unable to order volumes withing a journal

Requires an update to the volume/issue models and corresponding data migration. Moving to 0.9.3

We pitched that feature.

Enhancement request - removing from 0.9.3

From looking at the code they have never been able to order the volumes. Yes the field was available but in order for reordering to happen:

File: Journal.java

  @Predicate(uri = "plos:Journal/volumes")
  public void setVolumes(List<URI> volumes) {
    this.volumes= volumes;
  }

would need to be changed to

 @Predicate(uri = "plos:Journal/volumes", collectionType = CollectionType.RDFSEQ)
 public void setVolumes(List<URI> volumes) {
    this.volumes= volumes;

which will require a migration.
