XML is de facto standard for data exchange. Is there any common XML based standard for exchange of events data and rules on actions? Does your book discuss or covers? In order to demonstrate event processing which event framework you have used or covered in your book? This might be an attraction to your book for any one who want to learn event processing patterns/techniques applying a particular kind of framework.
Hi Tariq. There is not an accepted standard yet about how event meta-data is expressed; some of the current implementations indeed use XML representation of events, some also keep the rule representation in XML files. I believe that standards in this area will emerge (it should be more feasible now, since recently the market has moved from start-up dominance to bigger vendor dominance and they are more standard-aware), and standards will indeed be based on XML. In the book we explain the various formats that exist today in commercial products to represent the meta-data and programming artifacts.
