Getting site information from VORS

VORS (Virtual Organization Resource Selector) provides information about grid sites similar to GridCat. You can find VORS information here.
As per information received at a GOC meeting on 8/14/06, VORS information is the to be be the preferred OSG information service. VORS provides information through the HTTP protocol. This can be in plane text format or HTML, both are viewable from a web browser. For the html version use the link:

Virtual Organization Selection
The plain text version may be more important because it can be easily parsed by other programs. This allows for the writing of information service modules for SUMS in a simple way.

Step 1:

Go to the link below in a web browser:

VORS text interface

Note that to get the text version index.cgi is replaced with tindex.cgi. This will bring up a page that looks like this:

This page holds little information about the site its self however it links the site with the resource number of the site. The resource number is the first number that starts each line. It this example site STAR-BNL is resource 217.

Step 2:

To find out more useful information about the site this has to be applied to the link below (note I have already filled in 217 for STAR-BNL):

STAR-BNL VORS Information

The plane text information that comes back will look like this:

From the unix command line the command wget can be used to collect this information. From inside a java application the Socket class can be used to pull this information back as a String, and then parse as needed.
