Discussion items

Topic	Who	Notes
VESPA + IMPEx	Baptiste Cecconi	IMPEx (Integrated Medium for Planetary Exploration) http://impex-fp7.oeaw.ac.at/ Plasma and magnetic environment for planets Selection, download, visualization and analysis Compare simulation with observation (in reverse way) Tools AMDA, 3Dview, CLWeb, IMPEx Portal Features: extendable standards as generic as possible web based Data Model for IMPEx data model for plasma simulations based on SPASE (data model for observational plasma data) IMPEx-DM is based on SPASE 2.2.2. And IMPEx-DM is now included as an extension of SPASE on SPASE web site. Current versions: SPASE-2.2.9 and IMPEx-1.3. Main component: SimulationModel: code description [Instrument] SimulationRun: parameters of a SimulationModel run [observation mode] NumericalOutput: 1 per type of SimulationRun output product Granule: 1 per output element (file, URL…) within a NumericalOutput IMPEx Configuration IMPEx configuration: XML with provider descriptors. tree.xml (for data product); methods.xml (for webservices) IMPEx Protocol 28 methods. Core = 3 methods (implemented in 3Dview): getDataPointValue getDataPointValueSpacecraft getDataPointSpectra Uses SAMP IMPEx technical information: http://impex-fp7.oeaw.ac.at/documentation.html IMPEx Portal web ste: http://impex-portal.oeaw.ac.at/#/portal IMPEx API view: http://impex-portal.oeaw.ac.at/api-view Latest released SPASE/IMPEx schema: http://www.spase-group.org/data/schema/spase-sim-1_0_0.xsd
LatHyS@LATMOS	Ronan Modolo	The tree.xml explorer developed at LATMOS by Sébastien Hess is available for download: http://impex.latmos.ipsl.fr/LatHyS_webservice_and_tree.zip It will be reused by ObsParis team, and could be proposed as a test framework for tree.xml files.
CCMC@CDPP	Vincent Génot	The CCMC is now considering using IMPEx (after years of discussions). A few simulation runs from CCMC are available in AMDA and 3Dview (local IMPEx tree, see below). IMPEx tree : http://apus.irap.omp.eu/AMDA-IMPEX/public/trees/Tree_CCMC_chablon5.xml
TRANSPLANET@IRAP	Vincent Génot	IMPEx schema (draft) : http://transplanet.irap.omp.eu/schema/spase-sim-1_0_1.xsd IMPEx tree : http://transplanet.irap.omp.eu/impex.xml Updated schema to be used for this workshop: spase-sim-1_0_2.xsd
MPI-AMRVAC@LESIA	Léa Griton	Developed in Belgium a long time ago for MHD adapted for Mercury case Preparation for BepiColombo/MMO theoretical studies for propagation of waves around mercury adapted for fast rotators no codes really available for this, for instance in the case of Uranus 3D spherical grid, adaptive meshing (could be automatic where steep gradient) First draft example tree for MPI-AMRVAC: tree_LESIA_Filippo.xml
MDISC@UCL	Vincent Génot, Patrick Guio	Magnetodisc model, with solar wind input. Polar coordinates prototyping in 3Dview: Initial file are in netCDF display into 3Dview (small routine inside 3Dview written by Laurent Beigbeder) In 3Dview IMPEx/2Dcuts are expected to be provided in VOTable IMPEx tree : http://astroweb.projects.phys.ucl.ac.uk/models/mdisc/impex/mdisc.xml First test to display MDISC data into 3Dview from IMPEx tree was successful. local IMPEx configuration in 3Dview: Selection of IMPEx product in 3Dview: Displaying selected product in scene: Update on DaCHS server at UCL: There was still problems with the access and web redirections. Server was upgraded to latest beta version (change in `/etc/apt/sources.list`) GAVO configuration file (`/etc/gavo.rc`) was also updated with the following section [web] bindAddress: serverPort: 8000 serverURL: http://astroweb.projects.phys.ucl.ac.uk:8000 Note the the port number is present twice. This appears to be necessary for the system to work properly. The `mdisc/q.rd` resource descriptor was also updated to use the latest `epntap2.rd` mixin definition file, as fixed during the VESPA implementation workshop of Graz. The use of a `csvGrammar` was discussed but not yet implemented.
VOISE@UCL	Patrick Guio, Cyril Chauvin, Renaud Savalle	SAMP input: Some time was dedicated to try to setup a SAMP input connection for VOISE. Installation of SAMP library is done. Retrieval of input URL through SAMP is working. Help from Renaud Savalle and Cyril Chauvin was greatly appreciated. Issues with the Django / Apache server on UCL side prevented finalizing this task. This should not be too difficult, but that will be a follow up activity. Results: Currently the VOISE results are sent by email. Usually very big files (>10MB, and even several 100MB...), so the emails are not sent to the requester. We could try to plan to modify this result distribution scheme to provide a link to data to be downloaded within a predefined period of time. This requires updating the Django code. We have to decide if it's worth investing into this (mostly time from PADC to help Patrick Guio).
LESIA-Mag@PADC	Baptiste Cecconi, Renaud Savalle	This service provides magnetic field line passing from a location given in input and for selected magnetic field models at Jupiter. It was built by Sébastien Hess a few years ago. It is not completely working. Tree for the LESIA-Mag service: http://maser.obspm.fr/IMPExWS/tree_Mag.xml Test interface: http://maser.obspm.fr/IMPExWS/TestWS.php More info: http://maser.lesia.obspm.fr/outils-services/autres/article/lesia-mag.html?lang=en Current question: why do we have a tree.xml for a computing service ? Possible answer: the webservice is using the tree.xml content to check for allowed input values.
Other	Vincent Génot, Pierre Le Sidaner, Baptiste Cecconi	How to transform text ASCII tabular data into VOTable. There is a webservice at CDPP, but is making a lot of assumptions on the table content: http://apus.irap.omp.eu/AMDA-WS/php/rest/getVotableFromASCII.php?url=https://ccmc.gsfc.nasa.gov/RoR_WWW/VMR/3539/Cluster-1/GSE_extract.txt not configurable at all There is a script by Pierre Le Sidaner used and adapted in several services: to_vot_titan.py it requires a son configuration file (Pierre Le Sidaner?) There is an old REST service developed by Baptiste Cecconi (not working anymore, but could be revived) as a collaboration with the HDMC (Heliophysics Data Model Consortium), linked with SPASE. http://typhon.obspm.fr/hdmc/event-list/index.php
Next steps	Baptiste Cecconi, Vincent Génot, Léa Griton, Pierre Le Sidaner	Organize a next workshop (2 days) in late May or early June, in Paris: include UCL, CDPP, PADC and LESIA. During that workshop, propose a seminar to PADC and/or LESIA-modelling-and-simulation-group Invite Sébastien Hess to the next workshop Pierre Le Sidaner to finalize ASCII→VOTable script. Need GROUP and FIELDref for definition of Reference Frame in use in VOTable Pierre Le Sidaner, Cyril Chauvin: see if LatHyS tree.xml explorer can be reused and proposed on a standalone server for testing and visualizing IMPEx XML trees.
