
<productMetadata objectType="Product_Browse">
<xPath slotName="information_model_version">
//Identification_Area/information_model_version
</xPath>
...
<candidates>
Specify any additional product types for Harvest to register here. Note that Harvest reads in an internal global policy config which already includes the following product types:
Additionally, the candidates section in this policy config example already specifies the following product types:
For the Product_Observational area:
<productMetadata objectType="Product_Observational">
<!-- Identification_Area -->
<xPath slotName="information_model_version">
//Identification_Area/information_model_version
</xPath>
<xPath slotName="product_class">
//Identification_Area/product_class
</xPath>
<xPath slotName="alternate_id">
//Identification_Area/Alias_List/Alias/alternate_id
</xPath>
<xPath slotName="alternate_title">
//Identification_Area/Alias_List/Alias/alternate_title
</xPath>
<xPath slotName="citation_author_list">
//Identification_Area/Citation_Information/author_list
</xPath>
...
</productMetadata>
add XPaths, as well as a meaningful slot name, for the <Discipline_Area> and <Mission_Area> metadata of interest to be included for every Product_Observational registration.
Note that the XPaths already defined in the example policy should not be modified as it allows the Registry to be populated with a consistent set of metadata for every product that is registered.
Namespaces
It is highly encouraged to define this in the policy when specifying XPaths to metadata that reside in a namespace other than the default PDS namespace. Doing so will make the policy more readable.
As an example, check out this PDS4 data product label here, which contains metadata within the <Discipline_Area> and <Mission_Area> sections that reside in namespaces other than the default PDS namespace. To extract metadata from these sections, do the following:
Set the namespaces in the candidates section of the policy config file:
<candidates>
<namespace prefix="disp" uri="http://pds.nasa.gov/pds4/disp/v1"/>
<namespace prefix="sp" uri="http://pds.nasa.gov/pds4/sp/v1"/>
<namespace prefix="geom" uri="http://pds.nasa.gov/pds4/geom/v0"/>
<namespace prefix="sbn" uri="http://pds.nasa.gov/pds4/sbn/v0"/>
<namespace prefix="epoxi" uri="http://pds.nasa.gov/pds4/mission/epoxi/v0"/>
...
</candidates>
Then add the additional XPaths to extract metadata within the <Discipline_Area> and <Mission_Area> sections from Product_Observational products:
<productMetadata objectType="Product_Observational">
...
<!-- Mission_Area metadata -->
<xPath slotName="spacecraft_clock_start_count">
//Mission_Area/epoxi:EPOXI_Attributes/epoxi:Observation_Parameters/epoxi:spacecraft_clock_start_count
</xPath>
<xPath slotName="spacecraft_clock_stop_count">
//Mission_Area/epoxi:EPOXI_Attributes/epoxi:Observation_Parameters/epoxi:spacecraft_clock_stop_count
</xPath>
<xPath slotName="total_integration_time">
//Mission_Area/epoxi:EPOXI_Attributes/epoxi:Observation_Parameters/epoxi:total_integration_time
</xPath>
<!-- Discipline_Area metadata -->
<xPath slotName="start_julian_date">
//Discipline_Area/sbn:Times/sbn:start_Julian_date
</xPath>
<xPath slotName="display_settings_local_reference_type">
//Discipline_Area/disp:Display_Settings/disp:Local_Internal_Reference/disp:local_reference_type
</xPath>
<xPath slotName="special_characteristics_local_identifier_reference">
//Discipline_Area/sp:Spectral_Characteristics/sp:local_identifier_reference
</xPath>
<xPath slotName="geometry_vertical_display_direction">
//Discipline_Area/geom:Geometry/geom:Image_Display_Geometry/geom:Display_Direction/disp:vertical_display_direction
</xPath>
</productMetadata>
</candidates>
Note that the XPaths are utilizing the prefix values from the namespaces defined in the policy.
The following table describes the command-line options available:
| Command-Line Option | Description |
|---|---|
| -c, --config | Specify a policy configuration file to set the tool behavior. (This flag is required) |
| -u, --username | Specify a username for authentication with the PDS Security Service. |
| -p, --password | Specify a password associated with the username. |
| -k, --keystore-pass | Specify a keystore password associated with the keystore file being passed into the tool. |
| -l, --log-file | Specify a log file name. Default is standard out. |
| -v, --verbose | Specify the message severity level and above to include in the log (0=Debug, 1=Info, 2=Warning, 3=Error). Default is Info and above (level 1). |
| -e, --regexp | Specify file patterns to look for when registering products from a target directory. Each pattern must be surrounded by quotes (i.e. -e "*.xml"). |
| -D, --ignore-dir | Specify patterns to look for when traversing a target directory for sub-directories to ignore. Each pattern must be surrounded by quotes (i.e. -D "CATALOG"). |

| -h, --help | Display harvest usage. |
This section describes more advanced ways to run the tool, as well as its behaviors and caveats.
