Get Node content modification time

eureka — Thu, 18 Apr 2013 09:46:53 GMT

Is it possible to get the modification date of one node's content? I know there is the auditable aspect's proerty cm:modified, but it gets updated even if you edit any of the node's properties. Do I have to add a custom property to be updated onContentUpdate? Do I have to modify the auditable behavi

I think what you are looking for is the date on which the document itself is updated not its metadata is it the case?
Please confirm

There are no separate properties for the modification time of properties of type content.

Further thoughts:
a) It would be fairly easy to add a new custom property driven by a policy when content is updated.

Hi,

I think that Alfresco stores the content in the content store depending on the date it was modified.

So you only have to parse the contentUrl metadata property on the node. You can check if this is true on a node browser.

While that may work for some cases the layout of the content store is not intended to be queried like that. Yes the repository is by default laid out in that way in order to assist with incremental back up, however be aware that you can add content on any path so its not guaranteed to work.

Hi all,

thanks for all your replies.

Yes, I was thinking to the date when the content of the node is actually updated. I think I can add a property to my base class and bind a behaviour to the onContentUpdatePolicy that update this property.
My concern is how to handle all the nodes already there in the repository.
Is it somehow possible to default the property value of my newly added modifcation time property to the value of last cm:modified?

@jspuchau
I need a property to exec lucene queries agaainst. I don't think i can retrieve that information, am I wrong?

Regards

Yes you can do it easily.
You can simply create a script which will copy default modified date value to your new property for all the existing contents.
And you can attache that script with rule and apply that rule to folder under which all your contents are lying.

@mitpatoliya: it doesn't work because you can apply a space rule to content that
1) are created or inserted in the folder
2) are udated
3) are moved ore delted

Content already there doesn't get picked by any of these condition
