List of Data to be monitored in the system.
Ver. 0.1 – 19 October 2004

This list of data is needed to construct a model of the ‘context’ in which the communication takes place. Essentially, we are interested in understanding how the peers of the communication ground their communication and how the inference takes place.

These informative tag should be attached by the system to the record of the message and stored in the general DataBase.

1- time of MSG
The time when the message was sent.

2- position of content (x,y)
The intended position of the message. If different from the current position, the position of the emitter at the moment of postion should also be logged.

3- position of the emitter, receiver at the moment of posting
The position of the emitter and the receiver, if any while the message was posted.

4- content of the MSG
The content of the message should be organised in a databese.

5- history of the emitter, receiver (previous, current and future position)
The span of interest for the connected activities of the message should last longer than the moment of posting.

6- Activities of emitter and receiver (as assumed from their pre-defined position)
There should be some position pre-defined in the system, like the office place, home, school, etc. From that an assumption of the connected activity in that place.

7- emitter inputed categories
Some generic categories can be added to the message from the emitter, espetially if the message is sent to the larger group. Eventually, we may think these categories as socially defined by the group and rated.

8- friend of a friend chain
The FOAF description of the emitter, receiver chain.

9- social editing/rating of the message
The acknowledge of the reactions of the other readers to the message, if this is not private.

10- shape of the buildings and other geographical objects on the way
Important landmarks socially defined by the users which happen to be along the way or close to the message anchor point (AP).

11- thread of the message
The chain of the messages answered to the main. Time and history should be connected as the main.

12- acknowledge of retreive of the message
The acknowledge of the retrieve of the message by the receiver or the receivers.
