Plasma Node demonstrators

Plasma Node demonstrators

• 1/Registry
• Set of XML descriptors of planetary plasma data
  (MAPSKP, VEX, MEX)
• Compliant with the SPASE data model 1.2.0
• eXist database (native XML, parameter level)
• Search engine ( measurement type, region)
• Goals demonstration and experimentation
  (standard versus user requirements, SPASE
  extensions, )
• 2/Science
• Based on AMDA
• Use remote data (MAPSKP, VEX-MAG, HST) and local
  data
• High level tools and functionalities
• Goals demonstration and experimentation

AMDA Automated Multi-Dataset Analysis
(http//cdpp-amda.cesr.fr)

• Multi-spacecraft and multi-instrument data
• Visualisation
• User defined parameter computation
• Standard model computation
• Data and computed parameter extraction
• Event list production and management
• Automated and semi-automated (visual) search on
  the content of the data
• Access to external databases (now CDAWeb, MAPSKP
  , next SKR, VEX-MAG, HST images, MEDOC solar
  data, )

Mapskp Registry Search Engine

• Available _at_
• http//cdpp-spase.cesr.fr8800/exist-1.1.1/xquery
  /PlasmaNodeRegistry.xql
• Search criteria
• Time span
• Measurement type
• Observed region
• Resource type ( numerical data , display data or
  catalog)
• Response
• Spase Xml descriptor
• Possibility to use XSL style sheet for better
  presentation

Plasma Node Registry Next step

• Implement an OAI interface (to be harvestable by
  other VOs)
• Add metadata (HST,VEX, )

Implement a Registry for each node ? Which data
model ? ? Tasks for FP7

Architecture of IDIS registries

• Inventory of resources to what level ?
• Need at least  measurement type  to implement a
  use case
• For this level of metadata, it is mandatory to
  use a data model
• Current status not sufficient for FP6 ?
• Final goal up to the  parameter  level
• For the current inventory
• it is not necessary to have a distributed
  architecture ( one search engine registry on
  every node)
• It is not necessary to use the SPASE model to
  describe high level resources ( person,
  repository,) (see IVOA VOResource )
• To implement harvestable registries, it is
  necessary to use a data model to describe
  resources ? unreachable in the FP6 context.
• For FP7 we have planned to establish at least one
  model and dictionnary for EuroPlaNet
• Study the existing models (IPDA, IVOA,SPASE) to
  know whether they fit the requirements of IDIS
• One data model for IDIS, and a dictionnary for
  each node ? Several models?
• These questions requier a full analysis and
  experimental study.

10
What is necessary to implement a
searchable/publishing Registry?

• A data model SPASE,IVOA,
• A data dictionary
• Tools to edit XML descriptors
• Schemas to validate the descriptors
• A database to store the descriptors
• Science and use cases to implement the search
  interface
• Implement OAI interface to be harvestable

11
VSPO an example of VxO

• VSPO Virtual Space Physics Observatory
• http//vspo.gsfc.nasa.gov/websearch/dispatcher
• Could be a model for the plasma node(at least) ?

12
VSPO metadata registry

• metadata registry based on the eXist XML database
• metadata registry accessed via
• VSPO
• database browser http//vspo.vs3o.aquilent.com/exi
  st/admin/admin.xql
• OAI-PMH
• VSPO's OAI-PMH Repository instance is based on
  the OAIcat software http//vspo.vs3o.aquilent.com
  /oaicat.
• to harvest the registry http//vspo.vs3o.aquile
