[TYPO3] [advice?] Finding the right extension

[Xavier Perseguers]

Hello,

I would like to know whether someone may give me a good advice for using 
the best-suitable extension to manage groups of persons.

My requirements are those:

- a person has a few attributes such as name, address and photograph 
(tt_address seems just fine)

- persons are part of one a more group (addressgroups seems just fine)

- groups are hierarchical:
    -- A
       ¦-- B
       `-- C
   if I choose to display the group "A", in fact, I would like to get 
*all* persons, both from A, B and C (this seems not to be allowed by 
addressgroups)

- Persons are not only part of a group, they have a function in that 
group, such as "President", "Manager" ,... (addressgroups seems not to 
be able to deal with this)
- In addition, may persons may have the same function (such as "Public 
Relationship") but with different responsabilities (for public group X, 
public group Y, ...)
- I would like to be able to order functions in a group to get the 
president at the top of the list, with a section <h#>President</h#> for 
instance.

- I would like to display group XY on a page, but for each person it 
would be really nice to get a link to a detailed view of the person's 
properties to get, for instance, all groups she is member of.

Do you know a name for such an extension?

wec_staffdirectory seems to do this but I tried many months ago and it 
seems that it did not support a person to be member of multiple groups, 
leading me to be forced to recreate the person for each group she is 
member of, that is not manageable.

If the answer is "do it yourself based on tt_address and addressbooks, 
then that's OK but I do not want to reinvent the wheel if an existing 
extension does it for me :-)

Thanks for any advice.
