1. Infer high-level semantic descriptions from
   combinations of low level features
2. Semantic queries - display performance data for
   high-porosity fuel cells
3. Multimedia Presentations of assimilated results
4. Hypothesis Formulation/Testing Interface
5. Save and Annotate SMILSVG Presentations

Specific Gaps

• Grid/Web security
• Grid/Web management and deployment
• Grid/Web service interfaces for scientists
• Quality of service
• Automated service matchmaking, composition,
  choreography
• Negotiation and contracting
• Reputation services
• Semantic indexing of all data/media types
• Realtime data streams interpretation and
  correlation
• Ontology development, management, harmonization
• Service failure handling
• Collaborative Tools for Access Grids
• Group visualization and computational steering
• Group ontology development
• Archival and indexing of AG sessions
• Hypothesis testing, decision support
• Long term preservation of research data
• Dynamic integration of heterogeneous people,
  data, services and instruments

PANIC Architecture
Client-side software modules which control the
invocation of preservation services
Step 2. Semi-automated Migration
Components communicate with each other using
platform-neutral standards OWL-S, WSDL and SOAP
Delivers and invokes the chosen preservation
service
Provides an interface to Software Version, Format
Version and Recommendations registries.
Provides an interface to match service request to
Web service registries.

Open Research Issues

• Security issues - Shibboleth
• Authenticated access to objects with a URI
• Requires manual reconfiguration of web server
• Need to restart server to invoke changes
• Requirements
• Not just about files
• computation, data storage, analysis, simulation,
  visualization, services, instruments, bandwidth
• Fine grained access constraints
• regions of images, segments of audio/video,
  columns of databases, functionality
• Annotations and Metadata
• Dynamically changing policies short term

45
Unresolved Issues ctd.

• Need to combine policies in real-time
• Scheduling of multi-user, multi-site policies
• Handling inconsistent, incompatible policies
• eduPerson limitations
• Working with industry, government, communities
• Indigenous gender, tribal affiliation, status
• Ontologies for relating different LDAP schemas
• Interoperability
• X.509 attribute certificates, SAML assertions,
  LDAP
• VOMS, SAZ, PERMIS, CAS, Kerberos
• XrML, XACML
• WSRF, WS-Security, WS-Policy
• Need to support and combine different policy and
  attribute formats/languages

46
Unresolved Research Issues

• Add semantics to WSRF
• Replace vic/vat
• Improve access grid support, usability
• Efficient access Grid session capture, indexing,
  archival

47
Conclusions

• Still a large number of unresolved research
  issues
• Need to prioritize relevant research topics
• Feed and test outcomes in global middleware
  infrastructure
