Over the past few weeks, @Vojtech_Huser and I have been using the Metadata and Annotations WG calls to discuss new standard concepts and concept hierarchies that can be used to represent our Metadata use cases in a standard fashion. These concepts (governed by the hierarchies) can then be utilized to represent Metadata facts (data quality, ETL/design, source provenance, or data content) and to represent Annotations from data or clinical experts. These representations then can be stored into a new Metadata schema of tables that can also maintain authorship and log activities.
Before our upcoming WG call on Friday, August 17, I’d like to ask those involved or interested in Metadata and Annotations to help provide feedback about the drafts of these efforts by adding comments into the documents linked below. The sooner we can reach a consensus, the sooner we can bring this to the CDM WG, and start developing a branch of WebAPI and Atlas that can utilize these new tables and conventions. Additionally, in order to support sites that don’t use Atlas, we will need to establish a library of standard queries and conventions to ensure that this new Metadata schema is used in consistent manner regardless of implementation.
In these Google Drawings files, you will find the concept hierarchies for Metadata and Annotation.
In this Google Sheets file, you will find worksheets detailing the new concepts we’re proposing, and a draft of the Metadata schema design.
Additionally, I will be attending @jon_duke’s Chart Review Question Interface WG this Wednesday to discuss these drafts and see where we need to make adjustments to support that effort.
