> Dear Collegues
> After receiving some feedback to the email reproduced below I
> propose the following
> agenda for the theory session in Kyoto, which is scheduled for
> wednesday morening.
>
> First we'll have some presentations, each about 15 minutes:
>
> 1. Dave De Young on activities regarding a data repository for
> theory simulations in the USA.
> 2. Enrique Solano: PGos3, a prototype for synthetic spectra and
> evolutionary model computation in the VO
>    (see http://ov.inaoep.mx/)
> 3. Laurie Shaw on data model and UCDs for theory (see his papers
> at the theory TWiki site
>    http://www.ivoa.net/twiki/bin/view/IVOA/IvoaTheory)   and/or
>    webservices for producing SZ maps and comparig them to observations.
> 4. Gerard Lemson: theory VO activities in Germany(see
> www.g-vo.org/mpasims, www.g-vo.org/planck,
>    www.g-vo.org/hydrosims, or
> http://gavows2.xray.mpe.mpg.de:8080/hydrosims in case the public site
>    is not up yet).
>    Upon request I will also present work done by the groups at
> JHU/Hungary on theory spectra
>
> These presentations about cover the subjects proposed in the
> email below, with some emphasis
> on theory spectra, which clearly is of interest for a number of people.
> I propose to have discussions about these subjects in the
> remainder of the session.
> In particular we should discuss:
>
> 1. Publishing theory datasets:, how to archive them, how to wrap
> them with web services them available.
> 2. Models for metadata describing these datasets.
>    Here we may pay special attention to theory spectra, as it is
> closest to the data model that
>    is developed furthest in the DM/DAL working groups, but offers
> different requirements.
>    It would be good if representatives of these working groups
> could attend this meeting.
> 3. Making theory services/application available online, both for
> analysing/visualising
>    these datasets and simulators for creating new ones. Here we
> should address interoperability,
>    how to tie different services together. And we should pay
> special attention to the interaction
>    between observational and theoretical services. I can discuss
> efforts that GAVO is involved in
>    with both theorists and observers around Munich and in various
> collaborations that have this
>    as their goal. It would be good if within the IVOA we could
> organize some similar projects.
>
> I hope that members of working groups can attend these discussions.
>
> Please send any comments to the mailing list.
>
> Thanks and see you in Kyoto

> > (http://www.g-vo.org, in particular http://www.g-vo.org/planck and
> > http://www.g-vo.org/mpasims) and is creating more that will be published
> > there soon, at least in a preliminary fashion. Please submit any links
> > to result to the TVO wiki page or send them to the mailing list.

> > The list of subjects I propose we discuss is:
> > 1. Availability of simulations online.
> > One of the goals of the theory group is to promote the publication of
> > simulation results according to standards developed in the IVOA working
> > groups. A prerequisite for this is that simulation results are actually
> > available online in some form. We need to have examples of this
> and look at
> > different ways in which simulations results are currently made available
> > online, which kinds of simulations are there, what services are provided
> > for accessing them. From this we can select a first category for which
> > we can look at ...
> >
> > 2. IVOA compatible publication of simulations.
> > We should choose a small set of existing examples which we want
> to further
> > develop and propose as use cases for the standards process. The further
> > development
> > should consist of work along the lines of the IVOA working groups. In
> > particular:
> > we want it to be possible to register data sets and services in an IVOA
> > registry,
> > we want to be able to describe simulations according to IVOA
> standard data
> > models,
> > we want to come up with standards for data exchange formats
> (VOTable?, UCD),
> > we
> > may want to see where the VO query language could be
> implemented and maybe
> > there
> > are some standard data access services we can define. Some
> proposals have
> > been
> > made, for example Laurie Shaw’s contributions on a simulation
> data model and
> > a
> > list of UCDs for simulation data. It would be good if these and other
> > proposals
> > can be discussed in the forum already before the actual meeting
> in Kyoto, so
> > that we may come up with some proposals we can make to the other working
> > groups.

> > 3. Theory/observational interface.
> > As has often been stated before, the holy grail of the theory
> work in the
> > IVOA
> > is to promote and facilitate the interaction between observers
> and theorists
> > by
> > defining and implementing services that make it easy for observers to
> > evaluate
> > and use the results of simulations. The standard example that is
> > consistently
> > mentioned is the "virtual telescope". A software component that can
> > "observe"
> > a simulation and produce mock images that can be directly
> compared to real
> > observations. GAVO is collaborating with a number of groups who
> have created
> > such tools which GAVO is publishing on its webpage. The planck
> simulator is
> > one, others are observations of hydro simulations of galaxy clusters and
> > mock
> > pencil beams through a large scale cosmological simulation. Based on the
> > various examples, it seems to me that this virtual telescope
> concept offers
> > a nice opportunity to come up with a modularized design
> specification that
> > allows explicit interoperability between components designed
> and implemented
> > by experts on their field. I am writing up a proposal on this
> that I will
> > submit to the mailing list in the coming week (I hope).
