Second part of the presentation in "WHY metadata for MY resources" workshop in TELSS 2010!

1. Metadata quality criteria
WHY metadata for MY resources? Palavitsinis N., Ebner H., Manouselis N.

2. WHY assess quality?
• Bad metadata  “Invisible” resources
• Bad metadata  Less “cool” things to do with
metadata (explain)
• Bad metadata  Mess…

4. Metadata Quality Review
• In Organic.Edunet, mainly based on Bruce &
Hillman’s framework we’ve chosen some
criteria to assess metadata quality
• Produced a grid to review metadata records
– Using 5 point scales
– Using Yes/No questions
– Using free text field for comments

6. Selected Criteria (1/2)
• Completeness
– Number of elements provided by the annotator,
compared to the total number of elements in AP
• Appropriateness
– Are the metadata values provided appropriate for
the targeted use?

7. Selected Criteria (2/2)
• Accuracy
– Do the values correspond to what is annotated?
– Do they reflect the actual resource?
• Consistency
– Are the values provided consistent with the
standard or the AP used?

& interface design

9. Setting up
• Divide <total number of participants> with 3
• Create X groups of three
• Each group must have only one laptop open
• Roles
– One person to handle the laptop
– One person to keep notes (will be collected)
– One person to report back to the plenary

10. 1st Step
• Which two metadata elements would NOT be
useful for describing context specific resources?
• Report back by identifying:
– The context – field of interest (as a group)
– One element
– WHY this is not useful

Time in groups: 5’
Reporting back: 1’ per group

Hi! I am Bruce & Hillman’s
“Repository Genie” &
I am here to grant you 3 wishes!
I can make your Learning Object
Repository score 100% in only
3 of the criteria presented!
The rest I will leave on the
annotators hands…
Choose wisely!!!

13. • Visit: http://whymetadata.jimdo.com
– Under JTEL2010 / Workshop / Workshop resources
• Read the criteria and what they actually mean
• Use the questionnaire to “wish” for 3 of them
– Reveal one wish in the end!

2nd Step
Time on your own: 5 mins
Reporting back: 5 seconds per person!

14. 3rd Step
• Imagine you have a big amount of resources.
How would you like to manage them?
– Traditional folder structure (Confolio)
– Tag-based folders (Google Docs, Flickr)
– Search-based folders (Thunderbird)

Time in groups: 5’
Reporting back: plenary & individually (on paper)

15. Questions to consider
• Is metadata quality linked to context?
• Do metadata quality criteria apply to all cases?
• Can the interface design ensure “high-quality”
metadata?
