<snip> I'm a bit stuck on how to design an event system for our needs. The current offerings are overly complex for our needs and do not take kindly to some of the variations we need. I would like to discuss with a Drupal 7 expert who can advice on taxonomy design and implementation. Thank you in advance Roger

There are several on line event web applications. Why do you want to create one yourselves? Now I once created a system that allowed an administrator to manage contracted cooking instructors. These instruction sessions were events. Events with a venue, a schedule, various players who had to be contacted, supply ordering and fulfillment that needed to be done, verifying that the contract was actually being fulfilled, and paying the contracted instructors through an invoice system. All this was accomplished without using a Content Management System. What are you trying to do? Sometimes defining the problem is nine tenths of the solution. - George </snip>

Thanks George The key issue for us in using one of the event systems already available is that most of what they provide is overly complex, much is of no use or just clutter. I have explored 3 or 4 to date.

This Drupal 7 system is at this time for Australia only.

Our events needs are fairly simple, I'm well into the process on our test site.

We have about 20 slightly differing event Content Types, these include general meetings, member's meetings, Book Readings, Classes, Services, Itemised Discussions, each for public, for members only, for teams only and for specialised teams.

We have other specialised meeting types for public and members which do not fit into the above categories.

Then there are team member meetings anywhere across Australia called without notice.

My observations: All events have a venue, a location, a state, a convener, a title, a date. The date for some event types repeats weekly or monthly for 3, 6,or 12 months, infrequently 18 months. Other events have a single date or repeat for 2 days. Some events have the same convener for the full repetitive cycle, other events may have up to 3 conveners at each meeting and these may be different for each monthly meeting. Other may have 2 conveners who swap each month.

Some events have literature requirements where a book or document is a reading prerequisite.

I have the data entry form Title field set to automatically predefine prescribed titles which makes views far easier to work on (Thanks to Nancy).

I have taxonomy vocabularies for: Book references Venues Location State Event types Event titles Authors Contacts And several more.

There are 8 States, 70 Locations and 100 venues and over 2000 events per year across Australia.

Venue Terms are the local names of venues like "433 On Logan" or Melbourne Exhibition Centre" Location Terms are say Canberra, Newcastle, Tongala, Bentleigh, Moe. State Terms are QLD, VIC, SA, TAS - Australian states.

My question was to be more along the lines of, say with State, Venue, Location. A state can have more than one location A location can have more than 1 venue. A Venue has a Location and State.

I am currently providing Venue, Location, State Term References for each event content type. This is doubling up information as each table over the course of time will contain very similar information.

I have tried putting a Location and State field in each Venue term but find that these do not display and do not know how to get them to do so after an event data entry is displayed.

I have tried adding Location and Venue to the State Terms

I do not know which is the most appropriate way to provide the 3 lots of data from one Term Reference field in each event Content Type.

I'm thinking of just providing the Venue then the location and State are automatically linked. This way the coordinator has only to select the venue from the Term Reference field. Only the Venue has a link to address information and a map.

I have tried a number of ways but am more confused now.

I greatly appreciate any help I can get Thanks in advance Roger
