Change Ambra information model classes to utilize new features in Topaz.

[amit]

Topaz has added a string of useful concepts such as 'views', '@Blob', etc. that would make the application logic in Ambra simpler. Specifically:

• blob management via @Blob
• use @View in place of hand-coded views

Added dependency

[pradeep]

(In [5429]) Use @Blob for annotations and replies. Addresses #856.

[pradeep]

(In [5475]) Convert ObjectInfo? representations to use the Blob support available from OTM. This required a bit of data-migration (to get rid of the ugly format-contentType and format-objectSize dynamic predicates and to have topaz:hasRepresentation point to the Representation object as opposed to a literal value).

To have minimum impact on the ongoing development effort, this migration is done automatically at stratup by ambra. It can be used in production also, but if required can be turned off by removing this listener from web.xml.

Also note that there is no change done to ingest. Usage of otm-models and the blob will be done as part of #439. Till then the data-migration is done automatically as a post-processing of ingest.

This addresses #776 and #856. (RepresentationInfo? is now gone)

[pradeep]

(In [5485]) Convert ArticleInfo? and RelatedArticleInfo? to OTM Views. Also moved the 'usage' classes CitationInfo? and UserProfileInfo? to outside the BrowseService?.

Addresses #856 and #776.

[pradeep]

(In [5501]) Convert NewArtInfo? in browse service to an OTM view.

Addresses #856.

[pradeep]

There are no more candidates for conversion to Views at this time. So closing this ticket.

Note that ingest is currently still going directly to Fedora for blobs and mulgara for RDF. #439 will fix that and move things over to OTM.
