Document properties in inkscape

We need to take care about compatibility, ie. roundtrips of the odf with other
tools like OpenOffice, Calligra, with alien formats such as from MSO and when
exporting/importing the image as SVG, for example.

As of SVG, Inkscape has some tags shown in the attachment. Those are saved in
the metadata
