Operation

This document describes how to operate the Harvest-PDAP Tool software. The following topics can be found in this document:

• Tool Execution
• Policy File
• Report Format

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.

Tool Execution

Harvest-PDAP Tool can be executed in various ways. This section describes how to run the tool, as well as its behaviors and caveats.

% harvest-pdap -c policy.xml -l output.log
        

% harvest-pdap -c policy.xml -u {username} -p {password} -k {keystorePassword} \
-l output.log
        

Policy File

The Harvest-PDAP policy file is an XML-based configuration file that the tool uses to find products and register their metadata. This section details how to setup the policy file to do PDS product registration. The following is an example of a policy file to perform registration of ESA/PSA products:

<policy>
   <pdsRegistry url="http://localhost:8080/registry">
     <packageName>Harvest-PDAP Package</packageName>
     <packageDescription>
       This is a run that includes registration of products from the PSA.
     </packageDescription>
   </pdsRegistry>
   <pdapServices>
     <!-- Currently, the only valid value for 'agency' is 'esa'. -->
     <pdapService agency="esa" url="http://psa.esac.esa.int:8000"/>
   </pdapServices>
   <productMetadata>
     <!--
       All context product metadata definitions are captured in the 
       global policy. 
     -->
   </productMetadata>
   <resourceMetadata>
     <title>The Planetary Science Archive METADATA Query Service</title>
     <type>System.Browse</type>
     <slot name="resource_name">
       <value>The Planetary Science Archive METADATA Query Service</value>
     </slot>
     <slot name="resource_description">
       <value>The Planetary Science Archive METADATA Query Service</value>
     </slot>
   </resourceMetadata>
</policy>
      

The policy file is made up of the following complex type elements: pdsRegistry, pdapServices, productMetadata and resourceMetadata.

pdsRegistry

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. A required attribute of the pdsRegistry element named url, must be populated to specify the endpoint of the Registry Service. The following table describes the child elements that are allowed:

pdapServices

Specify this element to indicate the PDAP service endpoint for accessing product metadata for registration with the Registry Service. The following table describes the child elements that are allowed:

productMetadata

Specify this element to include additional metadata in the form of registry slots for every product. The following table describes the child elements that are allowed:

staticMetadata

Specify this element to include static metadata for every product. The following table describes the child elements that are allowed:

dynamicMetadata

Specify this element to include dynamic metadata for every product. The following table describes the child elements that are allowed:

resourceMetadata

Specify this element to include metadata for every resource product. A corresponding resource product is registered for every data set product registered. The following table describes the child elements that are allowed:

Report Format

This section describes the contents of the Harvest-PDAP Tool report. At this time, the tool only outputs a series of log messages. The log will report the success or failure of a discovered product attempting to be registered. 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:
