Field Notebookc back to ToC or Class ToC

IRI: http://pid.geoscience.org.au/def/ont/ga/pdm#FieldNotebook

A digital version of a hard-copy field notebook recorded by geologists or other field scientists. GA has lots of different collections of field notebooks from Australia, Antarctica and elsewhere. GA's field notebooks typically link to Samples, Imagery and sometimes Datasets.

Ontologyc back to ToC or Class ToC

IRI: http://pid.geoscience.org.au/def/ont/ga/pdm#Ontology

An ontology is "a formal naming and definition of the types, properties, and interrelationships of the entities that really or fundamentally exist for a particular domain of discourse" (Wikipedia: https://en.wikipedia.org/wiki/Ontology_(information_science)).

Ontologies listed in this PDM are Web Ontology Language (OWL) ontologies delivered by GA for various purposes, for example the LINK ontology which presentes the data model used by the LINK Content Management System (http://link.fsdf.org.au) as a formal OWL ontology at http://pid.geoscience.gov.au/def/ont/link.

All GA's ontologies are listed within GA's ontology register at http://pid.geoscience.gov.au/def/ont/.

Samplec back to ToC or Class ToC

IRI: http://pid.geoscience.org.au/def/ont/ga/pdm#Sample

GA is the custodian of several millions of rock, gem fossile oil and other types of geoscience-relevant samples.

Metadata for GA's samples are delivered via the Samples Register: http://pid.geoscience.gov.au/sample/.

GA defines its Samples as subclasses of the SOSA ontology's Sample class as well as PROV's Entity.

Sitec back to ToC or Class ToC

IRI: http://pid.geoscience.org.au/def/ont/ga/pdm#Site

GA maintains a Sites table in the central Oracle database, A Schema, that contain thei individual Sites that GA publishes via a Linked Data API at http://pid.geoscience.gov.au/site/.

The metadata about these Sites contained in A Schema is not the totality of information known about each Site by GA but the information contained is enough for geographic positioning of the site and to associate other GA publised items with, such as Samples.

Sites can be of many different types such as boreholes, survey areas, transects and so on. The details of GA's Sites will be published through this ontology over time.

Software Repositoryc back to ToC or Class ToC

IRI: http://pid.geoscience.org.au/def/ont/ga/pdm#SoftwareRepository

A Software Repository is an instance of a version contol system such as Git, usually managed by a dedicated online service such as GitHub or BitBucket that stores and manages software code.

A Software Repository is also a type of dataset therefore GA's Software Repositories are listed in one of GA's registers, just as all datasets are.

Surveyc back to ToC or Class ToC

IRI: http://pid.geoscience.org.au/def/ont/ga/pdm#Survey

A Survey is an activity undertaken by GA or someone on GA's behalf to aquire data. Common Surveys conducted by/for GA include airborne geophysical surveys, ship-borne bathymetry surveys and on ground passive seismic surveys.

Information about Surveys in GA is delivered online via GA's Surveys Register: http://pid.geoscience.gov.au/survey/ from our internal database systems. Individual Surveys URIs, e.g. http://pid.geoscience.gov.au/survey/801, are quoted in dataset's metadata in order to indicate which survey generated a paticular dataset.

In recognition of Surveys being one-time temporal events, they are modelled mainly as a type of prov:Activity. This enables the relationship of prov:wasGeneratedBy to be used to associate the dataset(s) produced by an activity with it. It also allows the Survey to be associated with a range of prov:Agents who may have played a role in conducting the Survey via the typical Agent/Acitivty relationships available in PROV.

Vocabularyc back to ToC or Class ToC

IRI: http://pid.geoscience.org.au/def/ont/ga/pdm#Vocabulary

GA uses vocabularties to deliver the relationships between terms within particular domains.

GA publishes domains via our vocabulary register: http://pid.geoscience.gov.au/def/voc/

A Vocabulary, as published by GA, is both a SKOS ConceptScheme and also a DCAT Dataset. This means its content is in accordance with SKOS but its metadata is in accordance with DCAT.

Web Servicec back to ToC or Class ToC

IRI: http://pid.geoscience.org.au/def/ont/ga/pdm#WebService

GA's Web Services are a specialised type of a dataset distribution: they are a services that allow for dataset subsetting (querying) and supersetting (merging data from multiple datasets).

GA has an extensive catalogue of Open Geospatial Consortium web services but also has a few non-OGC web services, such as bespoke RESTful APIs, database XML APIs and SPARQL endpoints.

GA's main register of Web Services is delivered via its main enterprise catalogue eCat at http://ecat.ga.gov.au.

Object Properties

is sample ofop back to ToC or Object Property ToC

IRI: http://www.w3.org/ns/sosa/isSampleOf

GA's relation between Samples and Sites is one of isSampleOf which is the property from the SOSa ontology used to relate Samples of something to the thing which could be another Sample. So GA's Sites are inferred to be a type of Sample (of a FeatureOfIterest, like the lithosphere).

IRI: http://pid.geoscience.org.au/def/ont/ga/pdm#operatesOn

Web Services operate on Dataset(s).

This is a restricted version of the inverse of DCAT's distribution property and is a code list value in ISO19115-3.

was generated using planop back to ToC or Object Property ToC

IRI: http://pid.geoscience.org.au/def/ont/pdm#wasGeneratedUsingPlan

Entities may have been generated from Plans (instructions or code).

Use of this property as per :DatasetX wasGeneratedUsingPlan :PlanY is equivalent to declaring:

:DatasetX a prov:Entity ; prov:wasGeneratedBy [ a prov:Activity [ prov:qualifiedAssociation [ prov:Association [ prov:hadPlan :PlanY ]]] .
