in that question you are required to provide an overall technical description of how your experiment interact with Organicity. One experiment may be something as simple as a mobile application feeding data into Organicity or something more complex with legacy middleware in which the information goes through a local (experiment) server and then inject treated/aggregated data into Organicity. The options are countless and each experiment will be different.
The Organicity components are any API or tool that you will use. You can find them all in the technical documentation. It is not necessary a very detailed explanation, but enough information for us to check that what you want to use can be actually done.
