In reply to Leonid Batkhan.

Traditionally, these Implementation guides have provided data set and variable metadata in PDF files and Excel spreadsheet. Recently this metadata has been made available through the so-called CDISC Library, To quote their website: "CDISC Library uses linked data and a REST API to deliver CDISC standards metadata to software applications that automate standards-based processes. CDISC Library provides access to new relationships between standards as well as a substantially increased number of versioned CDISC standards and controlled terminology packages."
With the CDISC Library users can now extract standard metadata in SAS using PROC HTTP, and then utilize this metadata to create data set templates, either as permanent SAS data sets or on the fly.
