Example: original URI vs. trusty URI Based on the paper: Kuhn, T. , Dumontier, M. : Trusty URIs: Verifiable, immutable, and permanent digital artifacts for linked data . Proceedings of the European Semantic Web Conference (ESWC) pp. 395–410 (2014). A trusty URI is a URI that contains a cryptographic hash value of the content it identifies. The authors introduced this technique of using trusty URIs to make digital artifacts, specially those related to scholarly publications, immutable, verifiable, and permanent. With the assumption that a trusty URI, once created, is linked from other resources or stored by a third party, it becomes possible to detect if the content that the trusty URI identifies has been tampered with or manipulated on the way (e.g., trusty URIs to prevent man-in-the-middle attacks ). In addition, trusty URIs can verify the content even if it is no longer found at the original URI but still can be retrieved from other locations, such as Google's cache, ...

I've told all the members of my research group they should watch this, so I thought I might as well make the same recommendation to the rest of the world... Herbert Van de Sompel presented "Towards a Machine-Actionable Scholarly Communication System" at LIBER 2011 in Barcelona, Spain on June 30, 2011. You really have to simultaneously watch the video and review the slides to get the full impact of the presentation. The first part is a succinct review of various projects, but starting at slide 16 ("nanopublications") things really get interesting. Well worth the 40 minute investment.
