Do I need to pay any money to register for the hackathon?
No. You do not have to pay anything to anyone to register yourself for the hackathon.

Do I need to have any specific qualifications to be a participant for the Hackathon?
If you love to code or like to make user experience better, you are more than welcome to participate in the hackathon.
As this challenge is related to developing mobile based applications, a background in mobile programming will be helpful.

How do I submit what I have made for the hackathon?
You have to develop the entire software application on your local system and when you are done, send it to Wiener Linien via email as ZIP file format, along with instructions to run the application and source code. Please use this address: [email protected] . Note that this must happen before the participation phase ends!

Do we need to have the entire idea fully working?
The entire idea need not be fully implemented beforehand, however, it will be helpful to have your idea sufficiently ready, such that it can be reviewed by the judges.

How is the environment? Will your environment support any language? Will you provide any IDE or DB for us to work on ideas?
You have to develop the entire software application on your local system. No resources will be provided by Wiener Linien.

Are there any restrictions on using number of pre-built libraries?
The used technologies or libraries should be freely available.
It is possible to use licensed components, if they are available under a free plan in order to evaluate your solution.
However, relying too much on such components may affect judgement.

Do I need to give a demo for the product that I have built?
You will be required to make a video for your unique solution. You will have to upload a video (or similar presentation) to your project page of the challenge before the end of the participation phase.

A fully developed application needs to have a solid backend. How shall we do this?
For this challenge, you should use simulated data. This data can come from an "in-memory" stub, or some equivalent self-built simulator running on the same machine.

Who will own the IP(Intellectual Property) Rights to the product that I/we have built?
You will keep your intellectual property rights for what you build. You also grant Wiener Linien to use your idea and material the rights to build something upon that. Please refer to section 13 "Intellectual Property" of the legal rules for details.

Who do I reach out to if I have questions about technologies or processes?

For official answers about the business, please contact our mentors at [email protected] .

For official answers about the hackathon itself, please contact the organisation at [email protected] .

Please note that these email addresses are only monitored during office hours in central Europe timezone (Austria/Vienna), and it may take some time to receive an answer from the corresponding expert.

Do all team members have to register for the Hackathon?
Yes, all members of a team will need to register independently on TAIKAI and need to be assigned to the same project for the challenge.

During initial registration, what should I include in the project description?
Please provide a synopsis of your idea and any detail to explain the intended solution.
During the "pre-selection period" (see timeline), it will be beneficial to have more deatils to a solution in case the number of projects has to be reduced for the participation.
