    * Timestamp: time at which message was injected (Unix time in seconds since 1.1.1970). Precision goes to the microsecond.
    * Hostname: the name of the machine where the message is issued. For concision, the domain name is excluded from this tag, only the base IP host name is kept.
    * Rolename: the role name associated to the entity running the process. The same host might run several different roles. Example role name: FLP-TPC-1, EPN-223.

    The initial list of fields has been taken from the Run 2 vocabulary. It may be adapted, in particular depending on the implementation and naming conventions of the control system.
 
    The fields are grouped in different categories.

     Usually, one will only take care of defining the per-message messageOptions struct and a context with appropriate Facility field set, all other being set automatically.
+
+ * On the server side, messages are stored in a database, consisting of a single "messages" table (and possibly some archived versions of this table).
+   The reference for the data structure is the table description itself, with one column per message tag, trivially matching the list of tags described above.
+   Fields which are undefined appear as NULL (unless the library automatically sets a value for them).
+   String fields usually have a maximum size (and are truncated if exceeding this limit, typically 32 characters).
 
  * InfoLogger library is also available for: Tcl, Python, Go, Node.js.
    It allows to log message from scripting languages. A simplified subset of the InfoLogger C++ API is made available through SWIG-generated modules.
