Changing Alfresco repo content to read only

[maverick]

Hi,
Is there a way to change content properties  written by Alfresco to a storage?
For e.g. how to proceed if contents attributes needs to be changed to read only once the content has been stored by Alfresco to a specific repository?

Any points, how to start will be really helpful.
Thanks,

Content is read only in alfresco.   Although it can be deleted.    You can prevent deletion in alfresco if you want.

Or you can make the entire repo read only by setting the read only property.

Thanks mRogers,
When we make the repo or content read only, Does it modifies the file attributes or just prevents Alfresco from deleting it. For e.g. if Alfresco sets a file/repo as read only and later I try to access the repo directly as a network share (lets say as CIFS or NFS mount), will I see the content properties as read-only?

Is there a way to do more than making the files Read only. I basically want to write to WORM filesystem. Changing the content to read only sets a default retention. To set a customized retention, there is requirement to modify files access times.
I had the impression that there are some mechanism to write some Connectors which can communicate with Alfresco. As soon as Alfresco is done writing, connectors can modify the access time of the contents for a specified retention period (how long data needs to be read only).

Is it possible to write such connector or setting the content/files to read-only is the only option currently?

Basically, I want to be able to write content into repo, but once they are written they should be preserved for a specified time (before becoming deletable again)
Any thoughts.

Thanks,
