The <resourceid> element provides an identifier for applications that must use their own identifier scheme, such as context-sensitive help systems and databases.

The @appid and @appname attributes are available to associate an ID with an application. Multiple @appid values can be associated with a single @appname value, and multiple @appname values can be associated with a single @appid value. Because the values for the @appid and @appname attributes work in combination to specify a specific ID for a specific application, each combination of values for the @appid and @appname attributes should be unique within the context of a single root map.

Versions of DITA before 1.3 used the @id attribute on the <resourceid> element to specify an ID for an external application. Beginning with DITA 1.3, this use of the @id attribute is deprecated in favor of using the @appid attribute.

- topic/resourceid


In the following example, user-assistance context hooks are applied to three topics that are referenced from a DITA map. The second topic has two hooks for the same topic.

<map title="Widget Help">
 <topicref href="file_ops.dita" type="concept">
   <topicref href="saving.dita" type="task">
     <resourceid appname="ua" appid="1234" ux-context-string="idh_filesave"
     ux-source-priority="topic-only" />
   <topicref href="deleting.dita" type="task">
      <resourceid appname="ua" 
           appid="2345" ux-context-string="idh_filedelete" />
      <resourceid appname="ua" 
           appid="6789" ux-context-string="idh_filekill" />
   <topicref href="editing.dita" type="task">
       <resourceid appname="ua" 
            appid="5432" ux-context-string="idh_fileedit" ux-windowref="csh"  />

In the following example, a user-assistance context hook is defined in the prolog of a task topic. The context hook is made up of a context ID (value for @appid attribute) and a context string (value for @ux-context-string attribute). A user-assistance window profile also is referenced for this topic.

<task id="fedt">
 <title>Editing a File</title>
   <resourceid appname="ua" 
         appid="5432" ux-context-string="idh_fileedit" ux-windowref="csh" />
  <context>After you have created a new file, you can edit it.</context> 


The following attributes are available on this element: Universal attribute group (with a narrowed definition of @id, given below) and the attributes defined below.

Before DITA 1.3, this attribute specified a value that was used by a specific application to identify the topic. That usage is deprecated in favor of using the @appid attribute. This attribute is defined with the XML Data Type CDATA.
A name for the external application that references the topic.
An ID used by an application to identify the topic.
Contains the value of a user-assistance context-string that is used to identify the topic.
Specifies precedence for handling <resourceid> definitions that exist in both a map and a topic. This attribute only is valid when used within a <topicref> element in a map. The allowable values are -dita-use-conref-target and the following:
Use IDs from both the topic and map.
Use IDs from the topic only.
Use IDs from the map only.
Use the IDs from the map (if they exist); otherwise, use IDs from the topic.
Use the IDs from the topic (if they exist); otherwise, use IDs from the map.
References the @name attribute on the <ux-window> element that is used to display the topic when called from a help API.
