Geoscience Australia's metadata catalogue

Submitted by admin on Mon, 04/30/2018 - 22:41

Geoscience Australia (GA) is a government organisation in charge of geophysical and spatial data. It maintains a large catalogue of public, scientific, datasets online at [http://ecat.ga.gov.au/geonetwork/](http://ecat.ga.gov.au/geonetwork/). The catalogue is implemented using the [GeoNetwork](https://geonetwork-opensource.org/) tool which is an online, document database system. Records are all stored according to the [ISO's 19115-1:2014 metadata standard](https://www.iso.org/standard/53798.html). In addition to utilising that standard, GA has extended it with it's [own profile](http://pid.geoscience.gov.au/def/schema/ga/ISO19115-1-2014) which, among other things, implements code list extensions. The code list relevant to this implementation is the *DS_AssociationTypeCode* codelist which defines how a catalogued resource is related to another catalogued resource or an esternal resource indicated by a hyperlink. The GA extensions include types taken directly from PROV, such as *wasDerivedFrom*, *hadDerivation*, *wasGeneratedBy*, *generated*, *wasInformedBy* and *informed*. This allows resources associated with other resources with the type indicated by these codes to be interpreted as PROV, for example:

Dataset 82033 was derived from Dataset 70908.

In the catalogue's ISO19115-1:2014, Geoscience Australia profile, XML record for Dataset 82033, using the code list extension for *wasDerivedFrom*, this is:

Using the persistent URIs for the datasets 82033 &amp; 70908 which are <http://pid.geoscience.gov.au/dataset/ga/82033> &amp; <http://pid.geoscience.gov.au/dataset/ga/70908> respectively, this can be interpreted as the [RDF](https://en.wikipedia.org/wiki/Resource_Description_Framework) triple, using the [PROV ontology](https://www.w3.org/TR/prov-o/) as:

<code><pre>&lt;http://pid.geoscience.gov.au/dataset/ga/82033&gt; prov:wasDerivedFrom &lt;http://pid.geoscience.gov.au/dataset/ga/70908&gt; .</pre></code>
