Asset collection query placeholders

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

The standard query definitions for the dynamic asset collections contain a placeholder for a section path. Is there any documentation available on what other placeholders could be used here? Or could you point me to the location in the code where these placeholders are processed?

There are a couple of others provided: "siteid" and "sectionid".

However, as you might hope, this is a pluggable component, so you can add in as many more as you want. If you take a look in the file "context-parsers-context.xml" you will see all the provided placeholder processors (they are called "context parsers") along with an abstract bean definition named "wcmquickstartmodule_contextParser". To plug-in a new context parser, create a new class that extends the abstract class "org.alfresco.module.org_alfresco_module_wcmquickstart.util.contextparser.ContextParser" and register a bean for it using the abstract "wcmquickstartmodule_contextParser" bean as its parent.

To take the "section" parser as an example, this is defined by the class "SectionPathContextParser" and the bean "wcmquickstartmodule_sectionPathContextParser". The bean definition looks like this:

    <bean id="wcmquickstartmodule_sectionPathContextParser"
          parent="wcmquickstartmodule_contextParser"
          class="org.alfresco.module.org_alfresco_module_wcmquickstart.util.contextparser.SectionPathContextParser">
        <property name="name" value="section" />
    </bean>

Note the reference to the parent bean: "wcmquickstartmodule_contextParser". Also note the value of the name property of this bean: "section" - by default this is used as the key that ties your parser to a particular placeholder (although this is overridden by this particular parser).

Hopefully that makes sense and gives you the starting point you need. Come back to me if you need more information.
