Light curves in DAL

[esm]

Hi Petr,

Time series is now one of the projects of the IVOA Standing Committee on 
Science Priorities.

As you say, some effort has been done in the past in this field but 
quite scattered. The idea is to have a number of use cases prepared for 
Sao Paulo (you can find them at 
http://wiki.ivoa.net/twiki/bin/view/IVOA/CSPTimeSeries), cases that will 
be assessed against the current IVOA architecture by the TCG with the 
aim of giving solutions to problems like how to find time series 
services in the registries, how to make queries to them, how to describe 
the information,... We expect a significant advance in this field during 
and after the Interop.

Best regards,

Enrique.
