I wasn't aware of the document yet, so thanks for pointing it out. Do you think there is a good chance that the DWBP initiative will come up with a vocabulary that includes things like Coordinate Reference System and spatial resolution? Those are concepts that may be too specific to make it to general vocabularies. I guess it comes down to scope. Are properties like Coordinate Reference System and spatial resolution more in scope of LOCN or DWBP? LOCN is about individual things (places) rather than datasets (collections of places), but I think that properties like Coordinate Reference System and spatial resolution could be applied on both levels. Perhaps it is a good idea to start making some solid proposals for extensions of LOCN? It could be that just trying to define the necessary properties will help in determining which vocabulary they could best be part of. I could give it a try, after I get back from my four week vacation. If I have done things right this list won't receive automatic out-of-office messages when I am away, so this way you will know that I am not being rude when I don't respond to e-mail for a while.
