Bookings API and Public Bookings

There is no real documentation ATM. Some stuff can be found here: #594282: Documentation? Is this the correct module to do the job?

A short copy: At the moment Bookings API (6.x-1.0) is using an own, custom resource-type. Using nodes is not possible at the moment (I am writing on a new version which will use a node-based resource-type (6.x-3.0) but so far it is NOT usable). Thus it's not needed to add a custom node-type.
In the future Bookings API will add its own node-type for resources. In an even farer future, I will allow using your own custom node-type - but let me first get the easy stuff set up ;)
Steps to use Public Bookings:

1. Install Bookings API and Public Bookings
2. Go to admin/content/publicbookings/settings and activate the Booking form. Perhaps you like to check some other settings too? You can e.g. set the granulation of bookings, whether a confirmation of email-addresses is needed or whether an administrator needs to finalize (check) each booking.
3. Add Resources on admin/content/publicbookings/resource - there you can set whether a resource can be booked, if its available, etc
4. Use it ;) - Public Bookings has a public interface (/publicbookings) and an administrative interface ( /admin/content/publicbookings/ ). Have a look at both of them (resources can be added in a sub-menu of the administrative interface)

When somebody tries to book a resource (/publicbookings) , availability is checked prior to allowing this bookings.

You wont need Trigger or Rules - unless you want to combine Bookings API with one of those (e.g. send a mail to the admin upon recieving a new booking).

But feel free to ask any questions (please use the issue-queue of Bookings API or Publicbookings - I will get informed that way ;) ) and I'll try to answer them as fast as possible.

edit: I added some (very basic) documentation at http://groups.drupal.org/node/34868
