Jorge's point of view is very close to mine. Analysing Rolando's
arguments I found that there are two general methods 'how to name an
symbol'. Sometimes there is mixture of them.

1. Glue model
Combining existing symbol we create new ones.
server + map = server_map [1]

+ we know what is on the picture
+ easy to find by keywords
+ better as first step (warehouse)

2. Semantic model
server + map = wms [2]

+ we know meaning of symbol
+ easy to find by context
+ better for implementation (target well defined)

There are constrains related to programming environment and size of
mature projects. In this case "svn externals" can be better solution. So
the question is rather which model (glue or semantic) we select and what
further detailed convention will follow.

My opinion.
Semantic model is easier to implement and more unambiguous.
Tango naming model is not specific software related and this is big
advantage compared to Eclipse. Both are well documented.
