+ Configuring &appname;
+
+ The configuration file is divided in four sections. The user and
+ matita ones are self explicative and does not need user
+ intervention. Here we report a sample snippet for these two
+ sections. The remaining db and getter sections will be explained in
+ details later.

+
+ &appname; needs to store/fetch data and metadata. Data is essentially
+ composed of XML files, metadata is a set of tuples for a relational
+ model. Data and metadata can produced by the user or be already
+ available. Both kind of data/metadata can be local and/or remote.
+
+
+ The db section tells &appname; where to store and retrieve metadata,
+ while the getter section describes where XML files have to be
+ found. The following picture describes the suggested configuration.
+ Dashed arrows are determined by the configuration file.

+ How to configure the databases.
+
+
+ The getter
+
+ Consider the following snippet and the URI
+ cic:/matita/foo/bar.con. If &appname;
+ is asked to read that object it will resolve the object trough
+ the getter. Since the first two entries are equally specific
+ (longest match rule applies) first the path
+ file://$(matita.rt_base_dir)/xml/standard-library/foo/bar.con
+ and then file://$(user.home)/.matita/xml/matita/foo/bar.con
+ are inspected.

+
+ if the same URI has to be written, the former prefix is skipped
+ since it is marked as readonly (ro).
+ Objects resolved using the third prefix are readonly too, and are
+ retrieved using the network. There is no limit to the number of
+ prefixes the user can define. The distinction between prefixes marked
+ as readonly and legacy is that, legacy ones are really read only, while
+ the ones marked with ro are considered for
+ writing when &appname; is started in system mode (used to publish user
+ developments in the library space).
+
+ The db
+
+ The database subsystem has three fron ends: library, user and
+ legacy. The latter is the only optional one. Every query is done on
+ every frontend, making the duplicate free union of the results.
+ The user front end kepps metadata produced by the user, and is thus
+ heavily accessed in read/write mode, while the library and legacy
+ fron ends are read only. Every front end can be connected to
+ backend, the storage actually.
+ Consider the following snippet.
+
+
+ mysql://mowgli.cs.unibo.it matita helm none legacy
+ file://$(matita.rt_base_dir) metadata.db helm helm library
+ file://$(matita.basedir) user.db helm helm user
+
+]]>
+
+ Here the usr database is a file (thus locally accessed trough the
+ Sqlite library) placed in the user's home directory. The library one is
+ placed in the &appname; runtime directory. The legacy fron end is
+ connected to a remote &MYSQL; based storage. Every metadata key
+ takes a path to the storage, the name of the database, the user name,
+ a password (or none) and the name of the front
+ end to which it is attached.
