how to generate contents/files automatically ?

[zeldoune]

I start with Alfresco and I'm asking if it exists a way to automatically generate documents (files) from the metadata of a set of contents of the same type or from the contents themselves. (By automatically I mean using a business rule or a workflow.) For example, is it possible to automatically create a text file containing the authors' list of a the contents in a given folder? Or the titles' list of the contents from a given author ?
Thanks

Yes of course.

Just use the Java or Script API.

Thanks for your answer.
Could you be a little bit more specific please. I'm  starting and I don't see all the possibilities yet. I try to rephrase my ask in order to be clearer.  The intention is to create a content only from his metadata. What is the best way to generate a file (for example a pdf) from meta-data ? Is it a good way to generate a content like this with Alfresco "create content wizard" ? Would it be  more satisfying to use a kind of form ? After fill in informations in the form would it be easier to generate a pdf or text file ? (and to add it in a specific space).
Thanks
