• From meeting minutes:
  • Michael: Link the dataset to the project page? In the pipeline have a clickable link to the project page (make project name clickable).
  • Brett: Link to a dataset directly? Is that obvious to users? Click on dataset link -> log in -> redirected back to dataset.

Dataset Discussion - Capture data-integrity issues [Ken Koedinger, Team Meeting, 8/15/2009]

• As a stakeholder in the DataShop project, I want to capture and publicize the data-integrity issues discovered with data sets so that data is better documented (and so we've fulfilled a promise to our funders to better document data).
  
• As a user of DataShop, I want to discuss datasets and have that discussion attached to the dataset so that others can comment and better understand any data-integrity issues I've found.
  

Linking to internal pages. [Alida, 10/18/2007]

• It would be handy if a link can be saved to any dataset, sample, page in the DataShop.
• Currently, https://pslc-qa.andrew.cmu.edu/datashop/DatasetInfo?datasetId=793 works if you are already logged in.

Non-KC Modeling

Automatic Distillation

• As an educational data miner wishing to develop a machine learned model with PSLC data, I would like to be able to automatically distill data features (e.g. custom fields) commonly used in past educational data mining research for a new data set (see, for instance, Baker, Corbett, Roll, & Koedinger, 2008 in UMUAI)
• Could be implemented as a plug-in
