Hi Bricos and Vince


> Is there other good practice to manage, store and share metadatas?


There are some interesting tools available, I understand metadata research
and development comes from biology -because of the need to store and
describe info and create trees of relations, and so on-

Some useful info:

Some tools I think you can explore for your project are:

http://fedora-commons.org/ (this fedora is not that fedora)

And some more about meta data and open source:

will post more info in a while
