     <p>
       DAWN, Data Analysis Workbench, (<a target="_blank"
         href="http://www.dawnsci.org/">www.dawnsci.org</a>) is a
       RCP-based application used in Synchrotrons, Neutron Sources and
       Universities for visualizing and slicing data and running analysis
       software. DAWN is primarily developed at the Diamond Light Source
       (<a target="_blank" href="http://www.diamond.ac.uk/Home.html">www.diamond.ac.uk</a>)
       however developers and collaborators from around the world are
       active with the codebase which is open source and available on
       github. Most of the users of DAWN either download the binary or
       have a version installed at their institution.
     </p>

     <p>DAWN's visual tools are contributed from extension points and
       there are a large number of different options available to users
       when visualizing data. From slicing of multidimensional data to
       integration, selection regions to 1D mathematics or custom
       specific scientific tools; DAWN is a powerful tool.</p>

     <p>
       Software to analyse data is available in three forms within DAWN.
       Java-based algorithms configured by a user interface inside DAWN,
       third party codes run on a compute cluster of various kinds and
       finally python scripts developed directly inside DAWN, using Pydev
       (<a target="_blank" href="http://www.pydev.org/">www.pydev.org</a>).
       DAWN provides a rich CPython API for use inside the product, so
       for instance plotting and file readers are accessible for
       scripting.
     </p>

     <p>
       The team tries to make DAWN as generic and reusable as possible.
       DAWN is repackaged and released in three other products with
       others evaluating. There are some videos of DAWN at different
       points of development at <a target="_blank"
         href="http://www.opengda.org/dawnsci/videos/">www.opengda.org/dawnsci/videos</a>.
     </p>

     <h2>DAWNSci and the Eclipse Science Working Group</h2>
     <p>
       Diamond Light Source have been involved with forming the Eclipse
       Science Working Group and are committed to working with the
       community to make tools modular and reusable between disciplines.
       It would be great if serendipitous discoveries could be made by
       applying tools developed for one discipline in another and of
       course the reduction of effort where existing tools can be reused
       rather than redeveloped. Working with the Eclipse Foundation and
       members of the group, we hope to make available the ‘DAWNSci’ (<a
         href="http://projects.eclipse.org/proposals/dawnsci">projects.eclipse.org/proposals/dawnsci</a>)
       eclipse project first quarter of 2015 on github. We have
       abstracted much of the DAWN API into interfaces/services for
       plotting, data, file reading and conversion, slicing and much
       more. This API we will commit to supporting an implementation,
       long term and encourage alternative implementations, which will
       make tools and algorithms reusable.
     </p>

     <h2>DAWN Under Development</h2>
     <p>
       DAWN is released at every shutdown of the Diamond Synchrotron,
       about 4 or 5 times per year. The next release, DAWN 1.8, will be
       in March 2015. In this version we will provide the ‘Processing’
       perspective to make a model based execution engine where users can
       visually build components to complete custom analysis. We would
       like to use EMF in future for the user interface and the execution
       engine is based on Ptolemy 2 (<a
         href="http://ptolemy.eecs.berkeley.edu/">ptolemy.eecs.berkeley.edu</a>)
       developed with help from Isencia Belgium (<a
         href="http://www.isencia.be/">www.isencia.be</a>). In 1.8, DAWN
       will be extended to allow all of the user interface to be scripted
       by CPython. Users will be able to record macros to see the
       commands which the user interface is generating. Normally the
       interface will be driving an OSGi service so all the OSGi services
       will be available to the cpython layer running in Pydev. It is
       also hoped that, using reflection, we will be able to autocomplete
       the cpython calling Java objects. Several new scientific tools
       will be added in 1.8 for specific tasks for example spectroscopy,
       ptychography, image alignment and circular dichroism.
