Professional FHIR Server
Vonk is an enterprise-grade FHIR Server meant for production environments large and small alike. Vonk is designed and built from the ground up, using our extensive experience with the FHIR specification, Microsoft .Net programming and Vonk’s predecessor Spark. We have a free edition for testing and educational purposes and a licensed version with support.
There is always a Vonk that fits your needs
Vonk is available in different distributions. Vonk FHIR Server is an integrated, turn-key FHIR server that runs on its own storage. Vonk FHIR Facade enables you to open up legacy systems to the FHIR ecosystem, leaving the FHIR heavy lifting to us. Vonk FHIR Components (“Build Your Own FHIR Server”) is a set of NuGet packages that allows you to build a highly customized version of Vonk, or integrate FHIR Server operations in your own application.
You can try Vonk FHIR Server in different ways. Visit http://vonk.furore.com to access the public FHIR endpoint hosted by Vonk. Or go to http://docs.simplifier.net/vonk to see how you can download and run your own Vonk FHIR Server for evaluation.
No matter which distribution of Vonk you intend to use, it comes with a pack of features. Most of these features refer to operations in the FHIR RESTful API as defined in the FHIR Specification. Vonk implements FHIR version STU3, in both JSON and XML formats. DSTU2 support is also possible. It can handle all resource types, including profiled resources, except for Binary. The current beta version already supports most of the interactions.
- capability statement (metadata)
- read, create, update, delete
- search on all searchparameters defined in the specification
- chained parameters and choices
- search on multiple resource types (“_type”)
- unification of quantities
- history (instance, type & system)
- batch and transaction (only on a database engine that supports transactions)
- validation of a resource against the core specification or a custom profile
- snapshot generation
- extensible with custom operations (“$<your-operation>”)
- support for several more options, e.g. _summary, _elements
- custom search parameters
More features are on their way. Priority is volatile and can be influenced by customer requests. Features on the roadmap include:
- documents ($document)
- resource type ‘Binary’
Vonk can run natively on SQL Server, MongoDB and an in-memory storage. Support for other database engines can easily be added. Vonk FHIR Facade and Vonk Components allow you to connect Vonk to existing databases.
- Authentication with an OAuth token against a seperate OAuth identity provider
- Authorization based on Smart-on-FHIR scopes and launch context
- Extensible system for adding custom authorization or scoping of a request to a subset of the data
- Https support
There is a wide variety of deployment options for Vonk.
- Binaries with a very simple installation procedure
- Docker images
- Azure App Service
- Cross platform (Windows, Linux, OS-X)
- Flexible logging
- Can be connected to Microsoft Application Insights
- Add profiles, or restrict to specific profiles
- Add or restrict the search parameters
- Enable or disable operations
Vonk FHIR Server is built with Microsoft ASP.Net Core, which enables cross-platform support and fully self-contained binaries (no pre-installed .Net Framework required). It runs on Kestrel, a very fast web server that is highly integrated with ASP.Net Core. And of course it utilizes our own HL7.Fhir API.
What happens to Spark?
This is up to the community. Furore has put a lot of effort in Spark and provides all of this effort to the community. It’s open source, available on GitHub. But Furore will neither port Spark to STU3 nor provide support for DSTU2.
