5fc6524ca8 - moved triple store to net.yacy.cora.lod (should be generalized there
later
- added abstract add, delete, get methods in the triplestore
- added generation of triples after auto-annotation
- migrated all MultiProtocolURI objects to DigestURI in the parser since
the url hash is needed as subject value in the triples in the triple
store

659178942f - Redesigned crawler and parser to accept embedded links from the NOLOAD
queue and not from virtual documents generated by the parser.
- The parser now generates nice description texts for NOLOAD entries
which shall make it possible to find media content using the search
index and not using the media prefetch algorithm during search (which
was costly)
- Removed the media-search prefetch process from image search

49e5ca579f added new configuration property "crawler.embedLinksAsDocuments". If this is switched on (this is default now), the all embedded image, audio and video links from all parsed documents are added to the search index as individual document. This will increase the search index size dramatically but will also enable us to create a much faster image, audio and video search. If the flag is switched on, the index entries are also stored to a solr index, if this is also enabled.

0c1b29f3c9 - applied many small performance hacks
- added a memory limitation in the zip parser and the pdf parser
- added a search throttling: if there are too many search queries are still to be computed, then new requests are not accepted for some time. if after a one second still no space is there to perform another search, the search terminates with no results. this case should only happen in case of DoS-like situations and in case of strong load on a peer like if it is integrated in metager.
- added a search cache deletion process that removes search requests in case that throttling happens

b6fb239e74 redesign of parser interface:
some file types are containers for several files. These containers had been parsed in such a way that the set of resulting parsed content was merged into one single document before parsing. Using this parser infrastructure it is not possible to parse document containers that contain individual files. An example is a rss file where the rss messages can be treated as individual documents with their own url reference. Another example is a surrogate file which was treated with a special operation outside of the parser infrastructure.
This commit introduces a redesigned parser interface and a new abstract parser implementation. The new parser interface has now only one entry point and returns always a set of parsed documents. In case of single documents the parser method returns a set of one documents.
To be compliant with the new interface, the zip and tar parser had been also completely redesigned. All parsers are now much more simple and cleaner in its structure. The switchboard operations had been extended to operate with sets of parsed files, not single parsed files.
additionally, parsing of jar manifest files had been added.

37b8827a7a - removed the UPnP library sources from sbbi and added the jar library again. The library was included to get support for fedora releases, but after this time the fact that the sbbi cannot be part of fedora should be re-discussed. If this will still not be possible, then we may integrate the sbbi UPnP package using reflection.
- cleaned uo the code. The new eclipse helios provided new warnings for dead code. This change cleans up most of these warnings

11639aef35 - added new protocol loader for 'file'-type URLs
- it is now possible to crawl the local file system with an intranet peer
- redesign of URL handling
- refactoring: created LGPLed package cora: 'content retrieval api' which may be used externally by other applications without yacy core elements because it has no dependencies to other parts of yacy
