Simple Codebook Meeting
April 27, 2015

Present: Michelle Edwards, Dan Gillman, Oliver Hopt, Steve McEachern, Mary Vardigan

The group went back to the mapping between DDI Codebook and what is in DDI4. In terms of Access Conditions, there is an Access module in Discovery, where it is streamlined. It looks as if availability and use statements are not included; everything is structured string. We might look at SAML or another controlled vocabulary for access control like XACML (Extensible Access Control Markup Language). The issue is whether the outside source maintains previous versions, which we don't have control over.

In terms of Other Material, this was all found in DDI4 except for the Other Material table. This was part of DDI Codebook to mark up a table for presentation. In terms of VarDoc version, none of that was in DDI4. In DDI4 versioning is done at a low level, so this is taken care of at a level of the model that is not about particular content but about everything – Identifiable and Annotated Identifiable. There is an ID and a version. The question is that in Codebook the description is applied against Variable; in DDI4 identification applies broadly.

The group traced identification through the DDI4 model and looked at Collections and Members. Version Type in DDI Codebook does not seem to be covered, but no one is using this. Type seems no longer relevant and related to documents rather than to elements. People who understand this element from the old way of thinking have to know that the idea of a version is being expanded. We need to table this for now but are leaning toward deprecating this element.

Coding Instructions probably maps to Fieldwork and Methodology, which we don't have yet in DDI4.

Simple Codebook Meeting

May 11, 2015

Present: Dan Gillman, Oliver Hopt, Larry Hoyle, Steve McEachern, Mary Vardigan 

The group continued its review of the mapping between DDI Codebook and DDI 4 – https://docs.google.com/spreadsheets/d/1VDbVz2KRRSX_KEf0IfuE-QqMyTDupftCZfBdBM6VPT8/edit#gid=2125503646.

The group returned to the elements regarding availability and access. There is currently no archive information in DDI4 and this needs to be modeled, perhaps at the upcoming sprint. In terms of the use statement, some is not covered in the access object in Discovery in DDI4. This needs to be modeled also. SAML isn't useful for us because it is too high level. Both data and metadata may need something attached. We might look at this in the Datum discussion (not only columns but rows) and also attaching things to the metadata to control access. This might be like annotations where it can be attached to anything – access could have a relationship to annotated identifiable. Then any object could have an access control. From access description to object could be another solution.
