Campus Party is an annual technology festival for young people with talks, debates, workshops, competitions and hackathons related to science, innovation, digital entertainment and creativity.

The event takes place from 2-7 September 2013 and ebbits is sponsoring a hackathon from 3rd to 5th September - a fast event where developers can create a new mobile application in less than 48 hours.

An XML-file with data is provided as data source together with a website with documentation and background info. ebbits partners provide support throughout the runtime of the challenge.

The challenge is to provide a mobile food traceability application which involves at least two stakeholders and which is placed in the following Internet of Things setting:

Traceability is a crucial factor in ensuring that the food we eat is of high standard in terms of quality and safety. The foundation for all food traceability systems is the unique identification and registration of all food sites or premises along the supply chain, in general involving three elements: premises identification, product identification and movement recording. All information is exchanged via dedicated web services, which collect the relevant data from national servers, business ERP systems and local farm computers. These exchanges are made without compromising the integrity and security of sensitive business data.

Traceability along the food supply chain is basically the combination of two processes: intra-enterprise traceability and inter-enterprise traceability. For this to be feasible it is necessary to adopt common data references at enterprise level to describe e.g. crop protection chemicals, implements, interventions, analysis, etc. in a consistent way. Traceability at inter-enterprise level will be inexorably linked to logistics and hence depending on having a common, precise identification of all products.

The players in the farm environment are the feedstuff suppliers, whose main interest is in ensuring that all ingredients and their composition are documented, and the farmers, who are interested in correlating the obtained output with ingredients used, breed of animals, environmental conditions, etc. to ensure maximum outcome. Because of the exchange of information feedstuff manufacturers and farmers can react very quickly on emerging trends in animal responses to variations in their feed. Likewise data can be exchanged between slaughterhouses and farmers to correlate individual animal development with projected consumer demands and promotion campaigns.

The processing environment includes slaughterhouses and processing and packaging companies whose interests are often similar, namely to link data for the whole animal to each individual cut in order to maintain traceability.

The distribution environment involves wholesalers and transporters, whose main interest is the same: to demonstrate an unbroken cold chain.

The stakeholders in the consumer environment are retailers, for whom an important objective is to build a trust relationship with his customers, and the consumers whose main interests typically are quality and price. The consumer has access to detailed information relating to the history and quality of purchased products, e.g. origin, animal breed, feedstuff characteristics, medical treatment, etc. This is particularly relevant for ecological and other special-brand foods.
