Hi Mariano,
Here is the description for a project related to Pier.
Cheers,

----------
Extensible parsing and persistency for Pier
Mentors: Tudor Girba, Lukas Renggli
Pier is an open-source content management system that aims at allowing
users to manage their content from the browser. It is based on a
highly object-oriented model dealing with multiple issues: multiple
types of structures that are meta-described, security management, user
management, or persistency. The preferred way to define content is
through an wiki-like syntax. Using this syntax, the user can specify
multiple types of links, can choose to embed entire structures, and it
can even access external services (like YouTube).
This project will tackle two important problems related to extending
Pier:
1. While the Pier model is extensible the parser of the Pier syntax
is not easily extensible. The first job will be to rewrite the Pier
parser to offer hooks for syntax extensions. A possible path towards
this implementation is the use of the PetitParser framework.
2. The main persistency mechanism in Pier is image-based. While the
Pier model is meta-described for most parts, there are still parts
that are accessed directly without the use of meta-descriptions. This
poses a problem for a generic persistency mechanism. The second part
of the project will focus on providing a mechanism for allowing each
structure to specify a persistency strategy.
Benefits for the student:
- learn about meta-modeling and parsing.
- learn Seaside and work on a platform that has a wide acceptance
already.
Benefits for the community:
- a better content management system
