Hi,
While working on the feeds parcel, I became aware of a technique that
some OSAF employees know as a "Morgen trick", which is used in
osaf/sharing. In this technique, a calender collection is used as a
logger that monitors repository synchronization. The benefit of this
approach is that Chandler can be used as a high quality browser to study
the logged data (as the log is really a calender). I think that this
idea has not been utilized to its full potential and deserves to be
discussed in this forum. It seems that this design could be used in many
places, for example in feeds. But why settle for having such a calender
collection for each parcel separately as we could have one global
calender collection, hereafter referred as log calender, for this
purpose that can be used everywhere in Chandler. To make this even
better we should be able to make queries to the log calender, which I
have understood is supported by the repository. I use SQL to illustrate
the idea whereas Chandler repository specific implementation would of
course be needed to make it work:
SELECT * FROM logcalender WHERE reporter = 'feedsparcel' AND timestamp
BETWEEN ... and show this as a calender
Open questions:
* We do not want to bloat repository with unnecessary large amounts of
data so a consideration is needed to choose what to put in.
* The proposed log calender cannot, nor should it, replace the loggers
that are currently in place. Again consideration is needed to choose
what to put in as there is no point in storing too much information in
two or more locations.
* Is such a calender logger technically feasible?
* Are there others who would like to use such a service given that it
were available?
* etc...
My original idea is that the log calender would contain information that
is useful for the end users but not beyond that, i.e. that are aimed for
developers for bug tracking purposes (of course it could contain those
as well). This is just an idea and far from being ready for
implementation so feel free to comment and suggest improvements.
Cheers,
Markku
