May / June SHARE Update

During May and June the SHARE team has been busy on a number of fronts. In June we plan to begin beta testing the eSHARE site for machine-readable downloads of the CDISC standards.  The eSHARE site will be part of the new CDISC web site that will be launched in June. The SHARE team has also been actively designing new forms of standards content for SHARE, including Research Concepts and explicit Value Level Metadata representations. A white paper describing our initial solution for Research Concepts will be distributed for review in June. Also during June we plan to complete an initial proof-of-concept project towards a long-term Research Concept solution. Value Level Metadata (VLM) blog postings started in May and will continue through June. We plan to publish a white paper describing how VLM content will be represented in SHARE, and exported in Define-XML format, later in the summer.

The SHARE Metadata Curators continue their work with the foundational standards teams to load additional standards into SHARE, as well as to update previously loaded standards with new versions. Before the end of the year, we expect all the foundational standards teams to have started working in SHARE at some level. Loading the foundational standards is an important step in our transition to using SHARE as the CDISC standards development environment. It’s also a necessary step towards supporting Therapeutic Area standards development, and furthers the development of the CDISC end-to-end model.

Value Level Metadata, Vertically Structured Datasets, and Normalizaton

Image
As part of the work to implement Value Level Metadata in SHARE, as well as to author a Define-XML Implementation Guide article, this will be the first of a series of posts on the topic of Value Level Metadata. These posts target a more technical audience, however the Define-XML IG article will include less technical jargon. Future posts will cover additional Value Level Metadata topics and examples. Value Level Metadata (VLM) is metadata that constrains a variable definition based on the value of another variable(s). VLM was originally specified in Define-XML v1.0 as a mechanism for providing the additional metadata needed for software to more accurately interpret these constrained variables.  For example, VSORRES is a variable with structural metadata of  DataType=”Text” and Length=”200”. However, when VSTESTCD=”DIABP” that definition is constrained by VLM to use DataType=”integer” and Length="3". In this case, the value of DIABP in VSTESTCD has triggered the application o

ODMv2: Renovating the ODM Standard

  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. Among the more important new ODMv2 features will be a RESTful API that specifies standard methods of data and metadata exchange. The RESTful architecture uses specific URLs and the HTTP protocol to leverage pervasive, scalable web technologies to simplify data interchange. Lack of a common API for data exchange in clinical research has limited the available

What’s the difference between iSHARE and eSHARE?

Image
CDISC SHARE is a metadata repository (MDR) that supports the development, governance, publishing, and consumption of the CDISC standards in human and machine-readable formats. For more information about SHARE see the   CDISC Website . eSHARE and iSHARE are parts of the overall SHARE system. They represent two separate ways to access SHARE content, as shown in the diagram below. Interactive SHARE, or iSHARE , is the tool used by the CDISC standards development community for developing, governing, and publishing the standards. iSHARE is a cloud-based MDR configured for the CDISC standards that includes a number of standards management and development tools. Prior to accessing the tool, CDISC standards team members receive both on-line and interactive iSHARE training. Each standards development project works with the SHARE Metadata Curators to create and publish new CDISC standards. As new standards, and new versions of existing standards, are created iSHARE provid
