We have come a long way
  • From a boy and dog in late 1997 to
  • Global adoption of SCORM
  • Content interoperability
  • Stable feature set and platform
  • A solid model for reusability
  • Widespread industry adoption
  • A story of partnerships (DoD, OSTP)
  • IEEE, IMS, AICC, ARIADNE, many others
  • NATO, PfP, Canada, Australia, U.K., many others
  • Military Services, IRS, CDC, DoL, NGB, NSA, USPS,
    TSA, VA, NASA, TSWG, others
  • Industry Daimler Chrysler, IBM, Microsoft,
    Boeing, LG, Verizon, Delta Airlines, Oracle,
    Cisco, McDonalds, Home Depot, others...
  • International Plugfest February 2004
  • Over 320 participants
  • 210 organizations
  • 37 Countries
  • 77 organizations participated in Plug and Play
  • Demonstrating more than 120 products including
    authoring tools, content examples, and learning
    management systems.

The Next Big ADL Thing
  • Okay, so what good is interoperable, reusable
    learning content if you cant find it?
  • -- Paraphrasing Dr. Paul Mayberry over a year
    ago (my recollection)
  • We need a means to discover content in a
    contextually relevant way, identify it, determine
    its location, and get it when and where we need
    it.
  • We dont have the means to do this today.

YAA Yet Another Acronym
  • Content Object Repository
  • Discovery and Registration Architecture
  • CORDRA
  • CORDRA is
  • A formal model that can be used to design
    federations of repositories (the CORDRA reference
    model).
  • A collection of operational systems built from
    the CORDRA model, including
  • a prototype implementation of a repository
    federation and
  • an operational federation of federations used to
    combined different CORDRA federations.
  • The activities and projects surrounding the
    definition of the CORDRA model and creation of
    the operational systems.
  • The CORDRA activities are being coordinated by
    the Advanced Distributed Learning Initiative,
    (ADL) the Corporation for National Research
    Initiatives, (CNRI) and the Learning Systems
    Architecture Lab (LSAL).

ADL Registry CORDRA
  • Provides a means to make learning content
    visible and accessible DoD-wide
  • Provides a framework for discovery of learning
    content within DoD and over time outside of DoD
  • OUSD PR is providing this registry service to
    DoD through DTIC
  • The ADL Registry is being designed by ADL, CMU
    LSAL, and CNRI, and implemented by CNRI.
  • DTIC will take over operational management in
    FY06 CNRI will operate it by end of this
    calendar year

17
ADL Registry and Beyond
  • The ADL Registry initially will support learning
    content however, other digital assets pertain
  • Other relevant content, such as performance
    support, simulations, and gaming are expected to
    benefit from this infrastructure
  • ADL will continue to seek out the appropriate
    interface points among related but historically
    disconnected functions (administratively)
    connecting across stove pipes
  • ADL will focus on the architectural aspects of
    integrating with other environments such as the
    DoD Grid, S1000D (Performance Support), the
    simulation community, and others.
  • The ADL Registry Pilot is working now (early
    stage), and will be operational this year
    Summer target.
  • Our motto remains Working Code Trumps All
    Theories!

18
Policy DoD Instruction
  • DoDI 1322.hh is in final stages and expected to
    be signed by the end of September
  • High level policy is that
  • Learning content and LMSs acquired/developed for
    DoD shall be SCORM conformant
  • Learning content packages shall be placed in a
    locally managed repository that is accessible
  • Discovery metadata about the nature of the
    content packages shall be registered (and
    maintained) in the ADL Registry
  • Other types of content may be registered in the
    ADL-R for discovery and management purposes at
    the discretion of the DoD component

These terms will be further defined
19
Policy DoD Instruction (continued)
  • At this time, only DoD components and their
    support contractors may (and are required to)
    register content in the ADL Registry
  • This may be expanded government-wide at a later
    date
  • A process for vetting authorized repositories is
    in development
  • An overview of this process will be presented
    shortly
  • Feedback from this group is most welcome

20
Security/Access Issues
  • Actual access to content shall remain in the
    control of the local repository under its local
    policies
  • Only information (metadata) about the content
    shall be registered for discovery purposes
  • It is hoped that pan-DoD access policies,
    procedures and technical means will eventually
    evolve through joint activities such as this
    meeting
  • The long term goal is to make content
    discoverable, identifiable, resolvable and in
    due course, retrievable (accessible)
  • The latter will take time

