We are using Apache Maven to build koldfish-dam. The system has been tested under Linux, but should work with other os aswell. To use it, do the following:

1. Download the source code via github.
2. Execute the following command on your command line: mvn install
3. Include the following dependecy to your own maven project.

<dependency>
  <!-- Maven Data Acquisition Module-->
  <groupId>de.unikoblenz.west.koldfish</groupId>
  <artifactId>koldfish-dam</artifactId>
  <version>alpha1</version>
</dependency>

The concept of dam is completely message driven. Messages are sent between all components to realise The API consists of the following interfaces:

• Negotiator: is responsible to access the LOD cloud by
• Controller: requests an action, e.g. do dereference an URI, from a Negotiator and receives the answer.
• Accessor: gets activated by a Negotiator to answer a request and sends the answer back.
• Receiver: listenes to a Negotiator and gets notified if an Accessor returns an answer.

The communication between Controller - Negotiator - Accessor uses futures and the communicaton between Negotiator and Receiver is listener pattern based.
