Dublin Core Educational Work

• DC-Ed Charter
• The DCMI Education Community is a forum for
  individuals and organizations involved in
  implementing Dublin Core and other learning
  resource metadata in the education domain. The
  objective of the Community is to promote
  interoperability within the domain through the
  use of standard metadata and consensus good
  practices.

Dublin Core Educational Work

• DC-Ed Application Profile
• Aim to provide a modular AP to support
  interoperable description of educational aspects
  of resources
• Scope educationally significant properties
  available in Dublin Core any other educational
  properties, e.g. elements from the LOM
• Out-of-scope will not define or give guidelines
  for usage of non-educational properties, or
  non-educational usage of properties
• Modular this will enable people to plug in the
  AP with other APs they are using, e.g. the
  Libraries AP, the Scholarly Works AP, a modular
  accessibility AP, or a local AP

Dublin Core Application Profiles

• The DCMI Architecture Forum developed
• Dublin Core Abstract Model
• Singapore Framework for Dublin Core Application
  Profiles
• The Singapore Framework requires
• Functional requirements (mandatory)
• Domain model (mandatory)
• Description Set Profile (DSP) (mandatory)
• Usage guidelines (optional)
• Encoding syntax guidelines (optional)

Singapore Framework

Singapore Framework

• The Singapore Framework for Dublin Core
  Application Profiles

describe the functions that the application
profile is designed to support, as well as
functions that are out of scope. form the
basis of evaluating the application profile for
internal consistency and for giving guidance on
the appropriateness of the application profile
for a given use.

Dublin Core Educational Work

• DC-Ed Application Profile Task Group
• Functional requirements
• We have the following general requirements
• Support for Resource Discovery
• Support for Educational Use of Resources
• Extensibility
• Jurisdiction Neutrality
• Based on three general Use Cases
• (see handout or
• http//writer.zoho.com/public/brassada/Generic-Edu
  cational-Use-Cases )

11
Dublin Core Educational Work

• DC-Ed Application Profile Task Group
• Functional requirements
• What about more specific requirements?
• What educational attributes or properties do you
  want to describe?
• What are your real world interoperability needs?
• What do your users want to search for / by?
• What else?
• We want your scenarios /Use Cases in order to
  base functional requirements on real-world
  metadata needs

12
Usage Scenario

• A brief storyline outlining a sequence of events
• Written from an imaginary persons point of view
  - very specific
• Detailing the assumptions, situations, motives
  and expectations
• Plain English
• Not requirements - but gets us familiar with
  goals and provides useful starting point for Use
  Cases.

Example scenario

• A lecturer gets approval to deliver a new
  post-graduate course in Knowledge Management
  Principles. Resources for the course need to be
  identified, selected, gathered, and organised.
  Public domain resources may be copied to a
  repository at the institution for access by
  course participants only. The lecturer also
  conducts an environmental scan to determine if
  there are any courses of this nature elsewhere
  from which to benchmark and to identify possible
  third party content.

Activity

• Look at example Usage Scenario (handout)
• Write your own Usage Scenario
• Think about What does my institution / do my
  users need from educational metadata?
• Pairs - briefly discuss possible scenarios
• Then write a scenario each
• 15 minutes

Use case

• Is a collection of scenarios, expressing all
  possible behaviours as actor tries to achieve
  goal
• This includes the responses of any systems to the
  users actions...
• When writing your scenario are there steps in the
  sequence that could lead to the actor taking
  different path?
• Are there multiple methods to access a system?
• If a step in the sequence fails, is there an
  alternate action that could be taken?
• These alternate steps can be written up as
  separate scenarios. It is the combination of the
  different possibilities to achieving a goal that
  form the Use Case

Use Case vocabulary/terms

• Actor Something with behaviour. It might be a
  computer system, person (teacher, student,
  instructional designer, etc...), organisation or
  combination of these.
• Primary Actor A stakeholder who requests that
  the system deliver a goal.
• Other actors Other stakeholders who will get
  something from the use case.
• Scenario A sequence of actions and interactions
  that occurs under certain conditions.
• Extensions Alternative steps / possible errors.

Pointers

• Breadth before depth
• When in doubt write less, at a more summary
  level, in a more narrative form, its the
  communication that matters
• Handle failures as well as successes
• Avoid the passive voice write ltactorgt does
  ltactiongt
• Get the goal level right keep the detail in the
  right place
• Avoid the user interface in Use Cases

Activity (now or later)

• Look at example Use Cases (handouts)
• Write your own Use Cases
• Use your usage scenario as a starting point or
  think of other scenarios
• 15 minutes
• Take away forms / access them via wiki and return
  to DC-Education
