Open Data : help organizations to open their data on the web

Make data available to your partners, customers, users and use external data available on the web.

Why start working with open data?



The biggest feature of this technology is for Open Data needs, mainly driven by institutions, to make data available to citizens. But this technology can also be used in the corporate world internally as repositories, externally to display data for partners or harvested/consumed as third-party data

Making public data available and accessible for use on the web



In line with the W3C’s “web of data” method, we rely on the standards and tools of the semantic web to display structured data in a standardised, interoperable format that can be used automatically by machines.

Coexya proposes a proven methodology for publishing structured data on the web

We analyze the business domain and design an ontological model, reusing standardized vocabularies. We transform the data into RDF format to expose them in a public way, in the respect of best practices via warehouses providing technical query interfaces (sparq enpoint)  or by making them more user friendly.

These solutions are particularly popular in the legislative (open law), cultural and health fields, and by public institutions and organizations that disseminate information to citizens.

Knowledge modeling

• Creation / use of repositories,
• Content aggregation,
• Reasoning: Inference and deduction,
• Distribution in an easily understandable / integrable format,
• SHACL validation of data.

Semantic Web 

• Provision of data in standard Open Data format,
• Enrichment with external data exposed in warehouses available on the web.

 Coexya is a major player in the web of public data for several years



We are proud to partner with many public institutions in the implementation of their open data projects, such as the Ministry of Higher Education, Research and Innovation, the National Institute of Art History or the Digital Health Agency.
