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):
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).
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.
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).
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.
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.
