There is some buzz around our recent announcement about our partnership with Discretix to collaborate on the Interoperability of DRM. Louise Wells mentions the difficulties of standardized and interoperable DRM.

I would like to add to that though, that in my opinion two aspects are crucial if it comes to interoperability:

1. Ensure IOP among implementations of open standards like OMA DRM
2. Find ways to make different DRM schemes to work among each other - including the trust model

When it comes to the first, the OMA selected Coremedia DRM as the reference implementation some months ago. About 30 companies already rely on CoreMedia for DRM interoperability including the top handset providers, leading operators and many componment manufacturers

The second aspect is more complicated to achieve. From a technical point of view, OMA DRM allows the import and export of content to and from other DRM schemes.How to combine different trust models is much longer discussion I will not go into now... that said, several baby step activities are happening behind closed doors...

So, how many baby steps sum up to a big bang?
