Data Discovery Tool (version 1.5) [VAO]

Data Discovery Tool (version 1.5)

From the post:

The VAO has released a new version of the Data Discovery Tool (v1.5) on June 21, 201[3]. With this tool you can find datasets from thousands of astronomical collections known to the VO and over wide areas of the sky. This includes thousands of astronomical collections – photometric catalogs and images – and archives around the world.

New features of the Data Discovery Tool include:

  • The AstroView all-sky display no longer requires Flash or any other browser plug-in.
  • All source metadata is preserved when data, such as catalogs or image lists, are exported from the DDT to a VOTable.
  • Scatter plots are available for any result tables that have at least two numeric columns.
  • More accurate footprint displays for cases where the image data resource provides more than the minimum set of image metadata.

I corrected the release date in the text. It originally read “2012,” which is incorrect.

Astronomy is an interesting area of “big data” and where there are some common semantics (celestial coordinates) but semantic diversity (publications) is also present.

It also has a long traditional of freely sharing data and making it possible to process very large data sets without transfer of the data.

Not a bad model.
