You can import Wikipedia dumps here. An example is the file
|
|
|
|
|
<a href="http://download.wikimedia.org/dewiki/20090311/dewiki-20090311-pages-articles.xml.bz2">
|
|
|
|
|
http://download.wikimedia.org/dewiki/20090311/dewiki-20090311-pages-articles.xml.bz2</a>.
|
|
|
|
|
<br />
|
|
|
|
|
Dumps must be in XML format and must be encoded in bz2. Do not decompress the file after downloading!
|
|
|
|
|
<br />
|
|
|
|
|
<input name="file" type="text" value="DATA/HTCACHE/dewiki-20090311-pages-articles.xml.bz2" size="80" />
|
|
|
|
|
<input name="submit" type="submit" value="Import Wikimedia Dump" />

When the import is started, the following happens:
|
|
|
|
|
</p><ul>
|
|
|
|
|
<li>The dump is extracted on the fly and wiki entries are translated into Dublin Core data format. The output looks like this:

</li>
|
|
|
|
|
<li>Each 10000 wiki records are combined in one output file which is written to /DATA/SURROGATES/in into a temporary file.</li>
|
|
|
|
|
<li>When each of the generated output file is finished, it is renamed to a .xml file</li>
|
|
|
|
|
<li>Each time a xml surrogate file appears in /DATA/SURROGATES/in, the YaCy indexer fetches the file and indexes the record entries.</li>
|
|
|
|
|
<li>When a surrogate file is finished with indexing, it is moved to /DATA/SURROGATES/out</li>
|
|
|
|
|
<li>You can recycle processed surrogate files by moving them from /DATA/SURROGATES/out to /DATA/SURROGATES/in</li>
