As part of the protocol there will be developed basic set of formats defined across a variety of data types. These formats should be included in the standard catalog node “XBUP Project”, which is managed along the basic protocol and is intended primarily for testing the principles of the Protocol.

Individual formats can be classified according to various criteria.

This classification is defined to encompass the various fields of scientific areas.

• Mathematics
• Physics
• Chemistry
• Biology
• Information Technology
• Social Sciences (sociology, philosophy, psychology and language sciences)

Groups of formats belongs to different category depending on which particular receptor is able to process them.

• Eyesight (visual)
• Hearing (sound)
• Touch/tactile/pressure (haptic)
• Smell
• Taste
• Balance and acceleration
• Temperature

Other relative categories can be for example general pain or electricity perception, brain activity level and other physical sensations and states (thirst, hunger, fear…).

It is also possible to differentiate formats according to areas of human activity:

• Business and Finance
• Production
• Mining and production of raw materials
• Services
• Transport
• Research and development
• Health care
• Social Services
• Government
• Military

Many representations of data items exceeds the above categorization, for example:

• Text (meaning, graphic design, pronunciation)
• Model (physical meaning, graphic design)
