What you are basically asking is ability to map the different mime types to content types. I don't believe we have this capability at this point.

You can achieve this effect through space rules, however. There are conditions that allow you to pick out specific mime types, and an action that allows you to "downcast" a type - called "specialise the type of an item". Then any time a pdf comes into a space, it will downcast it into the type you want with the extra properties.

Yet another way to do this would be to create a content policy that monitors when you are adding a content of a certain mime type, and adds an aspect with the extra properties you'd like to add.

Thank you for your information.

Could you suggest me a tuttorial, an example, or something like this of how the above could be done?

Play around with space rules. When you create a space and go to properties of it, there is a section that allows you to create rules.

Check out the Tutorial included with all the installations - it's at Company Home \ Data Dictionary \ Guest Home. page 17.

I did some aproach that is being polished…

Alfresco have the posiblity to execute JScript on some events, like 'onContentUpdate' or 'onCreateNode'

you can check the document properties (ie: file extension) in the JScript and specialize the document if you like…

i don't have the reference that I used right now… but you can search for 'policyRegistration' that is the class that let you intercept those events…
