GSQ Dataset Profile

This is a model of a general dataset.

Fig. 1: The general model of a dataset (after DCAT (rev)).

It is a profile of the DCAT (rev) Dataset Catalogue Vocabulary model of dataset's metadata. It is used for describing the Geological Survey of Queensland (GSQ)'s datasets which are listed in a dataset catalogue.

In addition to profiling DCAT (rev), this profile, through published alignments of DCAT (rev) is mapped to ISO 19115-1:2014 Geographic information -- Metadata which is the model used for spatial dataset's metadata transfer in Australia.

Usage

A dataset is the output of an activity on an entity by an agent.

Fig. 2: The level 0 conceptual model of creating a dataset.

An example:

• A company performs a survey to collect geochemical samples, observations are performed on the samples, with measurements recorded as results. The measurements (data) are compiled into a dataset that meets the requirements of the end user of the data.

Profile Resources

This profile is presented as a series of files that perform different roles:

• Guidance document - a written document explaining how to use this profile
• model - the model folder contains this profile's models in both graphical (SVG) and machine-readable, textual, form ( RDF turtle).
• imports/ - other ontologies this profile imports.
• constraints.ttl - a constraints file, formulated using SHACL, that can be used to validate instances of metadata to check conformance with this profile.
• profile.ttl - the profile declaration. A description of all of the items in this profile (the formal model, validating resources, documentation etc.) according to the W3C's Profiles Ontology which describes how all the parts related to one another, the roles they play (to give guidance for use, to validate data etc.) and how this profile profiles the various standards listed above.
