Rosetta OpenWayback VPP

About

This plugin enables OpenWayback as an external viewer in Rosetta. It has two viewer modes:

• Overview (default): Directs users to the overview page for a given URL. This is similar to the user searching directly in OpenWayback.
• Detail: Directs users to a certain harvest represented by the requested IE.

Detail view mode needs a webserver redirect due to technical restrictions of Rosetta (see Installation for details).

The mode is selected by the viewer option detail. The value true selects detail mode, every other value (or none) selects overview mode.

Options

The VPP supports several options. To set an option, go in Rosetta Admin Backend to your delivery rule, section Output Parameters. Add an option using name=value.

Option	Value	Description
detail	true	Directs the user to the capture represented by the IE (URL at a certain harvest time).
	false	Directs the user to the overview page as if the user had searched for the URL in Wayback.
	default	false
marker	any	A string used to delimit the relevant URL in part for detail view for webserver redirects.
	default	@

Installation

Rosetta

1. Move the JAR-file to ./operational_shared/plugins/custom.
2. Rosetta Admin Backend: Go to Plugin-Management --> Custom Plugins and add a new Plugin Instance
3. Rosetta Admin Backend: Go to Delivery --> Viewers Management --> Add External Viewer:

• Level needs to be IE.
• URL needs to be http://<WAYBACK_HOSTNAME>/wayback/query

1. Rosetta Admin Backend: Go to Delivery --> IE Delivery Rules --> Add New Delivery Rule. At Output Parameters add detail=true for detail mode.

Apache Webserver

An example configuration for Apache Webserver. Only needed for detail mode. Same scheme would work with other webservers as well (fell free to contribute more configuration examples).

Development

To build this project the Rosetta PDS SDK from GitHub is needed as there is no public Maven repository. Note that the jar-Files for "deposit" and "plugin" are the same, but "deposit" has more Rosetta-Versions. To use the SDK, you have to download and install it locally:

curl -sS -O https://raw.githubusercontent.com/ExLibrisGroup/Rosetta.dps-sdk-projects/master/5.0.1/dps-sdk-deposit/lib/dps-sdk-5.0.1.jar
mvn install:install-file -Dfile=dps-sdk-5.0.1.jar -DgroupId=com.exlibris.dps -DartifactId=dps-sdk -Dversion=5.0.1 -Dpackaging=jar

Building a deployable jar file including all necessary configuration files:

mvn clean install
