+======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:
+  * [[pentominos:Artefact]] - The data storage server.
+  * [[pentominos: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).
+====LUA elements====
+  LUADataValidator
+  LUADataParser
+====Snaask====
+When an apparatus is connected the following must be crafted:
+  * Feed parser so file and conf.
+  * Artefact validator / identifier.
+    * Makes superficial parsing of the data to identify whether the data is valid.
+    * Figure out what classes are contained in the data, and report this.
+  * Artefact interpretation
+    * Parses and interprets the data, translating it into some output language (eg. xml)
+(data, class) => [lua] Parser -> [lua] Interpretation -> [lua/c] Tree structure -> [c] language filter -> network
+====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.

+[[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.

 How to make a query that will hit this multi-data block?\\
 Solutions:
-  * Make client send data one time pr. data type, thus storing it in the db under two different classes.
-    * //Pros//:
-      * We don't need to make any changes to the server code.
-    * //Cons://
-      * The client needs to parse the data (no longer thin).
-      * The data are stored multiple times in the file system.
-  * Make validator detects which types of data are contained in the block, adding a list of type tags in the database.
-    * //Pros://
-      * The data are only stored once in the file system.
-    * //Cons://
-      * Needs to query an entry in a list in the db.
   * Make the validator insert one entry in the db for each data type, referring to the same data block (file).
-    * //Pros://
+    * The data are only stored once in the file system.
-      * 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).