The Harvest Tool operates with a policy file to register product metadata. Details on how to create this policy file can be found in the Harvest Policy File section.
This section demonstrates some of the other ways that the tool can be executed:
Registering Products From a Single Target
The following command demonstrates how to register products to a non-secured registry instance from a target directory, $HOME/directory, where only files that end with a .xml file extension, will be processed:
% harvest $HOME/directory -e "*.xml" -c policy.xml
Registering Products From Multiple Targets
The following command demonstrates how to register products to a non-secured registry instance from two target directories, $HOME/directory1 and $HOME/directory2, using the policy file, policy.xml. Only files that end with a .xml file extension will be processed. The output will go to a log file, log-file.txt:
% harvest $HOME/directory1, $HOME/directory2 -e "*.xml" -c policy.xml -l log-file.txt
Registering Products From Targets Specified In The Policy File
Targets can either be specified on the command-line or in in the policy file. Any targets specified on the command-line will overwrite any targets specified in the policy file. The following command demonstrates registering products based on targets specified in the policy file, policy.xml:
% harvest -c policy.xml
Registering Products To A Secured Registry Instance
The following command demonstrates how to register products to a secured registry instance from a target directory, $HOME/directory, using the policy file, policy.xml:
% harvest $HOME/directory -c policy.xml -u {username} -p {password} \
-k {keystorePassword}
Excluding Sub-Directories To Traverse From a Target
The following command demonstrates registering products from a target directory, $HOME/directory, where the tool will not traverse the sub-directory CONTEXT:
% harvest $HOME/directory -c policy.xml -D "CONTEXT"
The Harvest Tool can be run in persistence mode through an XML-RPC accessible web service called a daemon. Under this scenario, the Harvest Tool wakes up periodically, inspects a target directory or directories, and registers the latest products. This section details how to set this up.
In order to run the tool through the daemon, the command-line option flags -P and -w need to be used. This tells the Harvest Tool the port number to use and how long to sleep in between crawls, respectively. When the daemon is running, it can be accessed through the following url: http://localhost:{port number}/xmlrpc. The following command demonstrates launching the Harvest Tool through the daemon on port 9001, where it will wait 120 seconds in between crawls:
% harvest -c policy.xml -u {username} -p {password} \
-k {keystorePassword} -l log.txt -P 9001 -w 120
After running the above command, the daemon will be accessible at http://localhost:9001/xmlrpc.
In order to stop the daemon from running, a daemon controller is needed. The bin/ directory of the Harvest Tool release package contains a shell script, harvest-ctrl, and a batch file, harvest-ctrl.bat, which are used to gracefully shut down the daemon service on a UNIX-like and Windows system, respectively. In addition, they can provide a few additional statistics about the crawling.
The following table describes the command-line options available for harvest-ctrl:
| Command-Line Option | Description |
|---|---|
| --url | Specify the URL of the daemon service running the Harvest Tool. |
| --operation | Specify a single operation to perform. List of valid operations can be found in the next table. |
The following table describes the operation names available to pass with the --operation command-line option:
| Operation Option | Description |
|---|---|
| --stop | Specify this operation to shut down the daemon service. |
| --isRunning | Gives an indication whether the daemon service is running. |
| --getNumCrawls | Returns the number of crawls that have occurred. |
| --getWaitInterval | Returns the time, in seconds, that the crawler has to wait in between crawls. |
| --getMilisCrawling | Returns the amount of milliseconds spent crawling. |
| --getAverageCrawlTime | Returns the average amount of time, in milliseconds, spent during each crawl. |
The following examples demonstrate how to run harvest-ctrl using a few of the different operations. For demonstration purposes, assume that the daemon service is located at the following url: http://localhost:9001/xmlrpc.
Determine the Status of the Daemon Service
The following command is used to find out if the daemon service is still running:
% harvest-ctrl --url http://localhost:9001/xmlrpc --operation --isRunning
Shutdown the Daemon Service
The following command demonstrates shutting down the daemon service:
% harvest-ctrl --url http://localhost:9001/xmlrpc --operation --stop
The Harvest policy file is an XML-based configuration file that the tool uses to find products and register their metadata. The schema for the policy file can be found in the Harvest Policy Schema section. This section describes the valid elements that are available to setup the policy file to do PDS4 data product registration.
