Requirements planning for next generation semantics infrastructure requires ongoing community input and visionary leadership to move into the next era of semantic computing. Refer to the Semantic Infrastructure Roadmap for further evolution of the Semantic Infrastructure. |

VCDE Requirements Elicitation Initiative
A small group from VCDE was formed to review and formally document requirements for the semantic infrastructure II
...
. Refer to the VCDE Requirements Elicitation Team Charter 2009.
In eliciting the software requirements for the semantic infrastructure, we have created common templates for collecting requirements and related use cases, and are following a common process.
Vocabulary Knowledge Center
...
Semantics Requirements Forum (VKC)
The community was asked to tell us what their requirements are for the next generation infrastructure and the VKC Semantics Requirement Forum was created for this purpose. Please feel free to visit the site and comment or
...
contribute additional ideas.
ICR Requirements are
...
on the Vocabulary Knowledge Center forum.
Background
The Semantic Infrastructure and Operations Group
...
is responsible
...
for the semantic aspects of the CORE Program Area, the caBIG® Vocabulary and Common Data Elements Workspace, and certain aspects of the
...
caBIG® Architecture Workspace, and caGrid®.
The activities of the NCI CBIIT Semantics and Operations Group fall into three areas:
- Content Management - the processes and procedures that ensure the breadth and quality of the metadata and terminology used to record the semantics of data meet the needs of the caBIG® community.
- Semantics Infrastructure - design and development
...
- of software resources and operations including producing reference implementations of platform independent models
- Semantics Architecture and Management - defining the platform independent (as also called "implementation Independent") specification for systems and processes required to meet the semantics needs of the CBIIT/
...
- caBIG® enterprise, and for assuring that operational requirements for semantics support are met
...
- in a timely and reliable way.
Our vision is to provide computational and human interpretable representation of the meaning and context of data and services. Realization of this goal is a vital to enable the caBIG® community to revolutionize biomedical research, personalized medicine, and integrated care.
...
To achieve this vision, the semantic infrastructure must:
...
- Continue to provide
...
- caBIG® with computationally tractable representations of the meaning and representation of data, and to extend semantic support to analytic and other services so that they can be discovered, understood, and securely utilized.
...
- Utilize a consistent, comprehensive information management discipline and software engineering standards such as ISO 10746 RM-ODP
...
- and its companion standard UML4ODP ISO 19793
...
- to define both enterprise semantics needs and implementation neutral solutions to meet those needs.
...
- Provide reference implementations of enterprise-level platform independent models addressing semantic needs, especially the need for behavioral semantics.
...
...
- Reduce the level of effort associated with creation of semantic information, in part by leveraging to the greatest extent possible automated approaches to harvest semantics information from line of business and software engineering activities.
Metadata
...
Management for Semantics Support
The semantic model and infrastructure forms a key component of the caBIG® collaborative infrastructure.
...
The current semantic infrastructure uses a modified version of ISO 11179 Ed2, which formed the seeds for the development
...
of ISO 11179 Ed3, and is the central component in allowing data elements and models to be annotated with concepts, and curated and registered in a repository allowing lookup and retrieval by both end-users and applications.
...
It enables the automatic integration and transformations of data for sharing and collaboration by provisioning the infrastructure with clear, computable, and unambiguous data descriptors for those who would create software that can use and interpret the data in the service of cancer research.
...
The
...
goal of the next generation infrastructure is to make these capabilities available to everyone with coarser-grained services that require little or no knowledge of the complexities of the
...
infrastructure in order to gain its benefits.
Two additional opportunities for
...
improvement in the current
...
infrastructure approach are:
1) simplify the creation of this metadata which is
...
currently labor intensive and therefore does not scale well
2) expand
...
the approach beyond data discovery and interchange, to
...
include services interoperability
Interested Parties
...
and Stakeholders in New Semantic Infrastructure
The key to success for the next generation infrastructure is defining the critical, unmet semantic interoperability usage scenarios to ensure that the right next generation of services and infrastructure are provisioned.
...
With the help of Mayo Clinic through the
...
Vocabulary Knowledge Center
...
this wiki to support requirements gathering
...
was organized to collect and report on requirements.
...
Interested parties are encouraged to become involved over the next few months as we attempt to characterize in more detail the requirements to achieve the interoperability vision.
Primary Users
...
The primary direct and indirect end users include:
- Software and Application designers and architects
- Software and Application engineers and developers
- Scientific and medical researchers
- Medical research protocol designers
- Clinical and scientific research data managers
- Clinicians
- Patients
- Medical research study
...
- participants
