JavaScript Code

 _IG_FetchXmlContent("http://www.myexperiment.org/workflow.xml?id=59&all_elements=yes", function(response) {
   // the iGoogle Fetch XML Content function takes 2 parameters, a url and an anonymous "onResponse" function
   // the onResponse function is called with a single parameter, shown here as the "response" object
   if (response == null || typeof(response) != "object" || response.firstChild == null) {
     return;
   } // after testing for errors, the response must be "<workflow> ... </workflow>"
   
   var uri = response.getAttribute("uri");
   var resource = response.getAttribute("resource");
   var version = response.getAttribute("version");
   
   for (var i = 0; i < response.childNodes.length; ++i) { // iterate over child nodes
     var node = response.childNodes.item(i);
     if (node.nodeName == "title") { // do something with the workflow title...
       var title = node.nodeValue;
     }      
   } // ...parse other child nodes
   
   // do something with the response
 });

Workflows Feed Reader

This Google Gadget is a customisable Feed Reader that uses the myExperiment Workflows feed [1] and the workflows index REST function [2] provided by the myExperiment REST API. The screen-shot on the right was produced using the following REST function call:

 http://www.myexperiment.org/workflows.xml?num=20&page=1&sort=updated&order=reverse

The workflows index function has five optional parameters:

• num and page are used for pagination of results
• sort the results by title, created, updated (or name for objects with a name attribute!)
• results can be returned in reverse order
• tag is used to obtain tagged objects

The workflows index function returns an ordered list of <workflow> elements:

 <workflows>
   <workflow uri="http://www.myexperiment.org/workflow.xml?id=337" resource="...">
     Download from ChemSpider using Accurate Mass
   </workflow>
   <workflow uri="http://www.myexperiment.org/workflow.xml?id=59" resource="...">
     QR code (matrix code) generator
   </workflow>
   ... 
 </workflows>

Tag Cloud

This Google Gadget is a customisable Tag Cloud that uses the myExperiment REST API. The screen-shot on the right was produced using the following REST function call:

 http://www.myexperiment.org/tag-cloud.xml?num=all

The tag cloud function has one optional parameter:

• num specifies the number of tags in the tag cloud (or all for a complete cloud)
• type specifies the allowed object types (workflow, file, group or user)

The tag cloud function returns an list of <tag> elements, ordered by name:

 <tag-cloud type="all">
   <tag uri="http://www.myexperiment.org/tag.xml?id=547" resource="..." count="2">
     abstracts
   </tag>
   <tag uri="http://www.myexperiment.org/tag.xml?id=559" resource="..." count="1">
     access grid
   </tag>
   <tag uri="http://www.myexperiment.org/tag.xml?id=642" resource="..." count="3">
     accurate mass
   </tag>
   ...
 </tag-cloud>
