For this purpose, DASF defines a remote procedure call (RPC) messaging protocol that uses a central message broker instance. Scientists can augment their tools and data with this protocol to share them with others or re-use them in different contexts. ## Language support The DASF RPC messaging protocol is based on JSON and uses Websockets for the underlying data exchange. Therefore the DASF RPC messaging protocol in general is language agnostic, so all languages with Websocket support can be utilized. As a start DASF provides two ready-to-use language bindings for the messaging protocol, one for Python and one for the Typescript programming language. ## Needed infrastructure DASF distributes messages via a central message broker. Currently we support a self-developed message broker called [dasf-broker-django](https://gitlab.hzdr.de/hcdc/django/dasf-broker-django), as well as an 'off-the-shelf' solution called [Apache Pulsar](https://pulsar.apache.org/). Both are quite versatile and highly configurable depending on your requirements.
