This working group (members) concerns a broadly defined and broadly applicable set of technologies (the "stack of technology") that can be used to promote the ability of project-level scientists to build web-based data and processing services that are readily found and used by others. Part of this effort is to promote interoperability between individual services in order to help scientists pursue more integrated science.

As the group progresses, every-other-week conference calls will be held to hear about topics of interest to the group and to work on documentation for the technology road map.

Technologies being discussed by the group are being documented on this page. The current stack of technologies the group is working to understand are included in the table below.

Ideas the group may be interested in addressing were outlined by following three "Open Space" groups at the 2010 August CDI workshop: 

  1.  "Unified Access Framework for Gridded and Vector Data", was primarily concerned with bringing existing digital data into the open via open standards.
  2.  "Discoverability and Interoperability of Web-based Data and Processing Services", was concerned with process level interaction and operationalising metadata and data interchange between projects using a particular stack of open standard protocols.
  3. "Web Application Integration Framework", proposed a project to port existing National Map configurations to other clients (like arcmap). This project currently is focused on visualization, but there is interest in building in WCS, WFS, and potentially other data transfer formats.

In August 2011, the CDI reconvened as a whole and the TSWG gave an overview of progress and a plan for the future. Go here for a summary of the meeting and to see recordings of the many presentations.
