<p style="margin:0in"><span style="font-size:10.5pt;font-family:"Arial",sans-serif;color:black">A Science Platform is an environment providing advanced functionality to analyze and process large and complex data-sets close to the data. In recent years the Grid
and Web Services working group has been focusing on Science Platforms as a complementary approach to downloads that are traditionally still part of our standardization efforts. As data sets are getting ever larger and more complex, for many use cases it becomes
imperative to bring analysis to the data.</span><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p style="margin:0in"><span style="font-size:10.5pt;font-family:"Arial",sans-serif;color:black">In particular this is true for the results of large scale computer simulations. Standardization has proven complex for theory data and by their nature simulations
results often require statistical analysis of large data sets. Over the years simulation groups have disseminated their data using a variety of approaches, but setting up a full-fledged science platform poses substantial technological challenges in terms of
discovery, access, processing and </span><span style="font-size:10.5pt;font-family:"Arial",sans-serif">possible<span style="color:black"> standards.</span></span><o:p></o:p></p>

<p style="margin:0in"><span style="font-size:10.5pt;font-family:"Arial",sans-serif;color:black">In this workshop we want to bring together scientists, experts in computational Cosmology, VO experts and SP developers to discuss current implementations and ideas
for their future development. In particular we want to identify areas where a common, standardized approach might benefit the community, which the IVOA could take up in its efforts. This may include metadata standards for discovery, or standards for file formats,
compute environments, or data access libraries.</span><o:p></o:p></p>
