Introduction

This page is the home page for the CO2*CRC online catalogue documentaion, including its setup, administration and usage.

Architecture

The CO2*CRC data catalogue uses Geonetwork opensource (geonetwork for short) as an online catalogue for its data. This web based catalogue provides an easy way for researchers to locate, query and access their data. Each entry contains some metadata including (among others) a title, abstract, georeference and a link to download the associated data. The data can be in theory stored anywhere, but it is strongly recommended to use the ARCS data fabric unless the data already exists in another available location.

Setup

Installing geonetwork

The installation procedure for geonetwork is documented on this page.

The exact details of the machine hosting geonetwork are not known yet and should be recorded here soon... (-- ThomasPoulet - 27 Jan 2011)

Administration

The policy to handle the administration of the CO2*CRC catalogue has not been decided yet and there is no primary person of contact yet. (-- ThomasPoulet - 27 Jan 2011)

Usage

Entering data in the catalogue

To enter data in the catalogue you need to:
  1. upload the data to the data repository. It is strongly recommended to use the ARCS data fabric (by following the user guide for example)
  2. Note the URL of the data. This URL is given to you when you upload data in the ARCS data fabric
  3. Create a new entry in geonetwork, including all metadata relevant to this entry, which includes the URL to download the associated data. This step can be done through various methods as explained below.

Uploading data to ARCS data fabric

Detailed instructions are available on ARCS data fabric [[http://www.arcs.org.au/index.php/component/content/article/76-data-services/319-data-fabric-user-guide][user guide][user guide]], and you can contact the (very friendly and responsive) customer service (customerservice@arcs.org.au), but in short:
  1. You need to be registered to use ARCS services.
    1. go to the ARCS web site and click on the register link in the top right corner

    2. log in using an identity provider in the list (your institution) and the corresponding username and password. If your institution is not in the list, email the customerservice@arcs.org.au
      Select_identity_provider.png
    3. you'll be given an ARCS username, chose a password. You'll then receive a confirmation email telling you that an ARCS-DF user-environment has been created for you and that you can now use the ARCS Data Fabric.
  2. Go to the ARCS data fabric web site: http://df.arcs.org.au/ARCS/home
  3. log in through your selected institution and you'll get a home page that looks like this:

  4. Navigate through the links where you want to upload your file and click on the Upload File button then. If I upload for example the file results.zip in my thomas.poulet folder I can then access it from now on through the URL http://df.arcs.org.au/ARCS/home/thomas.poulet/results.zip. In practice, the CO2*CRC catalogue administrator will have to decide on a policy regarding the architecture required on the Data Fabric. Florian Goessmann at ARCS (florian.goessmann@arcs.org.au) is the best person to talk to about this architecture decision and he is expecting to be contacted on the subject. A similar setup has been done for IMOS for example, with public and restricted directories.

Entering a single data manually in geonetwork

  • Log in to geonetwork as a user with administrator privileges
  • Click on the Administration link in the top left corner
  • Click on the New metadata link (second link from the top on that page)
  • Select a template in the list provided (if you don't know select the preferred one!) as well as the group authorised to access the new entry you're creating, and click Create
  • You must now enter all the metadata you have regarding this entry in the corresponding fields.

    There is a menu on the left hand side to access all metadata to enter, but not all fields must be filled in (a policy should be defined by the administrator). In practice the most useful pages to fill in are:
    • Identification, to fill in the title, date, abstract, point of contact and the keywords. (Note: authorised keywords might be defined by the administrator for standardisation purposes)
    • ???
    • Distribution. This page references the corresponding data associated to this entry. Click on the little "+" signs to create as many items Transfer options / Online resource as you want links to appear for this entry. For each link, copy the URL (you obtained from the ARCS data fabric for example) in the URL field.
