Extracting metadata to enable simple repository deposit Dawn Wood & Janet Finlay Leeds Metropolitan University

First … What KEYWORDS would you use to for this image?

Self-Deposit

Workflows: Recorded Lecture Course/Module materials

Workflows: Create Podcast

Workflows: General LO creation

Observations of metadata creation When entering metadata for a learning object observations show that: ◦ Phrases rather than single words are used ◦ Repeated content is often used ◦ Very few keywords are entered if any ◦ The keywords used were either very specific or very generic, rarely a mixture of both This creates a problem for searchers of information and limits the possibility of the learning object being found within a repository

Assumptions Deposit of existing materials ◦ Just add metadata Documentation describes the learning object More keywords are better ◦ This is reliant on good search techniques Not starting from a blank slate is easier ◦ Generate a selection list ◦ Author still feels in control

Example Results for Podcasts For a Podcast on Accessibility produced by CETL ALiC One of the authors used the following key words and phrases: ◦ HCI ◦ Accessibility ◦ User centred design ◦ Disability Remember that different users will find different aspects of your interface difficult. For example users who are colour blind will not see colours as you intend and may not be able to distinguish between colours on the screen. You can test how your colours will look using an online simulator.
