This document reports implementations of the Profiles Vocabulary [[DX-PROF|PROF]].
The Profiles Vocabulary (PROF) is an RDF vocabulary created to allow the machine-readable description of profiles of specifications for information resources.
To show that PROF's constructed sensibly and that all parts of it are useful, we have collected here evidence of value, in the form of vocabulary element use (see ). The results are summarized in this report.
In this document we will employ the following namespace prefixes:
profhttp://www.w3.org/ns/dx/prof/rolehttp://www.w3.org/ns/dx/prof/role/prof:ResourceRole vocabulary
earlhttp://www.w3.org/ns/earl#We followed the steps described below to collect evidence for the use of elements of [[DX-PROF|PROF]]:
We verified the claims made by the various implementations using a test suite which is detailed in [[PROF-TESTING]].
In like with the DXWG's expectations for publication implementation evidence, as given in the DXWG charter, we have sought at least two independent implementations for every PROF element to advance PROF from a Working Group note to a Candidate Recommendation.
To verify the claims of implementations, test suite software was created. The software uses the pySHACL, an open-source [[SHACL]] validation tool, to validated RDF implementations of PROF.
The code for the test suite is stored in the following code repository location:
That repository contains notes on how to apply the test suite.
The results from applying this test suite to implementations are given in the tables in .

| I1 | The Project Ontology |
The PROJECT ontology is designed to enable publication of information describing projects, including research projects. It is not designed to support project management, though sub-activities are included. As far as possible PROJECT is intended to be domain-neutral, and it is expected that domains and applications will specialize or extend this ontology for more specific purposes. This ontology profiles [[PROV-O]]. This ontology's relationships to the things that it profiles and the relationships between its parts are described using PROF. |

| I2 | Open Data Rights Language Best Practice - Profiling |
Good practices in developing, defining and making public an ODRL Profile. This document describes how all resources - named as artifacts - which are relevant for an ODRL Profile can be described and related to one another using PROF. |

Rob to complete This collection of specifications and profiles of them, and their parts, are all described using PROF. Of particular interest is the large hierarchy of profiles created. |

| I4 | Plant Health Surveillance Ontology |
An ontology about surveillance to determine plant health, such as fruit fly trapping. This ontology's relationships to the things that it profiles and the relationships between its parts are described using PROF. |

| I6 | W3ID Profiles Catalogue |
A catalogue of profiles using the W3ID persistent URI namespace. There are multiple PROF profiles listed in this catalogue whose purpose is to provide a freely-accessible place to catalogue (list and present) any profile and also to provide profile hierarchies built from PROF RDF. |

| I7 | Commission for Geoscience Information's vocabularies |
An API delivering multiple representations of SKOS vocabularies in accordance with the [[DX-PROF-CONNEG]] specification's methods.
This system, based on the pyLDAPI too, lists the profiles according to which representations of resource may be requested. It uses [[DX-PROF-CONNEG]]'s Alternate Representations Data Model to communicate profile information in an Alternate Profiles listing for a resource. This data model uses some PROF elements, such as |

It is a requirement for W3C implementations to be independent, thus the implementations above by the same implementors are counted as a single implementation. Therefore, the independent implementation groups above are:
This section records the instances of each PROF element's use per implementation.
| Element | Implementer(s) | Location online | Notes |
|---|---|---|---|
| Class: Profile |
|
I1, I3 & I4 are straightforward instance uses of prof:Profile, I2 is the demonstrated use of prof:Profile within an example, exhorting creators of profiles of [[ODRL-VOCAB]] to use it in their instances. |

| Property: hasResource |
|
>I5's use is within a SPARQL query looks for resources from a profiles, possibly within a hierarchy, via this property. | |

I5's use is as SPARQL query that follows prof:isProfileOf path chains |

The ResourceDescriptor use by I4 is inferred from the domain entailment of the property prof:hasResource. |

| Property: hasArtifact |
|
I5's SPARQL query looks for validation files stored either locally, within a profiles repository, or remotely. | |

The PHS Ontology Profile in I4 itself conforms to the Australian Government's Ontology Profile (AGOP) which it indicates with dct:conformsTo. |
