+======Pentominos - Data Collection System ======
+=====Overview=====
+The Pentominos project consists of several sub-projects, that all work together to produce a full circle of data gathering, data storage and data retrieval.\\
+Here is a list of the current sub-projects:
+  * Artefact - The data storage server.
+  * Feed - A thin client data gathering application.
+  * Upload Server - Journal writer.
+  * Pidiod - The uid => patient ID mapper.
+  * Pidio - The uid => patient ID mapper client (numpad/rfid).
+====Patient registration====
+The system stores data. These data is connected to a patient ID, a timestamp, a location and an apparatus.\\
+Getting the patient ID is a non-trivial task at best.\\
+See the [[pentominos:registration]] section for a description of the framework surrounding the registration system.
+====RFID tag project====
+[[pentominos:rfid project]]
 ====Network communication (protocol)====
 All network communication are done via XML documents.\\

 The LUA programs hereafter sends this data to the server indirectly through a number of exposed c methods.\\
 Each LUA program must run in an infinite loop, terminating only when the function stop() returns true, and it must not hang waiting on read, but rather have a time-out, and loop again.

+====Data types====
+Problem: An apparatus produces more than one type of data, but stores all measured values in the same data block.
+How to make a query that will hit this multi-data block?\\
+Solutions:
+  * Make the validator insert one entry in the db for each data type, referring to the same data block (file).
+    * The data are only stored once in the file system.
+    * We don't need to make drastic changes to the server code (or client for that matter).
