switchboard web services library
Apr 23^rd, 2006, 7:01am

Hello everyone,

I'd like to introduce my Processing library, Switchboard. The goal of Switchboard is to be a simple interface to as many web and network-related functions as possible, and to simplify the creation of projects that use several data sources. Currently, I have implemented 22 "services" (some more solid than others), including google, yahoo, msn, allmusic, shoutcast, foaf, and rss/atom feeds. There are many more services planned, which can be found in the "to-do" section of the site. Switchboard also includes utilities for screen scraping, including XQuery and Lucene text search. The interface uses a simple callback method, similar to other Processing libraries with asynchronous elements.

I am just a little protective of Switchboard at the moment because there are still some semi-major bugs that I haven't had time to fix. It is definitely usable, but I am posting it here mostly in the hope that some of you might want to help me sort out these bugs and/or add new features. Underneath the interface is an extensible framework which is build on Apache Axis (among other packages), so it is pretty easy to add any service with a WSDL file. I could also use help creating example code in the documentation.

If you have any questions or suggestions, please let me know.

Hi there,

switchboard seems to be a really nice library and is exactly what I need right now. The problem is that, after following the installation steps, the following code won't execute.

import org.switchboard.*;

Switchboard board;

void setup() {

// The switchboard will be our interface to all of the services.

board = new Switchboard(this);
}

// this method will be called whenever we get a result from any of our services.
void resultReceived() {
}

The error message is:

endOfResults() was not found in class Temporary_1221_8474
You will not be notified when a service is finished.
status() was not found in class Temporary_1221_8474

-----------

I use processing 115 on linux.

Any suggestions?

I looked at the code of switchboard and figured out that

----------
endOfResults() was not found in class Temporary_1221_8474
You will not be notified when a service is finished.
status() was not found in class Temporary_1221_8474
----------

are only warnings which appear when certain methods are not implemented in the processing code. Maybe this could be indicated in future.

has anyone any experiences with the FOAF service..? i can not get it to work, even this simplified demo from jeff. prog just hangs..
what does the level number mean after the URL, bytheway?
thanks for reply.

import org.switchboard.*;

Switchboard board;

void setup() {

size(400, 400);

framerate(10);

background(20, 40, 60);

board = new Switchboard(this);

board.foaf("http://rdfweb.org/people/danbri/rdfweb/danbri-foaf.rdf", 2);

}

void resultReceived() {

if(board.resultService == Switchboard.FOAF) {

print(board.foaf.getName());

}
}

public void draw() {

}

Hi all,

I was hoping someone might be able to point me in the right direction...

what API key should I be downloading from Google to use with the Switchboard Library? I have the "Base API", which doesn't seem to be returning anything...

is this the right Google API?
Code:


import org.switchboard.*;

Switchboard board;

void setup() {
  board = new Switchboard(this);
  board.setGoogleKey("----here is where I'm pasting my Google Base API key---------");
  board.google("Hungry Hungry Hippo");
}

void resultReceived() {
  println("anything?");
  println(board.google.getURL());
}

this gives me nothing... (same as if I put a deliberately wrong key in)

any help, HUGEly appreciated

THANKS

C

I signed up for google base data api http://code.google.com/apis/base/signup.html but it doesn't work with that key. Does anyone have a solution for that problem?

Google Base is some weird thing that from what I can tell, has pretty much nothing to do with anything :/ -C

marion YaBB Newbies Offline Posts: 3	Re: switchboard web services library Reply #8 - Dec 5^th, 2006, 3:59pm Hello I use switchboard to get results of webservices, especially from amazon and google. I have problems with the number of results. There are only 10 results given back. Is it possible to change the number of results or to get more results, about 100? Does anybody have a solution for this problem?

Inspired by the semi-evil decision by Google to discontinue support for their SOAP search API, I started a ground-up rewrite of Switchboard with a much leaner code base, better functionality, and lots more features. Having already had one go at it, this version will be much cleaner and easier to use and maintain. I have been working on it on and off for a few weeks now, but I would love (and desperately need) some help if anyone is interested.

If you are interested, please send me a message on this board and we can discuss how this will work. I am not longer working on the SourceForge SVN, so don't even bother looking on there. Thanks guys.

That's not one error message, but several warning messages, quite explicit.
I believe they say you need to implement the mentioned functions if you want to get significant results/notifications in your sketch.
These functions are so-called call-back functions, ie. you provide them, and the library calls them when an event occurs: service returns a result, service is finished, library provides status messages, etc.
