  1. Catering for different user’s profiles in HELIO TCD & The HELIO Consortium Vilnius, 11.04.11

  2. Introduction HELIO is designed to help scientists: finding, retrieving, and analyzing data regarding the sun, its related phenomena and their effects on: the Earth, and, the other planets of the Solar System. HELIO ???

  3. Technological Challenge Different User’s Profiles • Data and Metadata • from the various instruments are: • Dispersed • Non completely standardized • There is a complex feedback between data and metadata. HELIO • Codes and Computational facilities are: • Dispersed • Non completely standardized

  4. Different users HELIO Access Layer + HELIO API + Community Interaction Service Users that do not possess a Grid Certificate BUT are willing to login to the HELIO portal Users that do not possess a Grid Certificate AND are NOT willing to login to the HELIO portal Users that possess a Grid Certificate Prefer to use IDL code Prefer to use HELIO Portal Prefer to write workflows Security

  5. Different Resources Low Security High Security Authentication Authentication Authorization Simple User Profile Security

  6. HELIO Architecture (Abstract) HELIO Service Resources Access Layer HELIO API HELIO Service Resources HELIO Service Resources • Connects to services independently • Use them in a workflow • Use a GUI • IDL, Java • Decoupling layer • Hides unnecessary Information • Data & Metadata • Storage • Computation • Existing Code • Security • Web Service • Based

  7. The Access Layer and API Workflow Engine (Desktop) Workflow Engine (Server) Service I API HFE Standalone GUI

  8. The Community Interaction Service Community Interaction Service Authentication Back End HELIO Identity Token Access Layer & API Service

  9. The HELIO Identity Token 1/2

  10. The HELIO Identity Token 2/2 Proxy-based component (for high level of security) UID-based component (for low level of security) KM234454353GD User Profile (Based on the ClassAd language) [Service=HEC; Preference=...;]
