Content

Content is the project which provides the 'Resources' tool in Sakai.

Copyright Options within the 'Resources' tool in Sakai

When uploading files to the 'Resources' tool, Sakai can offer or require that users consider the copyright of the files they are uploading.

Out of the box, Sakai provides six default copyright options to be selected for files uploaded to the 'Resources' tool:

  1. "Material is in public domain." (public_domain)
  2. "I hold copyright." (hold_copyright)
  3. "I have obtained permission to use this material." (have_permission)
  4. "Copyright status is not yet determined." (not_determined)
  5. "Use copyright below." (use_below)
  6. "Material is subject to fair use exception." (fair_use)

For more information on configuring this feature, such as defining the default copyright selection, requiring explicit selection of a copyright selection, defining a custom list of copyright options and setting up documentation around copyright options (default or custom), please see the README.md located at:

Release Notes

Sakai 10.0

SAK-25371 - The feature will add "Print File" action option to the Resources tool for those print-eligible-type resource items. The printing will be done on item-by-item base, not with a batch mode. The feature will save user effort of downloading the resource first and then upload to a server.

The following is required to enable the "Print File" choice in the Resources tool:

  1. Implement org.sakaiproject.content.api.ContentPrintService
  2. Configure implementation in your provider's components.xml
    • You'll need to first comment out the default implementation in the kernel (kernel-component/src/main/webapp/WEB-INF/content-components.xml), and then configure your provider
    • This is an example of UM's provider implementation:
<beans>
	<bean id="org.sakaiproject.content.api.ContentPrintService"
		class="org.sakaiproject.content.impl.ContentPrintServiceUnivOfMichImpl"
		singleton="true">
	</bean>
</beans>
  1. Define print_server_url in your sakai.properties
  2. An example provider implementation is available at https://source.sakaiproject.org/svn//msub/umich.edu/ctools/ctools-providers/branches/2.9.x-from-2.7.x/contentprint/

Sakai 2.5

The following steps are required to run the conversion from 2.4 to 2.5 database schema for content (ContentHostingService) to improve performance of the Resources tool and other tools that depend on it. Unless otherwise indicated, all files referred to are in the root directory of the content project. These instructions apply to MySQL or Oracle. If a different database is used, a new version of the config file will be needed.

A shell script named "content-runconversion.sh" is used to perform the conversion. Although you don't necessarily have to edit it, you will need to do at least one Sakai build in order to populate your local Maven repository cache with the required library JAR files. The standard "runconversion.sh" shell script is needed, and expected to be at:

../db/db-util/conversion/runconversion.sh

If you want to move that script to another location, or if you want to specify different locations for the JAR files, you'll have to edit the scripts.

Otherwise, you can use the scripts as they are by specifying a JDBC driver JAR, a source of database properties, and an input "config" file on the command line.

A typical full conversion for an Oracle site on Linux might be:

   nohup ./content-runconversion.sh \
      -j "$CATALINA_HOME/shared/lib/ojdbc14.jar" \
      -p "$CATALINA_HOME/sakai/sakai.properties" \
      upgradeschema-oracle.config &> ~/content-runconversion.log &

A typical full conversion for a MySQL site might be:

   nohup ./content-runconversion.sh \
      -j "$CATALINA_HOME/shared/lib/mysql-connector-java-5.1.5.jar" \
      -p "$CATALINA_HOME/sakai/sakai.properties" \
      upgradeschema-mysql.config &> ~/content-runconversion.log &

For a large site, the script will likely run for many hours, and so we recommend that you use no-hangup mode and save all output to a log file.

You may see warnings about records with a null source. These are almost certainly harmless, and may reflect records that have been created or updated since your move to the new version of Sakai software.

If you need to interrupt the migration, copy or create a file named "quit.txt" in the working directory. You can start from where you left off by deleting the "quit.txt" file and beginning over. Similarly, if the procedure is interrupted by an error, you should be able to start safely from where you left off (although you should read the last paragraph if the interruption occurred during the second phase of the migration).

Because the procedure is time-consuming, you might prefer to do the conversion in two phases. To do so, first comment out the "convert.1" lines in the config script. After the "Type1BlobResourceConversion" process is finished, you can then comment out the "convert.0" lines, uncomment the "convert.1" lines, change them to "convert.0", and run again. In particular, you'll want to do this if the process has been interrupted after the first phase is complete. Otherwise, the first phase will start (unnecessarily) over again from the beginning.
