Hi Nick,
Some questions arise for
me:
1)
Where did you get this information from?
2)
The information you presented seems not to be the GRIA services but
kind of “instances” created with the services. Do not mix up a Data
Service and a Data Stager or a Job Service and a Job. What we would like to
have from the info system are the services and not the Data Stagers for
instance. A Data Stager itself corresponds to a Grid Connection in the
g-Eclipse sense and can be created from a Data Service using the mount action. Maybe
I am wrong here but for me it seems that we are talking about different things
here.
Maybe IT Innovation can clarify
…
Cheers, Mathias

Information Gathered
Hello everyone. I have been looking in how to get
information about the GRIA services and data and I have managed to get the
following:
I got all the services that are provided by our example GRIA server in
iwr-geclipse.fzk.de. I can get the information in the following xml format:
<?xml version="1.0"
encoding="UTF-8"?>
<application xmlns="">
<name>http://it-innovation.soton.ac.uk/grid/imagemagick/swirl</name>
<version>1.0.0</version>
<description>Application to swirl an
image</description>
<application-inputType>
<name>source-image</name>
<type>jpg</type>
<description>image file of any
type</description>
</application-inputType>
<application-outputType>
<name>swirled-image</name>
<type>jpg</type>
<description>swirled image of the
same type as input type</description>
</application-outputType>
</application>
As you can see I also get the inputs and the outputs of the job.
I also managed to get the data staggers that I had created with the GRIA client
in xml format like:
<ns4:title xmlns:ns4="http://purl.org/dc/elements/1.1/">MyData</ns4:title>
<ns5:serviceresourcetype xmlns:ns5="http://it-innovation.soton.ac.uk/2005/grid">http://www.it-innovation.soton.ac.uk/grid/resource/data</ns5:serviceresourcetype>
<ns6:status xmlns:ns6="http://it-innovation.soton.ac.uk/2005/grid">full</ns6:status>
As you can see I get the title of the data stagger and whether it is full or
empty. I think this information is enough for the infosystem to provide. If you
agree with me in this, then this means that we will not need the registry
service that Ariel tries so hard to install :)
