AstroTaverna Plugin Beta Release

[Jose Enrique Ruiz]

Dear App enthusiasts and Interop followers,

We are pleased to announce the release of AstroTaverna, a plugin for the
Taverna 2.4 workflow engine that makes VO web-services first-class building
blocks for Taverna workflows. It also provides astronomical data
manipulation and transformation tools based on the STIL toolset, as well as
SAMP connectivity.
Now, with AstroTaverna plugin you can:

   - Search in the VO Registry for ConeSearch (tabular), SIA (images), and
   SSA (spectra) data services
   - Add found VO services to the workflow with one click, with optional
   parameter freeze
   - Render VOTables as tabular data in the Results perspective, together
   with their field's metadata
   - Resolve astronomical object names into equatorial (Right Ascension,
   Declination) coordinates using the Sesame service.
   - Convert coordinates between equatorial, ecliptic, galactic, and other
   systems
   - Manipulate VOTables:


   - Join columns between tables with common keys
      - Concatenate two tables or more with the same columns
      - Select columns from a table
      - Select rows from a table from a conditional expression on field
      values
      - Addition of new columns based on calculations
      - Addition of extra coordinate columns, computed from existing
      coordinates
      - Convert between different input and output table formats (supported
      by STILTS): VOTable, FITS, CSV (comma-separated values), TST
(tab-separated
      text), ASCII, HTML...
   - Send VOTable results to SAMP-enabled VO software
