Transcript and Presenter's Notes

Title: METeOR update


1
METeOR update
  • David Braddock
  • Nigel Mercer

2
Agenda for this presentation
  • System and website development update
  • Help text and guides
  • Content reengineering update
  • Outcomes and implications
  • Opportunity for comment and discussion

3
System and website development update
  • Solution selected
  • Progress to date
  • Timetable for software development

4
Solution selected
  • Synop (company), Sytadel (product)
  • Content management system customisation
  • Benefits of editing and version control within
    Registry
  • XML-based
  • Focus on portal and help

5
Progress to date
  • Synop commenced work in July
  • User functional requirements analysis completed
  • Use case analysis
  • Data architecture and website architecture
    documents produced

6
Progress to date
  • First release to AIHW October 1
  • 87 object classes loaded as test
  • Graphic design for web-site ongoing, including
    logo
  • Administrator and web-content developer training
    underway

7
Help text and guides
  • Important element of METeOR to make the site
    user-friendly and to support users in
    understanding metadata
  • Provide support for metadata developers
  • Status
  • Plan developed (AIHW)
  • Timetable December/January

8
Help text and guides
  • 3-level model
  • Metadata standards help
  • What is a standard, how developed etc.
  • METeOR help
  • About the site, how to find/create metadata
  • Contextual help
  • Fields, buttons etc.

9
Timetable for system development
  • Original version October 1
  • Prototyping, development and refinement October
    January
  • Create and load help December/January
  • Load final metadata January 2005
  • Testing and release February 2005
  • Publicly available March 2005

10
Content reengineering - status
  • 972 items from current Data Dictionaries and
    Knowledgebase
  • 603 reengineered
  • 369 not required e.g. superseded items

11
88
367
456
50 glossary items
Data element
527
14
Total 1821 metadata items (31 ratio)
369
12
Content reengineering further work
  • Related metadata items review each existing
    relationship e.g. x supersedes y
  • Some made redundant by METeOR structures
  • Identify and load new related data links

13
Content reengineering further work
  • Data Set Specifications (which include NMDSs)
  • Load DSS item
  • Link to Data elements
  • Populate new attributes e.g. obligation, number
    of occurrences, sequence, justification,
    verification rules

14
Content reengineering further work
  • Add Registration Status values for each new item
    e.g. Standard, Retired, Candidate
  • Check for new items added during project
  • Work with NDDSU to address items in the
    development cycle

15
Content-reengineering timetable
  • All items begun by end September 2004
  • Definition of
  • Object class groupings
  • Property groups
  • Review of all items
  • Completed by end of December 2004

16
Next development steps
  • Prototype development of system and website
  • First demonstrations for stakeholders
  • Finalise content reengineering

17
Outcomes
  • Once launched METeOR will deliver..

18
Outcomes
  • A registry is consistent with new version of
    ISO/IEC 11179 international standard
  • Metadata structures (object class, properties
    etc) that show great promise for future
    development and management of national metadata

19
Outcomes
  • Metadata reengineered consistently defined and
    stored across all sectors
  • Integrated items now stored only once
  • Ability for different Registration Authorities
    (sectors) to register items at different stages
    in the standardisation process

20
Outcomes
  • Website providing help and support for users
  • Simple or complex searching and browsing to
    locate metadata
  • Record interest in items with email alerts
  • User session Basket of items of interest
  • Ability to print or download (word or pdf)

21
Outcomes
  • Developers can create metadata on-line, with help
    to guide them
  • Groups of developers can collaborate and edit
  • Submit to AIHW (as Registrar) when ready
  • Defined process for metadata items to progress
    through the Registry

22
Outcomes
  • National data dictionaries with consistent format
  • Significantly reduced time to produce national
    dictionaries
  • Significantly improved functionality for the
    Registrar to maintain and manage the metadata
    contents
  • DSS structure more flexible and focussed on
    aspects of data collection

23
Outcomes
  • Glossary includes defined terms used in the
    Registry
  • Number of issues/ inconsistencies/ deficiencies
    apparent in existing metadata
  • Much more obvious in METeOR
  • Unresolved issues

24
Implications
  • Issues that will arise with the arrival of METeOR
    include

25
New definitional material
  • Need to develop some new definitional material.
  • For example, where object classes are identified
    but where inadequate definitions are provided.
  • Authoritative references have been used, and the
    sources quoted in most cases.

26
Detailed metadata names
  • Data element (DE) names reflect the Data Element
    Concept (DEC) and the Value Domain (VD) names.
  • The DEC name reflects the Object Class and
    Property name.
  • DE names will therefore be long, but meaningful
  • Exploring options for short synonymous names

27
Object class model
  • Object classes continue to be the most difficult
    area to communicate and for users to accept
  • User confusion with modelling
  • User confusion over sub-types
  • Potential for overlap with properties
  • Need to balance technical correctness with
    usability
  • Subjective everyone has a view about which
    object classes need to be created

28
Object class model
  • Object classes have only been identified where
    justified by existing metadata content
  • The information presented in the object class
    model does not replace that in the national
    information model (i.e. different model for
    different purpose)

29
Object class model
  • Object classes are primarily used in METeOR to
    help users navigate to the metadata that they
    need
  • This functionality replicates the now defunct use
    of information model entities as an organising
    framework for the national data dictionaries

knowledge etc.

31
Implications for work of HDSC
  • HDSC will need to review and provide comment on
    metadata created in the new structures
  • HDSC will need to implement the new business
    rules
  • AIHW can assist with training and support
  • Suggestions welcome on training requirements

32
Scope
  • Reengineering has highlighted distinction
    between
  • Guiding standards i.e. where we want the world to
    be or head towards
  • Application / implementation standards i.e. where
    the world is right now (agreed)
  • Is there tension between the two? Is this a
    problem? Do we need to distinguish?

33
Risks?
  • Risk minimisation plan developed
  • System development
  • Initial testing phase about to start on
    interface, response times, usability not yet
    tested

34
Impact on users
  • Managing change to new content and structures
  • Added complexity
  • Longer names
  • More components to a data element than previously
  • Acceptance of changes made during reengineering

35
Maintenance and sustainability
  • Ongoing maintenance of METeOR and its content
    will be critical
  • This will require resources
  • IP negotiations with developer to ensure
    commercial opportunities can be pursued
  • Any ideas to generate resources and ensure
    sustainability of METeOR?

36
Discussion
  • Questions?
  • Issues?
  • Comments?
