= Moving to catwiesel =

project gnowsis-server is needed alone! (has junit tests)

change fulltext search
 * Storage: refactor interface org.gnowsis.repository.ResourceStorage to include access to "catwiesel"\
 * change the impl of ResourceStorageImpl to have catwiesel as private variable
 * remove LuceneSailAperture from ResourceStorageImpl, replace it with normal Sesame2 Sail
 * implement fulltext search of interface ResourceStorageImpl
 * implement addResource() and removeResource() of ResourceStorageImpl
 * all metadata is stored still in the normal Sesame2 sail.
 * see that some core metadata are lucene searchable: look at LuceneSailAperture to find out which

change synchroniser - performance question
 * look at  source:branches/gnowsis0.9/gnowsis-server/src/java/org/gnowsis/data/impl/ApertureSynchroniserImpl.java
 * look at source:branches/gnowsis0.9/gnowsis-server/src/java/org/gnowsis/data/impl/GnowsisCrawlerHandler.java
 * crawler handler calls ResourceStorage.addResource() - you don't have to change aperture\
 * todo: apertureSynchroniser: before it starts tell catwiesel to stop updating categories
 * after crawl finished, tell catwiesel to update  categories.
