EcoPortal is a repository for semantic artefacts that pertain to Ecology and Biodiversity. It hosts relevant ontologies and controlled vocabularies together with their metadata and it offers a suite of tools to discover, publish or utilise them.

The F2DS is a unifying data space that is built by aggregating and enriching datasets from a set of multidisciplinary repositories, i.e. data sources, with the aim to facilitate data discovery and reuse. Although datasets are the primary focus of the resulting data space, other items are managed, including repositories and data sources, APIs, metadata schemas and ontologies

The Repository Finder is a searchable registry of repositories with embedded content and metadata.

AgroPortal is an ontology repository (more generally a semantic artefact catalogue) for the agri-food domain which features ontology hosting, search, versioning, visualization, comment, and recommendation; enables semantic annotation; stores and exploits ontology alignments; and enables interoperation with the semantic web.

VocBench is a web-based, multilingual, collaborative development platform for managing and sharing reference data, controlled lists of codes and terms, thesauri and ontologies, used to organise information

RO-Crate has been established as a community effort to practically achieve FAIR packaging of research objects (digital objects like data, methods, software, etc.) with their structured metadata.

O'FAIRe (Ontology FAIRness Evaluator) is a metadata-based automatic FAIRness assessment methodology for ontologies and semantic artefacts.

Best practices for implementing FAIR vocabularies and ontologies on the web is a set of guidelines for ontology/vocabulary development and publishing.

Linked Open Vocabularies (LOV) is an ontology search and reuse tool designed to help publishers and users of linked data and vocabularies to assess what is available and facilitate reuse.

Widoco is an ontology documentation tool that allows users to publish and create a customized documentation for an ontology automatically by following a series of steps in a GUI.
