The purpose of this page is to describe the motivations and requirements for ANZGeoDCAT and this page is being written before ANZGeoDCAT is created to ensure it best caters for a wide range of agreed to requirements.

ANZGeoDCAT will be a profile of Data Catalog Vocabulary (DCAT) and also of GeoDCAT which is, itself a profile of DCAT.
The Profile’s formal definition is at:
There are several main motivations for the creation of this Profile:
-
to provide a Knowledge Graph / Semantic Web metadata standard for several new, Australian & New Zealand, geospatial agencies' spatial data catalogues
-
several agencies are implementing new CKAN instances and CKAN can already export some DCAT metadata. Let’s improve that…
-
-
to ensure geospatial metadata works well with currently emerging non-spatial KG metadata standards
-
in particular the already formulated Indigenous Data Network Catalogue Profile
-
perhaps the DCAT-like Office of the National Data Commissioner (ONDC) Core Metadata Attributes
-
-
to ensure Semantic Web geospatial metadata is as interoperable as possible with established non-Semantic Web geospatial metadata standards
-
in particular the GA profile of ISO19115-1
-
-
to show Best Practice metadata profile creation
-
the Australian geospatial community has a long history with metadata standards and brings considerable experience to profile creation, so we think this represents Best Practice profile creation in Australia & New Zealand
-
the W3C’s Profiles Vocabulary is the standard’s body’s best effort to provide a standardised profile description model, so ANZGeoDCAT will use that for its definition
-
-
to present Australian & New Zealand geospatial metadata profile requirements for international profile efforts
-
the Open Geospatial Consortium is starting a standardisation initiative around Knowledge Graph geospatial metadata with their formalisation of GeoDCAT and we want to be part of that with our requirements already formulated
-
Requirements for ANZGeoDCAT as a whole - not the individual requirements for metadata elements as will eventually be specified by the profile - are being gathered in this repository as Issues and progress is tracked via and Project Issue Tracker. Initial Issues, as of December 2022, are also listed in the table below.
| ID | Name | Description | Rational | Proponent |
|---|---|---|---|---|
Formal Profile |
ANZGeoDCAT will be presented as a formally defined Semantic Web profile of DCAT and other standards, formulated according to the W3C’s [Profiles Vocabulary](https://www.w3.org/TR/dx-prof/). |
ANZGeoDCAT will both utilise the though behind formal profile definition and showcase it for other potential profiles. |
ICSM, GA |
|
Two-way mapping to the ICSM ISO 19115-1 Metadata Profile |
ANZGeoDCAT data will need to be able to converted to ICSM ISO 19115-1 Metadata Profile data, which is non-Semantic Web XML data, and vice-versa |
ANZGeoDCAT is aiming to be a Semantic Web equivalent to ICSM ISO 19115-1 Metadata, so a demonstrable (executable) both-ways mapping must be maintained. |
ICSM, GA, GSSA |
|
Interoperability with the Indigenous Data Network’s Catlogue Profile |
ANZGeoDCAT must be able to work with the IDN CP so that indigenous spatial data can be made conformant to both |
Indigeneity and spatiality are different, specialised but potentially overlapping aspects of data and there are dataset known to have both dimensions |
Indigenous Data Network |
|
Conformance with OGC GeoDCAT |
Eventual alignment with the results of the OGC's current GeoDCAT-AP standardisation effort |
ANZGeoDCAT must be conformance with similar international standards, when they are established |
ICSM, GA |
|
Mapping to schema.org |
Mapping of metadata elements to the general-purpose Knolwedge Graph model schema.org |
Search Engine optimisation |
KurrawongAI |
|
Mapping to FAIR scores |
Calculation of FAIR Scores from ANZGeoDCAT metadata must be possible |
To allow for the use of the widely-known FAIR score as a metric for ANZGeoDCAT datasets |
Indigenous Data Network, GSSA, GSWA |
|
Linking to Semantic Web spatial data |
ANZGeoDCAT metadata, if created for a Dataset that has content in Semantic Web form, must be able to indicate this data and describe it in summary |
Australia already has published spatial datasets using DCAT that have their content published in Semantic Web form, e.g. the FSDF’s Linked Data form of the ASGS, and they should be handled well by this profile |
GA |
The Profile will be a formal (model-defined) profile of DCAT using profile modelling semantics taken from the W3C’s Profiles Vocabulary.
The Profile will likely define constraints on the use of DCAT, mappings from DCAT to other models, suggestions/requirements for the use of models related to DCAT, like PROV for provenance, and interfaces with other profiles, such as the Indigenous Data Network’s Catalogue Profile.
The Profile will be presented in normative, human-readable form (a specification), machine-readable model form (a model/schema) as well as mappings, supporting vocabularies and so on. Tooling for data validation against the Profile and for metric calculation from Profile data (e.g. FAIR scores) will also be provided.
Anyone can get involved with the development of ANZGeoDCAT and we encourage anyone with an interest in this space to participate. Please just contact those listed below to let us know.

Coordination and technical establishment |

This Profile is being established for the organisations already involved with coordination and technical work resourced by them.
Eventual governance and ownership of this Profile will be determined by the participating organisation but will likely be allocated to perhaps one of the following:
-
an Australia & New Zealand spatial consortium - e.g. ANZLIC / ICSM
-
a lead agency - e.g. Geoscience Australia
-
an informal group of agencies - those participating
