SDTM SAS-based format enforces 8 character limitation.

XML based CDISC standards (e.g., DataSet-XML) do not require such limitation.  

This project goal is to support exports of data that in legacy mode conform to the 8 character limitation and in enhanced mode allow for names to exceed 8 character limit (and still conform to other requirements (e.g., no spaces, no reserved special characters)).

Tasks:

•  Analyze CDISC CT and limit the scope of the project to a subset of CDISC CT terms
•  Understand current SHARE infrustructureSHARE infrastructure
•  Extend NCI EVS concept parameters with a concept property that supports enhanced mode data wrangling (export) 

The project works with CDISC Controlled Terminology.

Decisions made:
target NCI EVS concept property as where the knowledge will live,
experiment with how to integrate in SHARE
focus on subset of concepts (discussion about variable names vs. other concepts)
