SHARE 2015 Q4 Technical Update
The SHARE API Pilot continues to make progress. A draft
specification is being reviewed and a test server is running the API as
currently specified. The pilot team will finalize the draft specification and
spend the rest of the year testing and developing interfaces to the API. The
SHARE team will also make use of the API to enhance tools in the SHARE
ecosystem by making it easier for them to consume SHARE metadata. The SHARE API
will be moved into production during Q2 of 2016.
A few last development details are being cleaned up for the
SHARE RDF export, and then we'll work to generate a test export for the
community to review. The initial exports will include SDTM, CDASH, and
Controlled Terminology. The RDF content will be posted to eSHARE, and will also
be available for consumption via the API once it has been moved into
production.
The Biomedical Concept (BC) development tools have seen a
number of upgrades this year. These tools are currently being used by the
Collaborative Curation Initiative (CCI) to develop the BCs for the Prostate
Cancer TA project. We're currently working to update the BC model within the
SHARE MDR. Some have expressed an interested in gaining early access to this
content via eSHARE and the API. Given BCs usefulness in supporting process
automation and the generation of study artifacts, software vendors are keenly
interested in the continued development of this content in 2016.
Over the course of 2015 eSHARE access has been expanded
beyond Platinum members to include Gold members and academic researchers. For
those interested in learning more about eSHARE, the webinar we delivered for
the Gold member rollout is a useful place to start https://www.youtube.com/watch?v=NCjnnaaS4H4&feature=youtu.be.
New content is continually being posted to eSHARE as it becomes available.
Earlier this year the first version of ADaM 2.1 was posted, and an updated
version that includes new input from the ADaM team is expected soon. New TAUG
content continues to be posted as it becomes available. In December we plan to
post some new catalogs and listings, to include the Domain Catalog. A BRIDG
alignment report generated as part of the BC development will be posted for
review. Finally, we plan to post an SDTM to CodeList spreadsheet that maps
Controlled Terminology CodeLists to SDTM variables by the end of the year.
A draft position statement was created by the SHARE team
with input from many stakeholders. Please add your comments to the wiki page: http://wiki.cdisc.org/display/SHARE/LOINC+Discussion%3A+3+Nov+2015+-+SHARE+Telecon.
Protocol standards were not available for loading into SHARE
during 2015, but we plan to begin loading protocol objectives and endpoints
into SHARE during 2016 Q1. Given all the
activity around the development of a protocol standard, the SHARE team plans to
work with the CDISC terminology team and the NCI EVS to create a protocol vocabulary
that can be loaded into SHARE. Before the end of the year, a proof-of-concept
using elements of protocol in an end-to-end standards representation is
planned.
Structured validation rules are currently under development
by the SDS and ADaM teams. SHARE will use the wiki templates to develop rules
in support of the TA standards using this format until a rule formalism is
agreed upon. Once the formalism has been selected, the SHARE MDR model will be
updated and rules in this format will be loaded. The new rule format will be
piloted in 2016.
A wiki-based example repository is currently available. This
repository will facilitate example re-use. The ability to re-use examples will
be leveraged in support of the TA standards development projects. Before the
end of the year, we will run a proof-of-concept that loads TAUG examples into
the SHARE MDR.
Early in 2015 the CDASH-to-SDTM mapping was generated for
eSHARE as part of the end-to-end standards work. By the end of the year we will
post a similar SDTM-to-ADaM carry over variables file for review. BCs will play
a key role in the development of end-to-end standards in 2016, and protocol
will be added prior to the end of 2016.
Finally, the SHARE team is working as a part of the Prostate
Cancer TA standards project to develop new tools in support of developing TA
standards. Starting with the Prostate Cancer project, SHARE tools will be used
to generate a draft TA Specification document containing the normative
standards. This is one of the clearest examples of SHARE supporting an
expedited TA standards development process. SHARE tools will also contribute to
the TA User Guides which include non-normative content such as examples from
the SHARE example repository. The Prostate Cancer TA standard project represents
an innovative first step towards using automation to drive a significant
portion of the standards development effort, and one that we will build upon in
future projects.
