Re: [rules-users] Rules for generating calendar events

Hi Wolfgang Well, to be more specific the resources are taxi cars. Each taxi has their pre-defined shifts when they should be operating, then the drivers can sign up for which shifts they want to work. What I want to accomplish is to have a set of rules or formulas in a human readable syntax which at beginning of each month generate these shifts. The input to the rule/formula could e.g. be to iterate over the dates of the month something like this: Rule for shift: Every Monday 8-17 Input: Iterate over the dates of February 2012 Output: Shift (2012-02-06 8-17), Shift (2012-02-13 8-17), Shift (2012-02-20 8-17), Shift (2012-02-27 8-17) Would this be suitable to implement with drools or do you have a suggestion for a more appropriate tool?

The essential idea of a RBS is the selection of data ("facts") based on its attributes by conditions being evaluated over combinations of data items. Then, as a secondary activity, the RBS may be instructed to create additional facts. Generating facts out of Nothing is not the forte of a RBS; I don't see how you could write rules that generate "events" by deriving them out of - what? Perhaps you could provide more background? -W On 14 January 2012 02:47, sverker <sverker(a)abrahamsson.com&gt; wrote: Hi I have an application where I want to generate calendar events. Each event will have an attached resource and people will be able to book themselves to this event. The events are re-occuring in that they are on fixed time each day/weekday etc, like "every friday 07:00 -12:00 unless holiday" or something like that. The events shall be batch generated at beginning of each month and put into a database. I want the rules that generate the events to have some kind of DSL to be easily readable also for non-technishians. My question, would drools be a suitable tool for this task? I've been trying to find examples on the above but couldn't find any. /Sverker -- View this message in context: http://drools.46999.n3.nabble.com/Rules-for-generating-calendar-events-tp365 8179p3658179.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
