Release of ADaM 2.1 and ADaMIG 1.0

CDISC is pleased to announce the posting of the Analysis Data Model Version 2.1 and the Analysis Data Model Implementation Guide Version 1.0.

About the Analysis Data Model, Version 2.1

The ADaM document explains the purpose of the Analysis Data Model.  It describes fundamental principles that apply to all analysis datasets, with the driving principle being that the design of analysis datasets and associated metadata facilitate explicit communication of the content of, input to, and purpose of submitted analysis datasets.  The document also describes ADaM metadata, the subject-level dataset ADSL, and a new multiple-record-per-subject data structure:  the ADaM Basic Data Structure (BDS).  The Analysis Data Model supports efficient generation, replication, and review of analysis results.

About the ADaM Implementation Guide, Version 1.0

The Analysis Data Model Implementation Guide (ADaMIG) is a new document that is intended to guide the organization, structure, and format of analysis datasets and related metadata.  It specifies ADaM standard dataset structures and variables, including naming conventions.  It also specifies standard solutions to implementation issues, illustrated with examples.  The ADaMIG must be used in close concert with the current version of the Analysis Data Model document.
