   * **Changing Your Archive From a Black Hole to a Gold Mine** -- //Jay Lofstead (Sandia National Laboratories)//​ \\ Archives have been a crucial part of long term data storage ensuring that future users can refer back to previous work to check new results integrity or to deal with compliance and legal requirements. However, making these archives more useful than write-once, read-never systems has been challenging. Tape speeds, when compared to other storage media, have high latency making any interactive exploration painful. POSIX style attributes and extended attributes can only offer so much additional information. We are exploring offering another layer on top of the archive that can make archive item selection more efficient and effective turning your data black hole into a gold mine.   * **Changing Your Archive From a Black Hole to a Gold Mine** -- //Jay Lofstead (Sandia National Laboratories)//​ \\ Archives have been a crucial part of long term data storage ensuring that future users can refer back to previous work to check new results integrity or to deal with compliance and legal requirements.

   * **NGI initiative: toward a bridge in the semantic gap** -- //​Jean-Thomas Acquaviva (DDN)// \\ Most of the recent innovations in the storage area have been driven by the cloud emergence. This had led to a race toward genericity and ultimately to the now ubiquitous object interface. While this has been highly beneficial for the community the absence of semantic is a drawback for the HPC ecosystem. The NGI initiative is an effort coming from the weather forecast community aiming at bringing *more* semantic in the data format. We advocate to bring application closer to data and pave the way for on situ computing data format should be richer and more specific.   * **NGI initiative: toward a bridge in the semantic gap** -- //​Jean-Thomas Acquaviva (DDN)// \\ Most of the recent innovations in the storage area have been driven by the cloud emergence.
