- vocabulary annotation is not done any more into the metadata of urldb
- vocabularies are written into the jena triplestore using a rdf
vocabulary
- vocabularies for rdf tripel must be updated; refactoring done
- with the new navigation tags in the triplestore a faster
pre-urldb-lookup is possible: navigation is processed now within the RWI
during pre-ranking retrieval
- added also a Owl vocabulary stub to add the plain-text url to the
triplestore using the owl:sameas predicate
- added log warnings in case that search processes run into time-out
situations
- better concurrency for Integer formatter (used a non-synchronized
formatter before)
- bugfix for search termination (a poison pill was missing)
- added timeout parameters for search (again) -> target is, that they
are never reached.
- search request are now made using a map boundary
- search results are only computed for the map boundary
- the number of results is adopted to the results in the visible range
- added a double-buffering for the search result markers
- added a search query option for the search results:
/radius/<lat>/<lon>/<radius>
- a new database for url reference data ('seen links')
- a new database extending the references to the full url metadata
attributes set which shall replace the old metadata database if it is
finished
- migration help classes stub to use old and new metadata databases

See

and the following test programm:
public class QueueLengthTimeTest {
public static long countTest(Queue<Integer> q, int c) {
long t = System.currentTimeMillis();
for (int i = 0; i < c; i++) {
q.add(q.size());
}
return System.currentTimeMillis() - t;
}
public static void main(String[] args) {
int c = 1;
for (int i = 0; i < 100; i++) {
Runtime.getRuntime().gc();
long t1 = countTest(new ArrayBlockingQueue<Integer>(c), c);
Runtime.getRuntime().gc();
long t2 = countTest(new LinkedBlockingQueue<Integer>(), c);
Runtime.getRuntime().gc();
long t3 = countTest(new ConcurrentLinkedQueue<Integer>(),
c);
System.out.println("count = " + c + ": ArrayBlockingQueue =
" + t1 + ", LinkedBlockingQueue = " + t2 + ", ConcurrentLinkedQueue = "
+ t3);
c = c * 2;
}
}
}

The search can now be configured with a non-display host list.
the search will always exlude the given list of host unless they are
requested directly using the host navigation
