On-Line Knowledge Center (OKC). The top functionalities need in the OKC for DoD users are:

  • Provide a unified way to store and access knowledge for PET and DoD HPCMP users
  • Administrative and Research Portal for training (registration, assessment and curricula material), publications, announcements, CTA specific information, HPCC resources, PET Projects including informational material and rich suite of user generated input

The critical features of the OKC are:

  • Allow distributed knowledge update with efficient centralized approval
  • Provide robust security mechanisms and high-performance servers
  • Allow common look and feel with component model for all material
  • Information stored persistently in Oracle databases
  • Synergy with Grid Forum, HPCMO, community and commercial activities
  • Support e-mail or form (wizard)-based input and dynamic XML specified schema for all data and knowledge
  • Support multi-media, HTML, XML and CGI/Web service based data

The chart below describes OKC efforts by Component. The intent is for there to be a separate portal for each of the four Components that addresses the FAs managed by that Component. That portal could reside on the web space at the center, or it could all be centralized at ERDC. Each FAPOC or a designated set of on-site personnel will maintain the information content for the respective FAs. HPCMO will supply information on general outreach and the PET program. The operation of the full OKC will be accomplished by ERDC and by the MOS technologists resident there, assisted by technologists at the other three Component MSRCs. Technology development will be accomplished by and at Indiana University. Advice and consent from the PET management teams (both Government and contractor) and any outside advisory groups will also be considered.

There were no OKC project tasks in FY03.

The strategic roadmap for OKC is as follows:

FY04-07 areas of concentration for OKC include:

  • OKC-Tech: Ongoing deployment of key OKC Technologies:

 We expect all of these to be extensions and customizations of technology developed and supported for large-scale applications outside PET

 Current OKC built on Apache Jakarta technology linked to commercial database and message service systems

 Core technology including security and performance

 Component-based Distributed Authoring and Update

 Content Management with rich domain specific standards such as IMS/ADL for training

 Workflow for OKC knowledge updates including reporting and approval

 Multi-media support

 Search of structured (XML) and unstructured data

 Support for Web Service and older (CGI, Servlet) dynamic resources

  • OKC-Pages: Ongoing update of site content
  • OKC-FA: Customization of FA Specific Knowledge Centers (e.g. support RIB, ADL Training and each CTA …)
  • OKC-DSL: Support of and identification of other applications of the OKC approach such as online scientific libraries
  • OKC-Comp: Integration with PET computational portals and scientific data repositories
  • OKC-SW: “The Semantic Web for OKC” or support of data-mining, Intelligent Agents, and “digital brilliance” from enhanced meta-data
  • OKC-Outreach: Training on use of OKC and Requirement gathering

The OKC UAP includes:

  • Formal Advisory Panel:

 Bob Athow as Government PET lead for ERDC Component

 The CPOC and 1 PET Technologist for each component (8 members total)

 Representatives of CDLT and EOTC

 Other representatives to be added (HPCMO, DCs …)

  • Current Advice Structure

 Close working relation with ERDC

 Iterating prototypes with FAPOCs and PET technologists
