I wanted to ask a question about server data. I am new to server programming, but I have to learn about the CardDav server (CardDav is developed by the WebDav).
I only know the CardDav server is used to hold the address book data, but what form of the data does the server actually hold (e.g. .CSV or .txt)? Can anyone help me? Thank you very much.
The file format used is vCard; the wikipedia entry contains a basic explanation of the file format:

For the gory details, take a look at RFC2426: https://www.rfc-editor.org/rfc/rfc2426
