Real Database File Type Problem

[JMC]

I am having a little problem adding the database file type, I am
planning on using a Real SQL Database ( Realbasic own database type )
but I am not sure on what should i put on :

1. Display name
2. Object name
3. MacType
4. MacCreator
5. Extensions ( I am guessing that one is .rsd )

I know this is a bit of a silly question but i cant find the answer
online and in the previous RB version the file type dialog box filled
that for me

Any help

Thanks

If your program will be available for others to use, the macType and
macCreator you should get from Apple by registering your software. If
you have not, you should join the Apple developers community
