Sorting resources

In general we don't filter resources out based on any user properties, but rather sort the results.

Translations of a resource are all shown.

Calculating points for resources

Pieces

• 1 point for each time piece used in a resource
• 1 point if piece has a non-default title
• 1 point if piece has tags
• 1 point if piece has a description

Learning resources

• 1 point for each member that has this resource in his collections
• 10 points for each tip for use that has this resource

Activities

• 1 point for each member that has this resource in his collections
• 10 points for each tip for use that has this resource

Tools

• 1 point for each member that has this resource in his collections
• 10 points for each tip for use that has this resource

Members

• 1 point for each piece added
• 10 points for each learning resource, activity, and tool added
• 10 points for each tip for use written
• 1 point for each blog entry
• 1 point for every member who has contacted this person

Groups

• 1 point for each member
• 1 point for each blog entry
• 1 point for each assigned learning resource

If action is older than month, points are divided by every full month+1. (So, two month old edit is worth 1/3 point.)

Selecting featured resources

Select randomly 3 from:

• published resources within the section
• that have a cover image
• and that are in the top-N list in points
  • where N is 10% of the total amount of resources in the section (ie. with 100 resources, select from top-10, with 5000, select from top 500)
