Metadata Extracter

stebans — Mon, 04 Jun 2007 14:09:10 GMT

Hi all, I'm currently writing a MetadataExtracter from Word Documents. I want to extract other properties than the default ones (author, title, description) from the properties (like keywords) and from the parsing of the document. I wrote a Java class which extends the org.alfresco.repo.content.met

Hi,

first of all, I hadn't seen there was another post about the same subject and with almost the same title (http://forums.alfresco.com/viewtopic.php?t=5687), but anyway I found the information which is in this thread on myself.

Anyway, I still cannot make the Extracter extract the metadata! Here's what I did, and, hopefully someone will be able to help me finish all this up…

1. "my custom model" xml file


<model name="my:model" xmlns="http://www.alfresco.org/model/dictionary/1.0">
   <imports>
      <import uri="http://www.alfresco.org/model/dictionary/1.0" prefix="d" />
      <import uri="http://www.alfresco.org/model/content/1.0" prefix="cm" />
   </imports>

   <namespaces>
      <namespace uri="http://***/model/dictionary/1.0" prefix="my" />
   </namespaces>

   <types>
      <type name="my:model">
         <title>My Model for Documents Metadata</title>
         <parent>cm:content</parent>
         <properties>   
            <property name="my:keywords">
               <title>Keywords for my document</title>
               <description>Keywords for my document</description>
               <type>d:text</type>
               <mandatory>true</mandatory>
            </property>
         </properties>
      </type>
   </types>
</model>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

2. web client configuration


   <config evaluator="string-compare" condition="Content Wizards">
      <content-types>
         <type name="my:model"/>
      </content-types>
   </config>
   <config evaluator="node-type" condition="my:model">
      <property-sheet>
         <show-property name="my:keywords" />
      </property-sheet>
   </config>
‍‍‍‍‍‍‍‍‍‍‍‍

3. Java class which I'm really not sure about.


package my.pckg;

import java.io.IOException;
import java.io.InputStream;
import java.io.Serializable;
import java.util.Map;

import org.alfresco.model.ContentModel;
import org.alfresco.repo.content.metadata.OfficeMetadataExtracter;

import org.apache.poi.poifs.eventfilesystem.POIFSReader;
import org.apache.poi.poifs.eventfilesystem.POIFSReaderEvent;
import org.apache.poi.poifs.eventfilesystem.POIFSReaderListener;


public class MyOfficeMetadataExtracter extends OfficeMetadataExtracter {

   static final QName PROP_KEYWORDS = QName.createQName("http://***/model/dictionary/1.0", "keywords");
   
   public MyOfficeMetadataExtracter() {
      new OfficeMetadataExtracter();
   }

   public void extractInternal(ContentReader reader,
         final Map<QName, Serializable> destination) throws Throwable {
         
      POIFSReaderListener readerListener = new POIFSReaderListener() {

         public void processPOIFSReaderEvent(final POIFSReaderEvent event) {
            try {
               PropertySet ps = PropertySetFactory.create(event.getStream());
               if (ps instanceof SummaryInformation){
                  SummaryInformation si = (SummaryInformation) ps;
                  
                  //trimPut(ContentModel.PROP_AUTHOR, si.getAuthor(), destination);
                  trimPut(PROP_KEYWORDS, si.getKeywords(), destination);                                       
                  
               }

            } catch (Exception ex) {
               throw new ContentIOException("Property set stream: "
                     + event.getPath() + event.getName(), ex);
            }
         }
      };
      
      InputStream is = null;
      try {
         is = reader.getContentInputStream();
         POIFSReader poiFSReader = new POIFSReader();
         poiFSReader.registerListener(readerListener, SummaryInformation.DEFAULT_STREAM_NAME);
         poiFSReader.read(is);
      } catch (Exception e) {
         //…
      } finally {
         if (is != null){
            try {
               is.close();
            } catch (IOException e) {
               //…
            }
         }
      
      }
   }
}

4. Bean registration in "content-services-context-xml"


   <bean class="my.pckg.MyOfficeMetadataExtracter" parent="org.alfresco.repo.content.metadata.OfficeMetadataExtracter" />
‍‍‍

I don't know if the class is supposed to work at all. Is QName PROP_KEYWORDS = QName.create(namespace, property_name) the right way to go? I'm lost!

Even if it worked out, I don't understand the way to make the mapping between Word documents of my custom content type and the extracter. Where should I configure the mapping?

Hope I'm not too far from the solution and my question is clear enough for a tip…

Thanks

Hi,

I've been spending a lot of time for extracting and viewing custom metadata from Word documents. But I'm not there yet 😞 …

I replaced OfficeMetadataExtracter with my own class and it worked out. I was able to modify metadata such as author using a QName

static final QName MYPROP_AUTHOR = QName.createQName("http://www.alfresco.org/model/content/1.0", "author");
[…]
trimPut(MYPROP_AUTHOR, "whatever author", destination);
‍‍‍‍

which is correctly reflected on the web view.
But I couldn't make it with properties from my model (be it "content type" or "custom aspect"), although I think I use the exact same way:


static final QName MYPROP = QName.createQName("http://my.own/model/content/1.0", "myprop");
[…]
trimPut(MYPROP, "some text", destination);
‍‍‍‍‍

How to be certain of the QName of my property?

Have some developers been successful with a similar case (no doubt about it!)??

Hi all,

thanks to amarendrakt, I have the solution to this blatant issue: I hadn't added the rule "Extract Metadata" ops:. I can't even believe I have forgotten about the rule. Please, write it in red somewhere, in case somebody forgets to add the rule as I did. Maybe I forgot because the "default" metadata (TITLE, AUTHOR,…) are extracted in all cases.

Again, thank you to amarendrakt and the community.

Interesting thread this one. I have a certain few questions abouut this applied to my specific situation.
I'm working with applying an aspect to the documents which define custom properties and I'd like to be able to extract them both in a Java program and in the Web interface. At this point the web interface will be prioritized. I'll go about posting my model with aspect and the config files I used with their changes.

This is probably where I'm supposed to make it happen. Although I'm unsure how the link between the actual word document and the fields I specified in the aspect exists. I haven't exactly found a great source of info on that problem as well, but that might just be me.

I have the same needs as you. I'll take a look at your examples, but where did you add the rule?

I am trying to get this working as well.

I feel that I am fairly close but have found an open jire issue that might indicate that this is not something you can do without Java coding.
Can anyone confirm this?

This is my log, the strange thing is that even though I can see the metadata extraction in the log and I know there is the korresponding property in the document it does not pick it up

Hi

I have been at it since last post still with no luck. I guess next stepp is setting up a full development environment and debugging it to find out what is wrong.

Anyway this is the JIRA issue I was refering to in the previous post (https://issues.alfresco.com/jira/browse/ALFCOM-1757), does anyone know if this has been fixed somewhere?

Here is a little more information about our setup/configuration
This is our setup

Alfresco Version: Labs - v3.0.0 (b 1164)
Installed on tomcat running on mysql (Redhat Enterprise)
