This is a split refactored from an older post containing too many questions about licenses in SVG Tiny 1.2 using RDFa as suggested by Patrick Hoefler. See also question Interest of double lincenses CC-BY-SA + ODbL for SVG maps.
Introduction
LittleMap.org aims to allow anyone editing maps for blind people. I think the best way to share maps is as SVG files.
RDFa, DC and CC tags
I also think the best way to embed licenses (and geographical coordinates) within SVG file is to use RDFa (see my previous question).
Question
Is my below <metadata>
correct in order to embed both CC-BY-SA-4.0 and ODbL v1.0 within SVG file? Is there a "more" correct/standard way? Please suggest improvements.
