ODM, CDISC's Operational Data Model, version 1.x will be 17 years old in October, making it a mature standard. ODM has come of age, and it's time for ODM to take on a bit more responsibility around here. Toward this end, a new XML Technologies development team has recently started work on ODMv2, a substantially updated version of ODM that breaks backwards compatibility with version 1.3.x to add a number of significant new features. This post highlights some areas of new development for ODMv2. As ODMv2 is still in the early stages of development, the scope of the project and specific features are subject to change.

Dr. Hans-Georg Eichler, Senior Medical Officer, EMA, provided the closing plenary keynote speech entitled “Data standardization: (how) important for tomorrow's knowledge generation?” The presentation discussed the efficiency of knowledge generation in medical research and the need for augmenting knowledge generated by randomized clinical trials (RCTs) with other sources of knowledge generation. RCTs are geared to provide safety and efficacy assessments, but must be augmented with data on effectiveness of medical products. Data on effectiveness can be harvested from an increasing number of non-traditional sources, such as patient-level data sharing, sharing of comparator data obtained from RCTs, observational data, mixed treatment comparisons.

We load the CDISC Controlled Terminology (CT) published by the NCI Enterprise Vocabulary Services (EVS) into the SHARE metadata repository (MDR). When we're through catching up with our backlog we'll have more CT in SHARE than any other type of metadata, and we'll publish the quarterly CT content to the SHARE Exports page on the CDISC web site. One of the main differences in how we load the CT is that we load only the incremental changes. That is, we load the differences by generating diff files that contain only the changes between the packages published in the current quarter and those published in the previous quarter. The diff files are available for download, or they can be generated using the NCI's Diff program. This program is a Java application, and it is simple to set up on most machines.

If you're wondering where the XML standards like Define-XML went on the CDISC website, they've moved. They're now located under Standards/Transport. If you go to the transport page you can select from a fairly extensive menu of transport standards. There are a few transport options located elsewhere, such as Lab and the Analysis Results Metadata Define-XML extension. Read the post from Sam Hume, Head of Data Exchange Technologies, CDISC
Keeping your repository up to date with the latest CDISC Controlled Terminology (CT) packages represents a challenge to many organizations. The SHARE API make it easier to retrieve the CT packages and initiate the process of updating your repository. In this post I'll walk through the process of finding and retrieving the CT from SHARE using the API.

Having completed the SHARE API v1.0 pilot in 2016, CDISC recently announced the SHARE API Early Adopter Program for those interested in beginning to use the API right away. SHARE API access provides a RESTful web services interface to SHARE for retrieving new CDISC standards and terminology.
