[TO: IVOA Interop list, IAU Div-B Time Domain WG]
Dear IVOA and Time Domain Astronomy listers,
I'm pleased to announce a new data-service and open-source codebase
which may be of interest, 'voeventdb', an archive and query-tool for
working with the VOEvent format (i.e., reporting of astronomical
This codebase comes in two halves:
- voeventdb.server is a database-store and accompanying RESTful query
API for archiving and retrieving VOEvent packets.
- voeventdb.remote is an accompanying Python client-library for
end-users (i.e. astronomers).
- Ready-made Python client-library
- Spatial filtering
- Web of citations querying
- Summary statistics
- Extensive filters, applicable throughout
- Full XML storage
- Loading / dumping of XML packets in plain-old-tarballs
Full details can be found via
You can also test-drive the Python-client library with no local
installation using an IPython notebook hosted by http://mybinder.org/,
simply browse to
and click on the pink-and-grey 'launch-binder' button.
We are in the process of writing a short 'white-paper' note to announce
the service to the wider astronomical community via Arxiv. In the
meantime, we wanted to share the project with this community as the most
likely early-adopters. Note that this is the first public announcement,
so we would greatly appreciate any feedback, even if it's just to say
'it's slow' or 'I can't get it to work because X' (Furthermore, if
demand is high and performance is poor we could probably move the
hosting to a larger server, so don't be shy).
Kind regards and happy transient hunting,
Tim Staley (on behalf of the 4PiSky project (http://4pisky.org)).
