Taking the above, in conjunction with the recent message from PAP, the implication is the root DSA will be necessary until all the majority of first level DSAs running QUIPU have been modified to correctly handle subordinate references, and tested in some way (e.g., re-running the OIFP tests). This is a big first step, and we will probably find these DSAs are running 1993 protocol systems before this happens. I think we need to look at something more practical in the interim. Effectively, the only thing the root DSA does for the current QUIPU DSAs is distribute the top level EDB file. Alternative mechanisms can be found to do this, e.g., FTP on demand, or some simple push on change mechanims. The exisiting QUIPU DSAs could then be configured (incorrectly) to say they hold this EDB as MASTER, and the project continue perfrectly happy without the root DSA. This would acheive the goal to removing the root DSA, without imposing some of the other requirements (requirements that are needed in the longer term). This would also help the existing QUIPU DSAs to migrate, as this pseduo root EDB, could then have correct knowldege references to the 1993 systems. Colin
