Brown Dog - Adding Tools to the DAP and DTS, Overview and Examples

Introduction

This guide is intended as an introduction for new users working with the Brown Dog software platform. An introduction to the 3 main components of the platform, Polyglot, Medici, and Versus will be presented, and examples of scripts and code are provided. These 3 tools can be leveraged to add tools to the Data Access Proxy (DAP) and Data Tilling Service (DTS).

Prerequisites

This overview assumes a basic level of knowledge about the three main components of the Brown Dog software platform, Polyglot, Medici, and Versus. Some background information will be provided, however, for a more in depth overview of each of these components and their function, it is recommended that you take the opportunity to view the provided online tutorial sessions that may be found on the ISDA's YouTube account: http://www.youtube.com/channel/UCGIXAeNEa2v7Gt-tvfdJPvw.

Example Extractors

Java

Connecting to RabbitMQ

protected void startExtractor(String rabbitMQUsername,
	String rabbitMQpassword) {
	try{ 
 		//Open channel and declare exchange and consumer
		ConnectionFactory factory = new ConnectionFactory();
		factory.setHost(serverAddr);

		Connection connection = factory.newConnection();

 		final Channel channel = connection.createChannel();
		channel.exchangeDeclare(EXCHANGE_NAME, "topic", true);

		channel.queueDeclare(QUEUE_NAME,DURABLE,EXCLUSIVE,AUTO_DELETE,null);
		channel.queueBind(QUEUE_NAME, EXCHANGE_NAME, "*.file.text.plain.#");
 
 		this.channel = channel;

 		// create listener
		channel.basicConsume(QUEUE_NAME, false, CONSUMER_TAG, new DefaultConsumer(channel) {
 			@Override
 			public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
				messageReceived = new String(body);

Instantiating the logger and starting the extractor

def main():
 global logger

 # name of receiver
receiver='ExamplePythonExtractor'

 # configure the logging system
logging.basicConfig(format="%(asctime)-15s %(name)-10s %(levelname)-7s : %(message)s", level=logging.WARN)
logger = logging.getLogger(receiver)
logger.setLevel(logging.DEBUG)
 
 if len(sys.argv) != 4:
logger.info("Input RabbitMQ username, followed by RabbitMQ password and Medici REST API key.")
sys.exit()
 
 global playserverKey
playserverKey = sys.argv[3]

Connecting to RabbitMQ

# connect to rabbitmq using input username and password 
credentials = pika.PlainCredentials(sys.argv[1], sys.argv[2])
parameters = pika.ConnectionParameters(credentials=credentials)
connection = pika.BlockingConnection(parameters)
 
 # connect to channel
channel = connection.channel()

 # declare the exchange
channel.exchange_declare(exchange='medici', exchange_type='topic', durable=True)

 # declare the queue
channel.queue_declare(queue=receiver, durable=True)

 # connect queue and exchange
channel.queue_bind(queue=receiver, exchange='medici', routing_key='*.file.text.plain')

 # create listener
channel.basic_consume(on_message, queue=receiver, no_ack=False)

 # start listening

 try:

Measure

public class WordCountMeasure implements Serializable,Measure {

	private static final long SLEEP = 10000;
