Why does Marlin approach rights expression the way it does, rather than by using a declarative language Rights Expression Language (REL) like ODRL or XRML?
The byte code engine at the heart of Marlin makes it easily extensible. Marlin can respond to new architectures, business models, and distribution models by organically building new profiles. The byte code itself is compact and easily extensible, thereby future-proofing the specification. The byte code is also easier for small devices to process than an XML REL expression.
