8.3.2 Example

Here is an example query expressed as XML, to be submitted via the HTTP API:

<?xml version="1.0"?>
<query xmlns="http://outerx.org/daisy/1.0#workflow">

  <selectClause>
    <select name="process.id" type="property"/>
    <select name="process.definitionLabel" type="property"/>
    <select name="daisy_description" type="process_variable"/>
  </selectClause>

  <conditions meetAllCriteria="true">
    <propertyCondition name="process.end"
                       operator="is_null"
                       valueType="datetime"/>
  </conditions>

  <orderByClause>
    <orderBy name="process.id" type="property" sortOrder="descending"/>
  </orderByClause>

</query>

You can try it out using a tool such as wget. Save the query to a file (e.g. querytest.xml), and then post it to the repository using:

wget --post-file="querytest.xml"
     --http-user=testuser
     --http-password=testuser
     --header="Content-Type: text/xml"
     "http://localhost:9263/workflow/query/process?locale=en-US"

(everything should be on one line, adjust username, password, repository URL as necessary)
