The major impact of logical requests is the access to the information is non-hierarchical.

pylda is a translator between the logical requests and a storage container (fs, db, p2p, etc.). The logical requests consist of a combination of keyword and metadata elements (attribute). This combination follows the bool algebra. As a trivial example, requesting the picture file:///tmp/hollidays/newyork.jpg taken the 11/07/2007, the request could be : hollidays & newyork & date:11-07-2007.

The pylda philosophy consider that the data access have to be able via logical request and via the container traditional method.

The metadata are saved in standard metadata XML files or inside the file (if the file format supports it, exif for jpg, etc.).

For performance, there will have an indexation but this indexation is not necessary to let pylda works : the index can be regenerated.
