Notes from Codebook Meeting 2016-04-26, 8am EDT
Attending Dan Gillman, Gillian Kerr, Larry Hoyle
We discussed the need to update column E in https://docs.google.com/spreadsheets/d/1VDbVz2KRRSX_KEf0IfuE-QqMyTDupftCZfBdBM6VPT8/edit#gid=1652443366  Larry will make a first pass at this.
Does DDI4 have the ability to describe a Reference period for a question e.g.  “over the last three months have you…?”  The ReferenceDate class http://lion.ddialliance.org/ddiobjects/referencedate has a typeOfDate property that should be able to do this.
We need a controlled vocabulary for the semantic of a ReferenceDate typeOfDate. Examples: the date range to which a question refers…. This will be a heavily used vocabulary. Should this be a choice in the standard? This is less flexible than an external vocabulary that can expand. The latter is preferable. The DDI Alliance controlled vocabulary group might address this issue.
What class will we use for the “study” in 4? GSIM has statistical activity.  We have derived data, experimental data, data collection from administrative sources. Scraped data from an administrative registry, mashed data from the web,  something like the consumer price index, qualitative data. TOFKAS – the object formerly known as study – TOFKAT the object formerly known as TOFKAS. Perhaps Thingamabob? Data Activity?  Study? ThatWhichWasCaptured? DataCollection? AcquisitionActivity? Whatever the name we need a class to represent the overall activity of creating/collecting the data.