The following is an example of a policy file to perform registration of PDS4 data products:

</policy>
The policy file is made up of the following complex type elements: registryPackage, collections, directories, checksums, storageIngestion, accessUrls, candidates, and productMetadata.
registryPackage
Each time the Harvest Tool runs, it creates a package in the registry to group the product registrations together. Specify this element to give a registry package a name and/or description. The following table describes the elements that are allowed:
| Element Name | Description |
|---|---|
| name | Specify a package name. If this element is not specified, the default is to create a package with the name Harvest-Package_<current datetimestamp>. |
| description | Specify a package description. If this element is not specified, the default is to create a description that lists the targets that were specified in the policy config file. |
collections
Specify this element to tell the Harvest Tool to register the collections first before crawling a target directory. This is required if the target directory contains collections that are co-located with its members and in order to distinguish primary versus secondary members.
The following table describes the elements that are allowed:
| Element Name | Description |
|---|---|
| file | Specify a collection file. Specify this element tag more than once to point to multiple collection files. |
In the example above, the Harvest Tool will register the following collections before crawling the target directory:
Once these collections are registered, the primary and secondary members are cached in memory and as the Harvest Tool crawls through a target directory, any secondary members will be identified and will not be registered. In addition, a SKIP message will be issued in the log report to indicate that the tool has identified a non-primary member.
In the case where the target directory consists of a hierarchy structure where the collection product is located one-level above its members, much like the PDS context bundle, then there is no need to specify the collections in the Harvest policy config file. Under this scenario, the collections will be registered first before the Harvest Tool traverses down the sub-directory containing the members.
directories
Specify this element to tell the Harvest Tool where to crawl for data products. The following table describes the elements that are allowed:
| Element Name | Description |
|---|---|
| path | Specify a directory path to start crawling. Specify this element tag more than once to point to multiple directories to crawl. |
| fileFilter | Specify one or more include elements, where each element value contains a pattern to look for when crawling a target directory for files to register. If omitted, the default is to get all files within a directory. |
| directoryFilter | Specify one or more exclude elements, where each element value contains a pattern to look for when crawling a target directory for sub-directories to ignore. |
In the example above, the Harvest tool will crawl the directory location, $HOME/VG2PLS_archive, looking for files that have a .xml file extension. The default is to touch all files in the directory if the filePattern element is omitted from the policy file. In addition, the CONTEXT directory will be ignored while traversing the target directory.
accessUrls
Specify this element to provide links to the physical data products. The links will be placed in the registry as slots under the slot name accessUrl. An optional attribute can be specified named registerFileUrls, which if set to true, will create file url links.
The accessUrls element can contain multiple accessUrl element tags. The following table describes the elements that are allowed within the accessUrl tag:
| Element Name | Description |
|---|---|
| baseUrl | Specify a base url. |
| offset | Optionally specify an offset to nix from the absolute path of each product before appending it to the base url. Can be specified more than once. |
In the policy example above, the Harvest Tool will nix any absolute path of a product starting with $HOME before appending it to the starting base url of http://pds.nasa.gov/pds4. The following example demonstrates what the resulting access url will be for a registered product located at $HOME/VG2PLS_archive/browse/Collection_Browse.xml:
http://pds.nasa.gov/pds4/VG2PLS_archive/browse/Collection_Browse.xml
checksums
Checksum generation is turned off by default in the Harvest Tool. In order to turn this on, set the generate attribute to true. The following table describes the elements that are allowed within the checksum tag:
| Element Name | Description |
|---|---|
| manifest | Specify a checksum manifest file. Can be specified more than once. |
The following describes the tool behavior based on the different checksum settings:
Checksum Manifest File Provided and Generate Flag Set To true
Harvest will generate a checksum for each file encountered and verify it against the supplied checksum file. If the data file checksum was supplied in the label, Harvest will verify it as well. A warning message will be issued in the log report if a mismatch occurs. In any case, the generated checksum value is included in the associated Product_File_Repository product.
Checksum Manifest File Provided and Generate Flag Set To False (or not set at all)
Harvest will not generate checksums, but will use the value from the checksum manifest file to populate the associated Product_File_Repository product. If a data file checksum was supplied in the label, compare the value from the manifest against the value supplied in the label and issue a warning if there is a mismatch.
