Document properties (title, subject, keywords, etc)

[goeh]

Adding document properties was much harder than expected, but I finally made it. I had to move code from WordDocument to WordDocumentBuilder and add relationships for app.xml and core.xml, and some other stuff.

In the document DSL you can now add a metadata Map like this:

document(font: [family: 'Arial', size: 12.pt],
                metadata: [company: 'Groovy Documents Inc.',
                           manager: 'Craig Burke', author: 'Göran Ehrsson',
                           subject: 'Test', title: 'Test of document properties'],

Document metadata is currently stored in a Map on Document but maybe we should use a type DocumentMetadata so we get strong typing and can validate metadata. Now that I've done both Word and PDF I can see that there is only a limited set of standard properties that can be set.

class DocumentMetadata {
    String title
    String subject
    String description
    String keywords
    String author
    String manager
    String company
    String category
    String revision
    Date created
    Date modified
}
