Validate Metadata

Verify the syntax, structure, and semantic annotations of OMEX metadata files across 5 serializations against BioSimulations publishing guidelines and W3C RDF standards.

Metadata Conventions

Input Source & Settings

Select a local file or provide a public URL to validate.

Metadata Format Format Specs

XML serialization of RDF graphs. Standard format required for publishing project metadata to BioSimulations.

Extensions:.xml.rdf.rdfxml

Validation Schema Schema Guide

BioSimulations Schema (Recommended)

Enforces BioSimulations conventions and minimal metadata requirements (title, creators, description, license) needed to publish projects.

RDF Triples (General Semantic)

Validates standard RDF graph syntax and ontology triples without domain-specific BioSimulations publishing restrictions.

Single-File Validation & Project Scope:

Although metadata can be described across multiple OMEX Metadata files, this utility validates an individual metadata file. If your project splits metadata across files or references thumbnail image files, validate the entire archive with the Validate COMBINE Project utility.

File uploads are limited to 64 MB (files up to 1 GB can be submitted via URL). Sample metadata files are available in the BioSimulators test suite examples .

Local & CI/CD Validation

Validate your RDF/XML metadata annotations locally using the biosimulators-utils CLI.

biosimulators-utils validate-metadata path/to/metadata.xml --format rdfxml --schema BioSimulations

Required Properties for Publishing

To publish simulation projects to the BioSimulations repository, OMEX metadata documents must satisfy minimal metadata requirements:

Title & Abstract: Concise project title (dc:title) and detailed summary (dc:description).

Creators & Attribution: Names and ORCID persistent identifiers for authors and model curators (dc:creator).

Open License: SPDX identifier or URI granting terms of reuse (e.g. CC0, MIT, CC-BY) (schema:license).

Publication Citations: Articles describing the model via PubMed, DOI, or EuropePMC identifiers (bqmodel:isDescribedBy).

COMBINE Metadata Ecosystem

OMEX Metadata follows the recommendations of the COMBINE community and is parsed using the libOmexMeta library.
