    v1 v1  
     1<h1>Semantic Data Access by Aduna &amp; DFKI <br> 
     2</h1> 
     3To extract data and fulltext from various datasources and store them in 
     4systems like gnowsis or Aduna Metadata Server.<br> 
     5<h2>Sourceforge Project</h2> 
     6Administrators: Christiaan Fluit &amp; Leo Sauermann<br> 
     7Source Code: Interfaces and standard implementations of the SeDAF<br> 
     8<br> 
     9The source will contain all relevant information about semantic data 
     10extraction, everything that is needed to get starting with a fulltext 
     11and metadata extraction framework. Our intent is that developers can 
     12download a single distribution file with a fully working environment, 
     13that also includes adapter and extractor implementations. Developers 
     14can use this package to fill their lucene-based applications or other 
     15data stores.<br> 
     16<br> 
     17The features of the framework will be:<br> 
     18<ul> 
     19  <li>easy to use: easy to learn, easy to code, easy to deploy in 
     20industrial projects<br> 
     21  </li> 
     22  <li>Extract fulltext from many common file formats and information 
     23systems like IMAP email servers</li> 
     24  <li>Extract metadata like author, date, subject and more from the 
     25data sources</li> 
     26  <li>open the data objects for viewing<br> 
     27  </li> 
     28  <li>Fully configurable framework, storing and editing config files is 
     29done through a SWING gui.</li> 
     30  <li>Pluggable architecture: can be easily extended, can be easily 
     31integrated to other projects. <br> 
     32  </li> 
     33  <li>Architecture based on industry standard OSGI</li> 
     34  <li>Compatible with RDF, but not solely based on it</li> 
     35</ul> 
     36Components in the framework are:<br> 
     37<ul> 
     38  <li>DataSource Interface</li> 
     39  <li>TextExtractor Interface</li> 
     40  <li>DataSource implementation for Filesystem</li> 
     41  <li>DataSource implementation for IMAP mail servers</li> 
     42  <li>TextExtractor implementation for everything we know: PDF, Word, 
     43Fulltext, excel</li> 
     44  <li>OSGI bindings and connector code<br> 
     45  </li> 
     46  <li>Configuration gui</li> 
     47  <li>Sample appication showing how to use it, with gui (=either 
     48Autofocus or Sesame or Gnowsis)</li> 
     49  <li>Metadata format description (RDFS schema) and example file for 
     50the metadata<br> 
     51  </li> 
     52</ul> 
     53Right from the beginning we will support the following file types:<br>
