Abstract: New users at a synchrotron facility like PETRA III are often overwhelmed by the multitude of possible experimental techniques (ETs) and their many variations with respect to energy ranges as well as sample and sample environment characteristics (e.g. crystalline and liquid samples; different in-situ setups). In order to help inexperienced users find an optimal beamline for their scientific questions, we are working on composing the capabilities of the PaNET ontology (Photon and Neutron ETs) with the web framework of the overview platform Way For Light (WFL). While WFL already offers a wealth of information for the more experienced users to explore the light sources in Europe, it currently does not cover the sample environment information and also only has a very rough categorization of the ETs. In contrast, the PaNET ontology lists more than 300 techniques that are (partially) interrelated and also reveal the purpose of the technique (e.g. creation of a 3D spatial map).By creating a web page that asks the right, intuitive questions, we aim to guide new users to find the perfect beamline for their experiments. Currently, we are creating a proof-of-concept that uses a functional programming language with a reactive paradigm (Elm) to query an underlying SPARQL endpoint. This endpoint includes the PaNET ontology as well as a customized database on the PETRA III beamlines. Using the customized database instead of WFL for now allows us to also include basic information on the available sample environments and to explore different approaches in handling dependencies between various experimental setups. The created web page provides users with an interactive way to navigate through the different options. This serves as a prototype for future work, a demonstration of the feasibility of the approach, and an opportunity to receive feedback from experts and users.
