I recently studied the SHARE metadata display templates (MDT) attached to two Therapeutic Area User Guides (TAUG), Asthma and Diabetes. My first reacion, "Oh no, more spreadsheets." I wrote blogged here explaining how loading metadata from spreadsheet wasn't as easy as it seemed. Creating research concepts in spreadsheet format adds another new dimension of complexities. But, before we go deep into this blog topic, first please know I recognize MDTs in the aforementioned TAUGs are prototypes and acknowledge a great deal of effort was put in to creating them. Second, it helps to describe the methodology as I understood it: These templates use multiple data element concepts (DEC) to describe a group of related research concepts. Each DEC consists of BRIDG class and attribute, ISO 12090 data type, SDTM variable, and CDISC Controlled Terminology. A single research concept can be created by instantiating from an MDT, subtracting irrelevant DECs, and constraining with additional controlled terms.
