=== Check out and build the source code ===

<pre>
$ git clone git://gitorious.org/discovered/repo.git discovered
$ cd discovered
$ ant
</pre>

=== Add a curator and a feed ===

DiscoverEd uses feeds to help identify resources to crawl.  Feeds are provided by curators, who can also provide metadata about resources.

<pre>
$ ./bin/feeds addcurator "ND OCW" http://ocw.nd.edu/ 
$ ./bin/feeds addfeed rss http://ocw.nd.edu/front-page/courselist/rss http://ocw.nd.edu/
</pre>

=== Aggregate and crawl resources ===

<pre>
$ ./bin/feeds aggregate
$ mkdir seed
$ ./bin/feeds seed > seed/urls.txt
$ ant -f dedbuild.xml crawl
</pre>

=== Run the web application ===

Edit conf/nutch-site.xml to point to your crawl location.

<pre>
$ ant war
$ [copy the war file to your J2EE container]
</pre>

=== Switching to MySQL ===

By default, DiscoverEd (at least on the ''next'' branch) uses an on-disk database called Derby for storing resource metadata. You should use a different database, like MySQL, in production.

To do that, edit '''conf/discovered.xml''' and update the following sections as appropriate:

<pre>
<property>
  <name>rdfstore.db.driver</name>
  <value>com.mysql.jdbc.Driver</value>
</property>

<property>
  <name>rdfstore.db.url</name>
  <value>jdbc:mysql://localhost/discovered?autoReconnect=true</value>
</property>

<property>
  <name>rdfstore.db.user</name>
  <value>discovered</value>
</property>

<property>
  <name>rdfstore.db.password</name>
  <value></value>
</property>

</pre>

== Known issues ==

=== Derby and OAI:PMH aren't compatible ===

If you use the default backend, OAI:PMH crawls won't work. Instead, you'll get SQL syntax errors from the code. We haven't fully diagnosed the problem; instead, if you get a problem like that, we suggest you switch to MySQL as per the "Switching to MySQL" section.
