XML Metadata Extractor configuration problem

Hi, I've run through the wiki article on this, but can't seem to get it to run.  I've imported a number of XMLs with the following DOM:

<Recipe>
    <Title>Value1</Title>
    <Author>Value2</Author>
    <Instruction>Value3</Instruction>
    <… />
</Recipe>‍‍‍‍‍‍

And I want to take the Title, Author and Instruction values and insert them into the Title, Author and Description fields on a basic Alfresco document.

I've configured my extractor with a selector to target just the Recipe elements and children:


<bean
         id="extracter.xml.sample.selector.XPathSelector"
         class="org.alfresco.repo.content.selector.XPathContentWorkerSelector"
         init-method="init">
      <property name="workers">
         <map>
            <entry key="/my:test">
               <null />
            </entry>
            <entry key="/Recipe">
               <ref bean="extracter.xml.sample.AlfrescoModelMetadataExtracter" />
            </entry>
         </map>
      </property>
   </bean>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍


And the mappings:

<bean id="extracter.xml.sample.AlfrescoModelMetadataExtracter"
         class="org.alfresco.repo.content.metadata.xml.XPathMetadataExtracter"
         parent="baseMetadataExtracter"
         init-method="init" >
      <property name="mappingProperties">
         <bean class="org.springframework.beans.factory.config.PropertiesFactoryBean">
            <property name="properties">
               <props>
                    <prop key="author">author</prop>
          <prop key="title">title</prop>
                <prop key="description">description</prop>
               </props>
            </property>
         </bean>-
      </property>
      <property name="xpathMappingProperties">
         <bean class="org.springframework.beans.factory.config.PropertiesFactoryBean">
            <property name="properties">
               <props>
                  <prop key="author">/Recipe/Author/text()</prop>
                  <prop key="title">/Recipe/Title/text()</prop>
                  <prop key="description">/Recipe/Instructions/text()</prop>
               </props>
            </property>
         </bean>
      </property>
   </bean>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I'm not sure what I'm missing here.  It seems pretty straight forward and I've worked off of the example that Alfresco provided, which is the exact functionality (except for the actual mappings and XPath queries), so it shouldn't be that different right?  It was kind of unclear in the wiki how to "activate" these extractors other than dropping them in /classes/alfresco/extension and removing the ".sample" from the end of the filename.  Thanks.  Any help is much appreciated.  Thanks.

Hi,

I am assuming that you took the .xml.sample file, dropped the .sample part and put it into the alfresco/extensions location.  The mechanism by which this is picked up is discussed here: http://wiki.alfresco.com/wiki/Repository_Configuration

Now, your configuration looks correct except for the mappings such as
<prop key="author">author</prop>
You'll notice that the sample uses cm:author, but you chose to use just author.  cm:author is equivalent (assuming you put in the missing namespace mapping as well) to {http://www.alfresco.org/model/content/1.0}author, while author is equivalent to {}author.  They are completely different properties.

Perform this query against your database, but you could use the Node Browser to dig down to the nodes as well:
select * from alf_node_properties where qname like '{}%';‍
and see whether there are any values there.

*To try to narrow down the problem and limit complicating factors, I've slimmed down the metadata extraction to focus on just the title field.  I figure if I can get one of them working first, the rest will fall into place.

Ok, I had followed the activation instructions like I was supposed to.  I just wanted to make sure I wasn't supposed to register the xml anywhere else (i.e. adding a line to another context xml). 

Querying for "{}%' returns nothing, but there is a '{http://www.alfresco.org/mondel/content/1.0}title'

Changing the namespaces back to the way they were in the sample file hasn't changed the output.  Title remains null.  Here's my latest configuration:



<bean id="extracter.xml.sample.AlfrescoModelMetadataExtracter"
         class="org.alfresco.repo.content.metadata.xml.XPathMetadataExtracter"
         parent="baseMetadataExtracter"
         init-method="init" >
      <property name="mappingProperties">
         <bean class="org.springframework.beans.factory.config.PropertiesFactoryBean">
            <property name="properties">
               <props>
                  <prop key="namespace.prefix.cm">http://www.alfresco.org/model/content/1.0</prop>
              <prop key="title">cm:title</prop>
               </props>
            </property>
         </bean>
      </property>
      <property name="xpathMappingProperties">
         <bean class="org.springframework.beans.factory.config.PropertiesFactoryBean">
            <property name="properties">
               <props>
                  <prop key="namespace.prefix.fm">http://www.alfresco.org/model/forum/1.0</prop>
                  <prop key="title">/Title/text()</prop>
               </props>
            </property>
         </bean>
      </property>
   </bean>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

No combination of the namespaces seems to be working.

How are you testing the extraction?
Where did you put the extension file?
Post the startup logs with the following on DEBUG: org.alfresco.repo.content.metadata

I actually put the extension in 2 places (one at a time, then together) because I was unsure about which one it should really go in:
-C:\Alfresco\tomcat\shared\classes\alfresco\extension
-C:\Alfresco\tomcat\webapps\alfresco\WEB-INF\classes\alfresco\extension

Here's the log from my most recent startup:

*There were a couple words that your forum's spam filter picked up (MP_3 and mu_sic).  I put an underscore to beat the filter.


And to test, every time I change something in the configuration, I go to my test space that contains a few existing documents, clear out any old rules, create a new Inbound metadata extraction rule, reapply the rule to the space, then Add content and upload a new xml of the same structure.

From the Wiki:
The first thing to decide is if the set of registered extractors for WCM must be the same as the that available to the Alfresco Document Management framework. In our sample, this has not been done;
To test the sample, add one of the Alfresco model files to a web project.
So, the extractor is not available outside of WCM.  To make it available outside of WCM, remove the metadataExtracterRegistry property.  The extractor will use the registry defined on the base bean, i.e. the metadataExtracterRegistry and will be available for use in the normal document management side of things.

And C:\Alfresco\tomcat\shared\classes\alfresco\extension is the correct place.

Just wanted to close this issue out.  Derek's info has come in helpful in trouble shooting, but the root problem seemed to be in the 2.1.0 beta 1 release. By updating to the 2.1.0 beta 2 release, all the problems have been solved.
