Hi Erik,

Last Friday, during the meeting of the DWBP working group, we discussed
some of your comments about linking data resources. However, we still don't
have a "concrete" proposal of how to show this as part of the BP. Could you
please give some examples of how to link data resources identified by URIs
using hypermedia ?

Thank you!
