Hi all,
I'm working a bit on the unsupported temporal module for ISO 19108
implementation ... actually is in a quite good state even if still remain
something to implement (
http://docs.codehaus.org/display/GEOTOOLS/GeoAPI+Temporal+Implementation),
anyway, as I said on previous emails, it can be promoted to supported state.
Actually I'm writing this email not only to ask you to promote the temporal
module but also to rise up several questions and issues I'm facing while
working on this stuff...
With the occasion of another review of the temporal module, it would be good
to improve the actual referencing TemporalCRS with the ISO 19108
implementations.
I volunteer for this job of course but I have some dubts that I would like
to share with you and hopefully start a thread in order to quickly find a
good solution or path to follow.
While taking a look at the GeoAPI interfaces I discovered that there are
some discrepances between the org.opengis.referencing.crs.TemporalCRS and
the org.opengis.temporal package ...
in particular:
1. there is no correlation
between org.opengis.temporal.TemporalCoordinateSystem
and org.opengis.referencing.cs.TimeCS and moreover on
the org.opengis.temporal.TemporalCoordinateSystem javadoc I can see a note
saying "TODO: Retrofit in TimeCS."
2. in the org.opengis.temporal package there is no concept of TemporalDatum
nor of TemporalCoordinateReferenceSystem
those two observations let me guess that there is the intention of unify
those two packages someway, most probably unifying the temporal.referencing
objects with the referencing ones.
Now ... this problem is a little bit blocking .... someone has some hint,
idea or knowledge about it?
Should I ask this to Martin Dressuassoux or Mehdi Sidhoum?
And also, seems to me that GeoAPI is quite incomplete on this matter, we
maybe have to redefine some interfaces and GeoTools implementations.
Thanks for your attention and help.
Regards,
Alessio.
