Hi David,
I'm curious, why use 2 pipelines? Each will be tied to a specific xquery module/function. Why not combine the modules/functions into one and have just one pipeline? You be able to track the status of the first module to determine if the second should be executed.

This file contains a list of document Ids, something like: <items> <item>doc1.xml</item> <item>doc2.xml</item> ... </items> The following pipeline executes 'q1.xqy' which iterates through these documents and does something for each file: <?xml-stylesheet href="/cpf/pipelines.css" type="text/css"?> <pipeline xsi:schemaLocation="http://marklogic.com/cpf/pipelines pipelines.xsd <http://marklogic.com/cpf/pipelines%20pipelines.xsd> " xmlns="http://marklogic.com/cpf/pipelines"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <pipeline-name>Query1</pipeline-name> <success-action> <module>/MarkLogic/cpf/actions/success-action.xqy</module> </success-action> <failure-action> <module>/MarkLogic/cpf/actions/failure-action.xqy</module> </failure-action> <state-transition> <state>http://marklogic.com/states/initial <http://marklogic.com/states/initial%3c/state> </state> <on-success>http://marklogic.com/states/intermediate <http://marklogic.com/states/intermediate%3c/on-success> </on-success> <on-failure>http://marklogic.com/states/error <http://marklogic.com/states/error%3c/on-failure> </on-failure> <execute> <condition> <module>/MarkLogic/cpf/actions/namespace-condition.xqy</module> <options xmlns="/MarkLogic/cpf/actions/namespace-condition.xqy"> <root-element>items</root-element> <namespace/> </options> </condition> <action> <module>q1.xqy</module> </action> </execute> </state-transition> </pipeline> This part works fine. I now have a second pipeline, called q2.xqy, which I want to execute only after q1.xqy has completed. It looks like: <?xml-stylesheet href="/cpf/pipelines.css" type="text/css"?> <pipeline xsi:schemaLocation="http://marklogic.com/cpf/pipelines pipelines.xsd <http://marklogic.com/cpf/pipelines%20pipelines.xsd> " xmlns="http://marklogic.com/cpf/pipelines"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <pipeline-name>Query 2</pipeline-name> <success-action> <module>/MarkLogic/cpf/actions/success-action.xqy</module> </success-action> <failure-action> <module>/MarkLogic/cpf/actions/failure-action.xqy</module> </failure-action> <state-transition> <state>http://marklogic.com/states/intermediate <http://marklogic.com/states/intermediate%3c/state> </state> <on-success>http://marklogic.com/states/updated <http://marklogic.com/states/updated%3c/on-success> </on-success> <on-failure>http://marklogic.com/states/error <http://marklogic.com/states/error%3c/on-failure> </on-failure> <execute> <condition> <module>/MarkLogic/cpf/actions/namespace-condition.xqy</module> <options xmlns="/MarkLogic/cpf/actions/namespace-condition.xqy"> <root-element>items</root-element> <namespace/> </options> </condition> <action> <module>q2.xqy</module> </action> </execute> </state-transition> </pipeline> Note it has the same condition as the first query, since the file it acts on has not changed. I am trying to use state transitions to manage the order in which each pipeline is executed. So the first pipeline should set the state to 'intermediate' at which point the second pipeline should be executed and finally set the state to updated. Currently, the second pipeline does run, but the state never moves to 'updated'. I'm not sure this is even what I want, since I need the second pipeline to wait for the first one to complete. Does the state change immediately or wait until the query completes? If the former, then perhaps I should be using processing status rather than state? How do I create a second pipeline that only runs after the first one completes?