21
Security/Access Issues (continued)
  • For now, only unclassified metadata about content
    objects may be registered in the ADL Registry
  • If the content is classified, but the metadata
    description about is not classified, than such
    content must be registered. There are metadata
    fields for the ADL-R that indicate the
    classification of the content referenced
  • The idea here is to enable search and discovery,
    but ensure authenticated access as appropriate
  • If the metadata is not classified, but the
    referenced content is classified, there is no
    requirement to make the content accessible
    without local approvals and clearances
  • It is hoped that in this case the registered
    metadata will indicate how an authorized entity
    may appropriately access the content.
  • If the ADL Registry metadata contains information
    that is itself classified, it is presently
    exempted from the DoD Instruction
  • This ought not be looked upon as a loop hole
  • OUSD/PR are planning to work with DTIC on secure
    systems to meet the needs of those who have
    special security issues
  • Guidance and policy with regard to secure systems
    is forthcoming

22
Security/Access Issues (continued)
  • Searchers/Users are unrestricted for now
  • Anyone may search ADL-R, but not anyone may
    access (thats a local decision)
  • Restricted search access will most likely be
    added based on local enterprise/component
    requirements (what we call a value added service)
  • We (ADL) need to get use cases and requirements
    from the DoD components to shape the additional
    services that need to be implement to support
    your mission
  • There are serious work-flow and configuration
    management problems that the ADL-R can be
    developed to support at fairly low costs
  • A great deal of thinking went into this
    architecture to support DoD Components, but we
    need use cases to build it out

23
A Short Bit on Packages
  • The DoDI requires that content be registered as
    packages. So what does that really mean?
  • Content packages are described in SCORM and may
    be tested for SCORM conformance using the SCORM
    conformance test suite
  • Packages are a way to wrap up all the things
    needed to deliver a chunk of content, regardless
    of what it is
  • Packages may contain a simple digital asset, a
    SCO, a short collection of SCOs, or a large
    group of SCOs (e.g., a course)
  • At present the DoDI is silent about what is
    packaged, or at what level of granularity, but
    the DoDI does require that content be in a
    package form, zipped, somewhere accessible,
    according to local accessibility policy
  • Other digital objects may be registered, such as
    performance support documents or raw assets, but
    that is outside of the current policy and is to
    be locally determined

24
ADL Repositories What are they?
  • An ADL Repository is a location where content
    developed or acquired by a DoD component resides
  • Such a repository is required by the DoD
    Instruction, but details of its implementation
    are not specified
  • The access rights to such a repository are to be
    determined by the DoD component
  • Such repositories may be operated by a support
    contractor under a DoD component-approved
    program, subject to approval by that component
  • We define a component as having a proponent who
    has the authority and responsibility for
    determining that a component repository is
    authorized and approved
  • We expect that the DoDI will be issued with a
    cover letter from our Under Secretary that will
    direct each DoD component to identify who the
    proponent shall be
  • It is assumed that this proponent will sanction
    and authorize who may, within each component, be
    official content repositories.
  • This is to be sure that there is some kind of
    accountability trail yet with the understanding
    that local policies must prevail
  • Once validated, repositories within their
    component shall operate against their own local
    policies and procedures, and will be granted
    access rights to the ADL Registry

25
Work Flow
  • So we think the process will be much as follows
  • DTIC will house and manage the registry, portal,
    and Handle System that comprise the ADL-R
  • When a DoD Component (or their designate, which
    may be a support contractor) wishes to stand up a
    content repository (in compliance with the DoDI),
    they will seek authorization from their
    designated proponent for their component
  • When such authorization is granted, DTIC will
    grant the approved repository manager access
    rights to the ADL Registry and will register the
    repository accordingly
  • Thereafter, it is assumed that there is a
    designated repository manager who shall be
    responsible for, and will delegate responsibility
    for, registering and updating metadata about
    content residing in the local repository or
    repositories
  • DTIC, as an official Handle System Naming
    Authority, will assign a unique prefix to each
    official DoD repository

26

    year
  • The current version is 1.3 1.4 will add access
    control
  • 1.5 will finish out the feature set and will
    include LDAP authentication for repository
    managers
  • There are 14 organizations participating in the
    ADL Registry Pilot
  • All have ties to DoD All are volunteers
  • All are testing and contributing to the registry
  • The include
  • All ADL CoLabs
  • Canadian DND
