Descriptor definitions for calendar event are unclear

Original ticket from lloydleebarber edited to provide a summary and remove unnecessary details. 

Ed-Fi does not document the definitions of descriptors and therefore some of the semantics can be unclear. This seems to be the case with Calendar Event Type, where it was unclear how to map from Ed-Fi's default descriptors to agency defined values.

From the original ticket description (see ticket history for original):

We have a data analyst that is helping write the descriptor mappings between Infinite Campus and Ed-Fi.  I have provided a first pass for him to see how our values might be mapped to Ed-Fi descriptor values.  The issue isn’t what those Ed-Fi values are, but what do they mean.

Here is a mapping table of what I am talking about…he’s having trouble mapping some of them because he doesn’t know what Teacher Only Day means, for example.

See below

Ed-Fi Value	MNPS Value
1 - Emergency day
2 - Holiday	CH - Holiday - Christmas OH - Holiday - Other SH - Holiday - Spring Break
3 - Instructional day	Normal School Day OI - Discretionary - Instructional WN - Commissioner Waived School Day
4 - Make-up day	MA - Make-Up Saturday MD - Make-Up Extend School Day MH - Make-Up Previously Designated Holiday MS - Make-Up Extend Service Program MU - Make-Up Sunday
5 - Other	AE - Attendance End Date AS - Attendance Start Date CE - Calendar End Date CS - Calendar Start Date MI - Missed Instructional Day OO - Discretionary - Other OV - Discretionary - Teacher Vacation TV - Teacher Vacation
6 - Strike
7 - Student late arrival/early dismissal	AD - Abbreviated Day
8 - Teacher only day	IO - In Service Optional IS - In Service Day PT - Parent-Teacher Conference OA - Discretionary - Administrative OS - Discretionary - In Service SP - Stockpile - Professional Development
9 - Weather day	SI - Stockpile Inclement Weather

 

For example:  What does Student late arrival/early dismissal day mean in Ed-Fi data terms?

Note that Ed-Fi historically aligned/derived its values from the CEDS Calendar Event Type - https://ceds.ed.gov/CEDSElementDetails.aspx?TermId=11596
