EIEvent Schedules

All,

I've been working on trying to craft a solution for our use of ws-calendar to get us the maximum benefit of schema validation. What I have come up with so far is in the enclosed schema files that represents my proposal for how to represent an EIEvent schedule that uses and is compatiible with WS-alendar. Note that I have generated some sample XML with the enclosed schema and if you take the XML file and perform a little namespace jujitsu on it, it will validate directly against WS-calendar.

Note that I put the new types in one file (EIEventIntervalType.xsd) and the extended elements in their own file (EIEventIntervals.xsd). By doing this I am able to create another file that contains the same elements, but has no extensions to ws-calendar (see EIEventIntervals-x.xsd) and use that to test that whatever I am doing is still compatible with ws-calendar. This is purely a validation exercise and in essence I create an XML example with my custom extensions in EIEventInterval.xsd and then modify that XML to change its namespace and point to the EIEventInterval-x.xsd instead. Since EIEventInterval-x.xsd contains no custom extensions and is based purely on ws-alendar that allows me to verify that any XML I generate with my custom extensions in EIEventIntervalTypes.xsd are not only compatilbe with ws-calendar in principle, but will in fact validate agasint the ws-calendar schemas by only changing the namespaces in the XML file.

Toby - I don't know how this approach maps to some of the stuff they are doing with GML, but it might be similar.

Take a look at the enclosed jpeg which shows my schema extensions/restrcitons to ws-calendar for a EIEvent Schedule.

Assuming that people think this is a reasonalbe approach, my next step is to perform a similar exercise with the EIEventInfo schedules and link them to theoverall EIEvent scheudle.
