This documentation is still in progress and 3.3 has not been released yet.

Validating Media Object metadata

Avalon release 3.3 includes a new requirement that metadata values Creation Date, Copyright Date and Date Issued conform to the Extended Date Time Format. Dates that do not conform will not be indexed and therefore will not be searchable. To assisting in identifying existing records affected by this change, a tool has been implemented to identify those records. In addition to identifying invalid dates it identifies all records with ANY invalid metadata. Run the tool by executing the following command:

$ su - avalon -c "cd /var/www/avalon/current; RAILS_ENV='production' bundle exec rake avalon:validate"

Any records identified as having validation errors should be fixed so that they will be indexed. After fixing those records, reindex by running the following:

$ su - avalon -c "cd /var/www/avalon/current; RAILS_ENV='production' bundle exec rake avalon:reindex"

Matterhorn

Workflow updates to support multiple derivative batch ingest

Part of the changes made to get multiple derivatives ingest to work was adding new Matterhorn workflows.  Here are the raws for the three files you'll want to replace in mattherhorn/etc/workflows:

avalon-skip-transcoding.xml
avalon-skip-transcoding-audio.xml
default-error-handler.xml

Matterhorn disk cleanup

In previous Avalon versions, there was a potential for Matterhorn disk space to fill with workflow artifacts. The default error handler workflow updated as above reduces this potential significantly. And a tool is provided in Release 3.3 that helps clean up Matterhorn workspace further. More can be learned here.
