RVWG 2019-06-03 Meeting notes

• Unclear that an MVP/POC will be delivered, review suggested work group charter and submit edits to GAT for review along with use cases. 

Use Case Framework:

• Propose for the framework we deliver a rubric to know what are the right questions to answer when working through use cases. Specially when we have well defined use cases, but there are still unknowns in the data available. Anything we can provide to guide. 
  • suresh.cherrolu:  I would be honest, we do not have a specific vetting process per use case. Any insights is a learning experience for us.
  • Billy Buchanan (Deactivated) : Here is a framework for the construction of visualizations that we could use: https://homes.cs.washington.edu/~jheer/talks/Heer-EffectiveDataVisualization.pdf. It also has a fairly simple framework for evaluating the quality of visualizations and in the talk he goes into some detail about the perceptual qualities of different visual encodings. I gave a talk a few years ago about data visualization and discussed principals of visualization in it: https://github.com/wbuchanan/stataDataVizSDP2016 the file ending with .key is the better version of the slide deck (the animations were not as good in the powerpoint version).

MVP work: Group would like to come up with something that allows for implementations to easily consume data and use OTS tools, or use the core visualization provided in the MVP. Unclear about how the Analytics middle tier and other available tools.  

Rosh Dhanawade All options are on the table, self serve data, core visualizations but we need a guided way to pick which ones are the community's path forward. I think Edwire has done a lot of work in the mu

Billy Buchanan (Deactivated) : The one thing that I would wonder with the multidimensional cube approach is how it would also help end users dig further to get to individual student level data. This may have already been solved somewhere, and would probably be fairly efficient for rendering/retrieval for sure. If the rendering happens client side, it might be easier to send the raw data (e.g., D3.js).

If there is an API layer couldn't it potentially be handled via JavaScript?

Rosh Dhanawade : EdWire has done a lot of work on the multidimensional cube space 

suresh.cherrolu : OpenGL to query the API? if we standardize the Data Out?

Ed-Fi Dashboards: Before we discuss Phase III MVP work we must answer the question of what to do with current dashboards.

Rafael Loustaunau :  The ETL or the crunching of the data is a bit of the road block today for student GPS dbs an SQL analysis cube -to build reports from? Something agnostic that can be used for any visualization

Sub Group Scope & Milestones

• Itzel Torres will send out updated charter with subgroup milestones for Phase II and a new Phase III that will include an MVP of the future visualization.
• Itzel Torres will send out survey for subgroup signup and availability for additional working sessions.
