DataObjects for ldap

Hi! I would like to port the curent DataObjects to an ldap backend (ex. DB_DataObjects_ldap), as it has been done with DB_ldap. But I'm not yet sure how to do this: a) Should I keep the same API as in the SQL DateObjects for compatibility reasons. b) Change the API to a directory db based one, sure it would look similar. c) like b) but with somme alias methodes like those in the current DataObjects which refers to the ldap specific ones. d) all of the above is waste and you have a better solution ;-) I personally prefer variant b) because in ldap you don't have rows, tables and furthermore the data manipulation operators have diffrent names (not select, insert etc.). what are you thinking? regards Chrigu
