Inter-institutional Reporting

• Building Blocks
• CDEs
• Web services
• SSL for encryption
• Authentication using Kerberos/SAML
• Authorization, identity management using LDAP
• All of these pieces are used in Shibboleth
• http//shibboleth.internet2.edu/
• Grid services
• GridShib will provide security/identity
  management for the grid
• Demo

Parser, Data model and grid layer

• Grid layer
• Authentication
• Authorization/identity management
• Registration
• Advertising/Discovery
• Web services layer
• Data service
• Data model adaptor
• Validator service
• Syntactic interoperability announced through
  webservice
• Semantic validator available through the data
  model

5
Grid Methods

• Each institution maintains control of their data
• AnnounceService
• RegisterService
• Heartbeat (periodic announcement)
• DiscoverKnownServices

6
Service Data Methods

• Each institution maintains control of their data!
• Each service transaction is between a client and
  a provider
• GetCDElist (CDEs used at institution)
• GetCDEInfo (CDE info for items used at local
  institutions)
• GetData (For AEs - get current AEs the requester
  is allowed to see from the provider)
• Can be limited by protocol, institution, date
  range
• SendData (For AEs - submit the AE to the provider)

Background

• Advantages of transparent data sharing
• Speed of transfer
• Acknowledgement of receipt
• Compliance
• Statistical power (larger populations can be
  studied)

14
Background

• Example
• Sharing adverse event information
• This is only one of many examples of areas where
  sharing of data will have an immediate benefit
  for cancer patients
• Targeted groups
• Cancer center to cancer center
• Cancer center to cooperative group
• Cooperative group to cancer center
• Cancer center to NCI
• Cancer center to FDA

15
Building Blocks

• CDEs
• Web services
• SSL for encryption
• Authentication using Kerberos/SAML
• Authorization, identity management using LDAP
• All but CDEs are part of Shibboleth
• http//shibboleth.internet2.edu/

16
What we built

• Simple AE schema in Oracle
• Data dictionary in Oracle (we would like to use
  the CDEs for this!)
• Used the published CTC for AE definitions
• Used the existing NU AE entry module
• Web services servlet
• Web services browser
• WDSL file

Semantic Grid View

• Semantic services build on top of grid services
• Service interoperability
• Metadata identifies relationships among grid
  services. Which one is related to others. When to
  use one instead of the other
• Support advertisement, discovery, federated
  query, invocation and workflow

OGSA-DAI Architecture

• Previously heavily dependant upon OGSI
  implementation provided by GT3
• Currently has a three layer architecture
• Presentation layer - OGSI, WS-RF or
  WS-I-compliant services
• Business logic layer - the core OGSA-DAI
  functionality
• Data layer - the data resources (for example
  relational or XML databases) which can be exposed
  by OGSA-DAI services
