I got it working! Perhaps I've some more questions, but for now I couldcontinue my work.

Excellent! Good luck with your project.

Did someone create a SQL language wrapper around multi_index? I think this could be a very great feature. People that know SQL could really easy use it without learning too much other stuff.

There's currently a very active debate going on with respect to the merits of two libraries which offer a more SQL-friendly interface to handle multi-index data structures (none of them is actually SQL compatible, though.) Google for RML site:boost.org to get some links to the discussion. RML site is http://visula.org/relational/ while RTL stuff can be found at http://boost-consulting.com/vault/index.php? &direction=0&order=&directory=RTL

I thought about using a lightweight SQL lib (e.g. sqlite) before I found multi_index. But I don't save my data into a file, so multi_index fits perfect.

You can also save/load multi_index_containers contents to/from a file via Boost.Serialization. Check http://boost.org/libs/multi_index/doc/advanced_topics.html#serializatio n Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
