So, RCMap is the topic of this blog. The best way to give you preview is to export the relevant components as web pages. It is about the low-density lipoprotein lab test, or LDL. I could not get tooltips to show. Please take a mental note that the tool does show extra metadata as tooltips when I hover on the bubbles, especially on those Controlled Terminology. It looks like this:

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 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 themlaying a foundation for concept creations. 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.

Four, sustainability. Granted, it is more of an issue on process and resources (i.e., operationalizing the methodology) than the methodology per se. It is nonetheless a growing challenge with the an increasing rate of new TAs commencing. The toolset for creating research concept needs to be easy to use, quick to learn, and without a heavy baggage of inherent spreadsheet annoyances.
