On the other hand, @Mire has prototyped a Solr driven Authority Control capable of caching and mixing together authority sources so that they can utilized for super fast term completion and lookup. Solr is quite effective for quickly retrieving lists of values that a field should be restricted to. Likewise, when the original DSpace metadata is indexed into the Solr based authority control, the Submitter is also presented with an ad-hoc authority of existing values already contained within the repository. In similar way, the project Hive from NESCent provides (a SILS Metadata Research Center/NESCent collaboration) provides both SPARQL based semantic querying and Lucene indexing based keyword searching for Authority Control concepts in SKOS (RDF/XML) format. The success of project Hive has proved the feasibility of this GSoC 2011 project. Therefore I propose to use DSpace TupeloStorageService for SKOS Authority Control storage and SPARQL/Solr for fast term completion and lookup in existing Authority Controls.
