@sanjaybandhniya  Replied here alread: https://hub.alfresco.com/t5/alfresco-content-services-forum/how-to-preserve-original-document-create...

Sharing the response on this thread of clarity.

Find the demo project here:

https://github.com/abhinavmishra14/alfresco-metadataextraction-demo

I had an observation between community and enterprise versions. Examples i gave above works perfectly fine with enterprise versions of 5.2.x (i used 5.2.6) and 6.1.x(used 6.1), but properties files are not getting picked correctly (its some sort of intermittent behavior) on community editions. 

Only change i did is highlighted below for community edition and it picks up always corretly.

<property name="mappingProperties">
    <bean class="org.springframework.beans.factory.config.PropertiesFactoryBean">
	<property name="location">
	   <value>classpath:alfresco/module/${project.artifactId}/metadataextraction/TikaAutoMetadataExtracter.properties</value>
	</property>
    </bean>
</property>

On enterprise version both works fine, above path and below given path as well:

<value>classpath:alfresco/metadata/TikaAutoMetadataExtracter.properties</value>

This one also works on both versions:

<value>classpath:alfresco/extension/metadata/TikaAutoMetadataExtracter.properties</value>

https://github.com/abhinavmishra14/alfresco-metadataextraction-demo/blob/master/metadata-extractor-d...

I am not sure what difference the two type of versions (community and enterprise) has in terms of extension points, tried looking at source code but no clues. But good news is that the other path i shared above (available in demo project) works fine for both community and enterprise versions.

Hope this helps.

I tested on jpeg and png images i have and works fine for them. If tika is able to extract "created" metadata it would apply that. For the images where you are not seeing the created/modified metadata, try checking what you get in the log for 

Found: {....}

Mapped and Accepted: {....}

Like this one:

Ideally it should also work for images/files uploaded via FTP as well because extraction is happening after nodes are already created in repo. I haven't checked for FTP though.

By looking at the log you shared, i can see it is extracting created and modified metadata and it is mapped-accepted and changed as well (highlighted in red).  Did you verified the image in node browser to see whether these "changed" properties are applied ? Based on log it should be available. I am not sure why you can't see these changes.

I am not sure why metadata extraction is not triggering when you upload via FTP, I have not checked it. Try debugging
