Table of Contents

 

1. Introduction

This document presents the configuration procedure of the VESPA service installed during the first part of the tutorial. We propose here to set up the Registry configuration (Section 2), as well as a test TAP service (Section 3). 

In all this document, you will have to replace all text between <<...>> with the value that you have selected for your installation.

In order to prepare the installation, here is a table to be filled with the parameters of you installation:

The Paris Astronomical Data Centre aims at providing VO access to its databases resources, at participating to international standards developments, at implementing VO compliant simulation codes, data visualization and analysis softwares. Paris Astronomical Data Centre offers a central support to the various projects through central storage and web servers computing facilities.

Founded in 1667, the Observatoire de Paris is the largest national research center for astronomy. About 30% of all French astronomers are working in its five laboratories and its institute. Situated on the Paris, Meudon and Nançay campuses, they are all associated with the CNRS and, in many cases, with the major scientific universities in the Paris area. The research done at the Paris observatory covers all the fields of contemporary astronomy and astrophysics.

(1) This ivo-id is that of your naming authority. If your institution is not registered you should put ivo://<<authority_name>>/org (see Tutorial Part 1).
(2) May be different from the maintainer_email. Contact Name is the Data Center contact person, whereas the Creator Name is the contact for this specific server.
(3) The logo must have the following maximum dimensions: width = 120px and height = 60px.  
(4) This date must be formatted in ISO-8901, see the example caution on format. 

2. DaCHS Registry Configuration

The Registry is the Information System of the Virtual Observatory (the yellow pages where all the services are registered). We describe a way to register your "authority ID" (description of the authority managing your resources) and the services provided by DaCHS. This operation shall be done only once. New services will be registered automatically.

First you need to create an identifier for your naming authority ID (ivo://authority_name)

Then open the configuration file:

...and edit it with the following lines (see Tutorial Part 1 for some keywords):

 

Then you have to update the userconfig.rd file in the same directory. This file does not exist yet on a fresh installation, so you have to create it. You first need to switch to the root user, and then create the file: 

Then open the registry-interfacerecords section of the userconfig.rd file for editing

And in the file, remove the {UNCONFIGURED} text, so that the content is:

In case your organisation is already registered, you need to remove the <resRec id="manager"> ... </resRec> element.

Once this is done, we can publish your registry interface, by issuing the following command:

Read http://docs.g-vo.org/DaCHS/opguide.html#defining-basic-metadata for more details

3. Registering the DaCHS server in Registry of Registry

Go there: http://rofr.ivoa.net/regvalidate/

Enter the URL: http://<<dachs-server-address>>/oai.xml

First step on registry validation result on failed tests have to be None Found

Then a "Step 2: Register your Registry" will be proposed on the web interface with a button Register

Once you registry is inside the list of publishing registries, you have to wait at least one day for the information to be harvested and to see your service available in clients like Topcat

 

4. Unregistered a service

In case you build a test service and you register it by mistake, we describe how to set this service as inactive so it will not be visible on the registry any more.

In the q.rd file defining your service you have

<data id="collection" auto="false">
      <make table="epn_core"/>
      <publish/>
</data>

remove the line          <publish/>

make under dachsroot the command   gavo pub q.rd

to be sure that the declaration have been removed go to

http://<<dachs-server-address>>/oai.xml/verb=ListIdentifiers&metadataPrefix=ivo_vor

your collection will appear in strike characters

 

 

Assessing your dataset

Depending on your dataset (just a series of files, number for data processing levels, presence of metadata, format of data, existing relational database...) various processing may be required. In order to prepare the sharing with EPN-TAP, here is a check list of what you need:

  • Public access to the data files you want to share: either on your server, or on a remote server with a publicly accessible URL (e.g., at NASA/PDS or ESA/PSA).
  • Metadata (relevant for EPNcore) for each file
  • Preview image for each file

Select a suitable data format if the current format is recommended by VESPA.
