to import an idea

hello,

I need help to use a data table (mysql) in YACS.
1) who must preserve his initial structure (several thousands of recordings)
2) who uses the rights of the users of YACS.
3) and allows to add to modify. recordings

if I use a OVERLAY in a section it is necessary to create the articles ...... for each recording
if I use an importation CSV in an article not possible (too much recordings…)not modifiable easy, export ?
if I use an importation of a table difficult to joint the  YACS fields
and those of the table… put aside the title ( bug with the delimitors….)

to summerize:
I have an old book of cooking, which comprises all my recipes,
I am attached to his struture…;
I would like in a YaCS-RECETTES section,
to post, each article being a recipe (a recording of the table) and to be able to add, modify the recipes with the same structure.

a simple idea;

Thank you