Checksum Manifest File Not Provided and Generate Flag Set To True
Harvest will generate a checksum for each file encountered and verify it against an optional checksum supplied in the label. If there is a mismatch, a warning message will be issued in the log report. The generated value is included in the associated Product_File_Repository product.
Checksum Manifest File Not Provided and Generate Flag Set To False
Harvest will not generate checksums. If the data file checksum was supplied in the label, populate the associated Product_File_Repository product with that value.
storageIngestion
Specify this element to tell the Harvest Tool to ingest data products to the PDS Storage Service. The following table describes the elements that are allowed:
| Element Name | Description |
|---|---|
| serverUrl | Specify the url to the PDS Storage Service. |
In the example above, the Harvest Tool will ingest data products to the PDS Storage Service at http://localhost:9000. When a data product is ingested to the PDS Storage, it returns a product id which is a reference to the ingested product. This id is placed as a slot in the registry under the slot name storageServiceProductId.
candidates
Specify this element to tell the Harvest Tool what product types to register and what metadata to extract from a data product. This is a required element in the policy file. The following table describes the elements that are allowed:
| Element Name | Description |
|---|---|
| namespace | Specify to allow the Harvest Tool to extract metadata that is in a namespace other than the default PDS namespace. |
| productMetadata | Specify to tell the tool what object types and what metadata to register. |
By default, the Harvest Tool defines the default namespace to be the PDS namespace. To override this default, specify the default attribute in the namespace element and give it a value of true. The following sets the dph namespace to be the default namespace in Harvest:
<candidates>
<namespace prefix="dph" uri="http://pds.nasa.gov/schema/pds4/dph/v01" default="true"/>
...
Namespaces need to be defined in the Harvest policy file only if the metadata to be extracted exists in a namespace other than the PDS namespace. In the example above, a namespace with the prefix dph and uri http://pds.nasa.gov/schema/pds4/dph/v01 has been defined. This means that any xPath expressions defined in the policy file will be able to use the dph prefix to be able to extract metadata that are within the dph namespace. xPaths will be explained in greater detail in the productMetadata section.
productMetadata
Specify this element to tell the Harvest Tool what metadata to register. It requires an attribute called objectType that tells the Harvest Tool what product types to register. The following table describes the elements that are allowed:
| Element Name | Description |
|---|---|
| xPath | Specify an XPath expression to extract metadata. |
In the example above, the policy file tells the Harvest Tool to look for and register the Product_Document and Product_Observational object types.
Also in the example is a set of xPath elements found under each productMetadata element. This defines what metadata to extract from the different products. XPath is a query language that uses path expressions to select nodes in an XML document. These path expressions look very much like expressions in a traditional computer file system. In its simplest form, prepending a // before a name will find the element no matter where it is in the XML file.
The following XPath expression will find the start_date_time element within the default namespace, no matter where this element is located in the file:
//start_date_time
The following XPath expression will find the spacecraft_clock_start_count element within the dph namespace, no matter where this element is located in the file:
//dph:spacecraft_clock_start_count
The following XPath expression will find all information_model_version elements that are children of Identification_Area within the default namespace:
//Identification_Area/information_model_version
The following XPath expression will find all name elements that are children of Target_Identification and that have a value of MARS:
//Target_Identification/name[text()="MARS"]
For a more detailed explanation on XPath, go to your favorite search engine and type XPath tutorial.
The slotName attribute within the xPath element allows the renaming of metadata element names when they are registered as slots in the registry. By default, the slot name is set to the element name that results from an xpath expression. For example, for the xpath expression, //Target_Identification/name, the slot name will be set to name.

This section describes the contents of the Harvest Tool report. At this time, the Harvest Tool only outputs a series of log messages. The log will report the success or failure of a discovered product attempting to be registered. Additionally, any syntactical errors in a discovered product are reported. A log consists of a severity level, file name, and a message. The following is an example of some of the log messages that can be expected from the Harvest Tool:

Execution of the Harvest Tool may result in the following message appearing in the log:
INFO: XML extractor set to the following default namespace: \
http://pds.nasa.gov/schema/pds4/pds
INFO: [/pds4/VG2PLS_archive/Product_Bundle.xml] Begin processing.
SKIP: [/pds4/VG2PLS_archive/Product_Bundle.xml] No product_class element found.
The message above is normally the result of a namespace mismatch between the Harvest Tool configuration and the product labels being registered. See the PDS4 Data Product Registration section above for details on specifying the namespace in the configuration file. By the way, the message could be telling the truth where the product label does not contain the <product_class> element. If this is the case, then the file is not a valid PDS product label.
