The DCAT-AP conversion to a LinkML Schema is the intended point of truth for the DCAT-AP+ schema, but could be used alternatively as a LinkML representation of DCAT-AP for other Projects. It is a port of DCAT-AP to the LinkML world that is as faithful to the original as possible. This Persistent Identifier does not only provide the SHACL Shape, but could also be used as described [here](https://github.com/perma-id/w3id.org/tree/cecbc2e5f40d928f05ed5306d24fc60db0e7bb21/nfdi-de/dcat-ap-plus). DCAT-AP+ is a [LinkML](https://linkml.io/)-based extension of the [DCAT Application Profile 3.0](https://semiceu.github.io/DCAT-AP/releases/3.0.0/) that adds a provenance layer for describing how a dataset was generated and what it is about, using the [Starting Point Terms of PROV-O](https://www.w3.org/TR/prov-o/#description-starting-point-terms), the [QUDT ontology](https://www.qudt.org/), and [Dublin Core Terms](http://purl.org/dc/terms/).

The System Package Data Exchange™ (SPDX®) specification is an open standard designed to represent systems containing software components as Software Bill of Materials (SBOMs). Additionally, SPDX supports AI, data, and security references, making it suitable for a wide range of risk management use cases. This _spdx3_ prefix is for SPDX 3.x versions. For earlier versions, use _spdx.term_.

An extension of Schema.org to annotate metadata on software projects

This is the Provenance Information for Materials Science (PRIMA) Ontology, version 3.0, aligned with PMDco v3 and based on BFO (Basic Formal Ontology). This complete module imports all PRIMA modules (core, data-analysis-lifecycle, dataset, experiment, and computational) in their v3.0 versions.

The submission-centric metadata schema for the German Human Genome-Phenome Archive (GHGA).

Bioschemas aims to improve the Findability on the Web of life sciences resources such as datasets, software, and training materials. It does this by encouraging people in the life sciences to use Schema.org markup in their websites so that they are indexable by search engines and other services. Bioschemas encourages the consistent use of markup to ease the consumption of the contained markup across many sites. This structured information then makes it easier to discover, collate, and analyse distributed resources. [from BioSchemas.org]

The OntoUML Metamodel repository contains the metamodel of the OntoUML language. Unlike the UML profile, this version is independent of UML and presents only the concepts officially supported in the language. This metamodel covers the abstract and concrete syntaxes of the language and serves as the reference for all projects in the OntoUML as a Service (OaaS) ecosystem, including its different model serializations. [from https://github.com/OntoUML/ontouml-metamodel]

DCAT-AP is a DCAT profile for sharing information about Catalogues containing Datasets and Data Services descriptions in Europe, under maintenance by the SEMIC action, Interoperable Europe. This Application Profile provides a minimal common basis within Europe to share Datasets and Data Services cross-border and cross-domain. [from homepage]

EPOS-DCAT-AP is an extension of the DCAT Application Profile for Research Infrastructures in Environmental and the solid-Earth domains.

An OWL 2 DL ontology developed for creating sets, bags and lists of resources, and for inferring collection properties even in the presence of incomplete information.

Schema for the export of the Bioregistry as RDF

This ontology describes the RDF representation of the contents of the dblp computer science bibliography.

The aim of lemon is to provide rich linguistic grounding for ontologies. Rich linguistic grounding includes the representation of morphological and syntactic properties of lexical entries as well as the syntax-semantics interface, i.e. the meaning of these lexical entries with respect to an ontology or vocabulary. [homepage]

Overview of the Web Ontology Language (OWL) which provides an introduction to OWL by informally describing the features of each of the sublanguages.

This is the experiment module of the Provenance Information for Materials Science (PRIMA) Ontology, version 3.0, aligned with PMDco v3 and based on BFO (Basic Formal Ontology). [from homepage]

RDF Schema provides a data-modelling vocabulary for RDF data. RDF Schema is an extension of the basic RDF vocabulary.

A dictionary of named properties and classes for Software Package Data Exchange (SPDX) - an open standard for communicating software bill of material information, including components, licenses, copyrights, and security references. SPDX reduces redundant work by providing a common format for companies and communities to share important data, thereby streamlining and improving compliance. [from homepage]

The Swiss Personalized Health Network is a national infrastructure initiative with the aim to develop, implement, and validate coordinated data infrastructures in order to make health-relevant data interoperable and shareable for research in Switzerland. The sphn RDF schema builds the foundation for all data exchanges within the sphn by integrating semantic information defined in the [sphn dataset](https://sphn.ch/document/sphn-dataset/).

VOAF is a vocabulary specification providing elements allowing the description of vocabularies (RDFS vocabularies or OWL ontologies) used in the Linked Data Cloud. In particular it provides properties expressing the different ways such vocabularies can rely on, extend, specify, annotate or otherwise link to each other. It relies itself on Dublin Core and voiD. The name of the vocabulary makes an explicit reference to FOAF because VOAF can be used to define networks of vocabularies in a way similar to the one FOAF is used to define networks of people.

This document describes the XML Schema namespace. It also contains a directory of links to these related resources, using Resource Directory Description Language.

The GESIS Knowledge Graph Ontology is used to build the GESIS Knowledge Graph (GESIS KG) which provides a FAIR-compliant semantic representation of scholarly metadata from the social sciences available in the GESIS Search.

A schema representing publication metadata

An RDF Schema that can be used to attach constraints and rules to RDFS classes, and to encapsulate reusable SPARQL queries into functions and templates.
