Requirements and limitations
• support for all major blogging platforms using open standards (RSS, Atom, trackback, pingback)
• no special plug-ins should be required on the student blogs
• the scope of EduFeedr is limited with aggregating and annotating the feeds from both teacher’s and students’ PLE’s and visualizing the process of knowledge building
• only teacher has an user account in EduFeedr, which allows her to modify the EduFeedr settings
• anyone has read access to aggregated course content

Locating the Comments Feed
• Comments feed location is not always specified in the web page
• Currently we support only Blogger and WordPress
• Possible solutions:
- Specifying the comments feed location for major blogging platforms
- Adding the comments feed manually
![Page 38: Aggregating Student Blogs with EduFeedr: Lessons Learned from the First Tryouts](https://reader033.fdocuments.in/reader033/viewer/2022051513/5479c70ab379593a2b8b487f/html5/thumbnails/38.jpg)
Linking Student Posts with the Assignments
• Methods
- Link to the assignment post in the course blog
- Assignment deadline
- Asking from the facilitator
• In the first course 10 posts from 91 contained the exact link
![Page 39: Aggregating Student Blogs with EduFeedr: Lessons Learned from the First Tryouts](https://reader033.fdocuments.in/reader033/viewer/2022051513/5479c70ab379593a2b8b487f/html5/thumbnails/39.jpg)
Linking Comments with the Participants
• URL in the comment metadata is used to link the comment with a participant
• Comment meta URL’s in the first course (100 comments):
- participants’ blog in the course (3)
- Blogger profile URL (57)
- URL in the WordPress user profile (18)
- OpenID URL (7)
- No URL (15)

Only Recent Items are Stored in the Syndication Feeds
• Blogger feeds contain 25 most recent items
• WordPress feeds contain 10 most recent items
