Re: [dddwg] All set for 2015 DDDWG Workshop

Yes, it is the intention to provide the recordings after theevent, in a style similar to that used in the Warwick meeting.It may take a week or two to get them in place.

(1) Since there is>> no obvious single institution which will archive all crystallographic>> raw data, the initial strategy should be the encouragement of>> voluntary deposition in locations most convenient for authors>> (e.g. synchrotron and other instrument facilities,>> university and institutional repositories, domain repositories such as>> the Australian Synchrotron.Store). (2) Search and discovery functions>> across diverse locations would depend on common metadata identifying>> and describing data sets. The obvious candidate for an identifier is>> the Digital Object Identifier (DOI), because of the existing machinery>> to register and share DOI information. (3) Because molecular/atomic>> structural studies increasingly rely on a range of technologies and>> techniques, it would be desirable to harmonise metadata descriptions>> across as many such technologies as possible. Studying the>> `arrangement of atoms' in its most general sense - as well as>> diffraction, spectroscopy and microscopy - has long been recognized>> as fitting within the remit of the IUCr.>>>> While `metadata' enters the discussion in the context of building>> distributed systems for search/discover, identification and retrieval>> of data sets, it rapidly becomes apparent that there is much more to>> metadata than that. `Metadata' is variously defined, but the general>> sense is that it is the information that is needed to make sense of>> data, to allow its reuse, validation and critical analysis. Yet such>> `information' is itself data - data that collectively open doors to>> further avenues of study, and even new scientific insight. Standard>> uncertainties on atomic positions modify the weights that should be>> given to structural models collected in databases, and so subtly>> affect our understanding of chemical bonding or biological function>> (e.g. in knowledge-based research using the Cambridge>> Structural Database or Protein Data Bank). The raw intensities>> ignored in models based solely on Bragg peaks (i.e. diffuse>> scattering) can now be reanalysed to provide insights into correlated>> disorder. Comparison of structural models derived from X-ray>> crystallography or from NMR can deepen understanding of protein>> structure and dynamics.
