ApertureSynchroniser

A service responsible for updating the ResourceStorage by crawling datasources using Aperture.

From the user interface aspect, a progress bar/indicator would be good to have while crawling a datasource.

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:trunk/gnowsis-server/src/java/org/gnowsis/data/impl/ApertureSynchroniserImpl.java
• look at source:trunk/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.
