Howdy,
I don't have much time playing with qi4j these months, but I keep reading this
list with a lot of interest. EventSourcing feels important.
About the format to use, I personally tend to prefer json over xml for its
lightness but in practice xml is a good fit in a lot of case. So as David I
trust your judgement.
Ok, thanks. I actually started on a JSON serializer, but changed my mind
for two reasons. One is that the data will be incorporated in Atom
feeds, so mixing XML and JSON feels weird, and the second is that there
are better tools for working with XML structures, specifically XPath and
XSL.
A lot of uses I can see for EventSourcing would be about triggering
rules based on XPath queries (e.g. "for event on property Foo, when
value is set to X, increase counter in statistics report"). But, both
are possible, for sure.
