Thinking about this... I haven't had time to look at the latest version of the 'benefits' but presumably this is complimentary to the 'costs'? I think that the benefits of expressing 'traditional' library data as LD is more than just discovery (and indeed, many 'discovery' benefits might be realised without doing full LD representations) - so aspects of data re-use, machine processable data etc. is part of this. It might be worth exploring this question of native vs converted LD further. I'm thinking there are probably different sets of costs. Doing basic LD representations from MARC should be straightforward once a few have trail-blazed and shared conversion routines etc.? However, cost of matching entities etc is high. Some of these costs go away when you create library data natively as LD - but the associated costs of doing this feel v high (redeveloping systems to cope etc.!)
