Thoughts and Design Decisions

What information do we want captured?

  • Name (link to github, confluence page, what?)
  • Functionality
  • Actively maintained (satisfied by status)
  • License
    • Default no license file (None) to All Rights Reserved?
  • who made it/maintains it
  • example of in action
  • installation instructions or something. (trusting this to be attached to github page)
  • status
    • Live (maintained): green
      • This means someone can use it in their own Open edX instance
    • Live (abandoned): yellow
      • You can use it, but do so at your own right
    • In progress: blue
      • being worked on. You might want to message the contact.
    • Dead: red
      • I assume we want a dead one to mean "Total disaster" or something.
  • Notes column? Useful, but already looks busy
  • Whether it's merged?
  • Voting/rating (do people like it or use it?)


JCM:

as we have little space in terms of columns, I'd suggest we narrow it down to the columns that will help us accomplish 3 objectives:

1) give the name and description of the component

2) showcase the contributor (this is very important to get people to actually add items to the list)

3) key info to help users find what the need with filters, sorting, searching etc

for instance

to search:  description, tags

to filter: status, license, tags, provider, category??

to sort: rating  (I'm looking into alternatives with confluence pluggins or macros ex: https://marketplace.atlassian.com/plugins/com.adaptavist.confluence.rate
