In recent years we have seen a rapid growth is the deployment of smart technologies in communities. As the number of services grows it becomes necessary to think about interoperability of services within communities and portability of services between communities. 
Smart communities use data and technology to help drive efficiencies, improve sustainability, spur economic development, and enhance the quality of life for their citizens. These benefits can not be achieved if this data is trapped in service silos. 

“Two barriers currently exist to effective and powerful smart city solutions. First, many current smart city ICT deployments are based on custom systems that are not interoperable, portable across cities, extensible, or cost-effective. Second, a number of architectural design efforts are currently underway (e.g. ISO/IEC JTC1, IEC, IEEE, ITU and consortia) but have not yet converged, creating uncertainty among stakeholders.”

NIST International Technical Working Group on IoT-Enabled Smart City Framework
The NIST International Technical Working Group on IoT-Enabled Smart City (IES City) Framework convened to compare and distill the work of the many architectural design efforts currently underway and working with city stakeholders develop a consensus framework of common architectural features to enable smart city solutions that meet the needs of modern communities.

The working group defined Pivotal Points of Interoperability (PPI) to enable agreement on somethings not everything. If you standardize everything, you freeze out innovation. If you standardize nothing, you get non-interoperable clusters that can’t be easily integrated. Defining the principle of Pivotal Points of Interoperability is to find consensus standardized interfaces that deal with composition without constraining innovation.
Open Source allows for the ready availability of reusable building blocks. Zones of concern can be assembled for offering using these components. The availability of well understood building blocks encourages an ecosystem of deployers, operators, and maintainers for smart city apps. These together minimize the barriers to penetration of smart technologies to benefit communities.
OpenCommons is a 501(c)6 non-profit organization of like minded members working to implement reusable code blocks. Members include deployers, operators, and maintainers interested in supporting communities. Commercial equipment, software and device suppliers interested in growing the marker of communities capable of deploying their products. Communities interested in being able to influence the development of services to support residents, businesses and staff.
OpenCommons has working groups collaborating on new services, developing critical policies, recommending procedures and sharing best practices. If you are interested in becoming members of this community please fill in this form.
