Save and find semantic artefacts

The primary mission of an OntoPortal installation is to host and serve ontologies and semantic artefacts. The portals accept resources in multiple knowledge representation languages: OWL, RDFS, SKOS, OBO and UMLS-RRF.

Ontologies are semantically described with rich metadata (partially extracted from the source files), and a browsing user interface allows to quickly identify, with faceted search, the ontologies of interest based on their metadata.

Browse the content of semantic artefacts

OntoPortal lets users visualize a class/concept or property within its hierarchy, as well as see related information for this entity (as relations included in the source file).

Search for terms

All the semantic artefacts content hosted in an OntoPortal is indexed and can easily be retrieved.

Much more available as standard OntoPortal services...

Custom hosting

Organize public/private ontologies, group/categorize them and offers custom slices.
Versioning

Store all ontology versions, whether manually submitted or automatically pulled. Get diff between versions.
Widgets

Easily embed Web widgets in external web applications to facilitate the reuse/visualization of ontology entities.
Mappings

Store, retrieve and explore mappings between ontology terms. Get lexical overlap of an ontology with all the other ones in a portal.
Community

Get notified from feedback as notes, change requests and record projects using ontologies.
Annotator

Identify semantic artefact classes or concepts inside any raw text.
Recommender

Get ontology recommendations for a provided text or keyword list.
Automated access

Access all content and services with two different endpoints: a REST web service API that returns JSON-LD and a SPARQL endpoint.
Standard ontology metadata model

Standardized and harmonized metadata model based on MOD1.4 to better support descriptions of ontologies and their relations.
Extended SKOS support

Full support of SKOS and innovative browsing approaches to discover and navigate concepts in SKOS thesauri that make extensive use of scheme and collections.
Multilingual support

Full support (search and browsing) of multilingual content within ontologies.
Generic Triple Store Backend

Store and query ontology data through standards RDF triple store backend (4store, AllegroGraph, Virtuoso, GraphDB) for maximum scalability and interoperability.

And even more additional features and services developed by the Alliance...

Enhanced mapping features

New visualization and more flexible mapping storage, import mappings in bulk or extract SKOS mappings explicitly defined in semantic artefact source files.
Enhanced semantic annotation workflow

Natural language-based enhancements of the Annotator with scoring methods context detection (e.g., negation, temporality).
Semantic artefact FAIRness assessment

Get FAIR score for each semantic artefact from 61 questions implemented from the Ontology FAIRness Evaluation (O’FAIRe) methodology.
Assigning DOIs

Request a Digital Object Identifier (DOI) for resources hosted in the portal using Datacite services.
New user interfaces

Easy-to-use modern and respnsive user interfaces.
URIs dereferencing

Easy-to-use infratructure supporting ontology URI dereferencing (resolutuon and content negociation).
Agents profiling

Search, browse, and manage agents (persons and organizations) associated to ontologies and see their complete profiles.
Related projects

Rewamped ontology related project functionalities inclduing connectors to funded project databases.
MOD-API support

Full (level 4) MOD-API (v1) implementation for enhanced interoperability with other Semantic Artefact Catalogues.
Federation

Harmonized search and discoveries of ontologies accross multiple federated OntoPortals.
Change requests

Suggest ontology content changes (new terms, synonyms, definitions) direclty from OntoPortal to GitHub.
Authentication & SSO

Integrate with LDAP or OAuth2 for unified access management.

What Users Say

I rely on BioPortal for easy access to SNOMED and a number of other terminologies, particularly for when I just want to check the existence of specific terms. I love having a one-stop shop to find just about any ontology I might need.

Jessie Tenenbaum - Duke University

The TSCF lab from INRAE uses AgroPortal to share and promote its RDF semantic resources related to agriculture: the French Crop Usage Thesaurus, BBCH-based Plant Phenological Description Ontology (PPDO), and more.... We love the FAIRness evaluation service, O'FAIRe.

Catherine Roussey - INRAE, MISTEA lab

I’m using BioPortal to browse and search different ontologies and vocabularies such as NDF-RT and SNOMED CT. I find codes for terms and restrictions on terms and I then copy them into clinical guideline representations so that I can use standard terminologies.

Mor Peleg - University of Haifa

The BioPortal is a referential and invaluable ressource for our research group. We use the BioPortal daily to browse medical ontologies, evaluate how they cover clinical data and could be used to structure and normalise them.

Adrien Coulet - Inria Paris, HeKA team

I am using AgroPortal to get a public access, regularly updated, to the LEXEAU ontology a bilingual water lexicon (...) which aim is a better intercomprehension of the water issues by the public and private stakeholders. The integration in AgroPortal and the alignements of LEXEAU with other ontologies facilitate the international dissemination and further realization of the project.
