API for data archiving.

Earlier this year, the Tennessee Valley Authority (TVA) announced that it open sourced its data system used to collect data from smart grid devices called Phasor measurement units (PMUs). The data collection system is known in the industry as a Super Phasor Data Concentrator (SuperPDC), which can be used to determine the health of a power grid. The open-source version of the SuperPDC is now called the "OpenPDC." I spoke to both Ritchie Carroll (RC), the project's creator, and Josh Patterson (JP), the person responsible for introducing Hadoop to the project, to discuss what the OpenPDC is and why TVA turned to Hadoop in building the system. What sort of data volumes are you working with? RC: Currently there is around 20 TB of archived data, we expect this to grow quickly as a result of the SmartGrid stimulus funding which includes the addition of 850 phasor measurement devices. This may well grow the archive to half a Petabyte within the next few years.

Go is … … simple package main import "fmt" func main() { fmt.Printf("Hello, 世界\n") } … fast Go compilers produce fast code fast. Typical builds take a fraction of a second yet the resulting programs run nearly as quickly as comparable C or C++ code. … safe Go is type safe and memory safe. Go has pointers but no pointer arithmetic. For random access, use slices, which know their limits. … concurrent Go promotes writing systems and servers as sets of lightweight communicating processes, called goroutines, with strong support from the language. Run thousands of goroutines if you want—and say good-bye to stack overflows. … fun Go has fast builds, clean syntax, garbage collection, methods for any type, and run-time reflection. It feels like a dynamic language but has the speed and safety of a static language. It's a joy to use. … open source

"I've always been a huge fan of Astoria, which is the RESTful [Representational State Transfer] front end to the relational capability," Gall said. "Now with 'Oslo' you can take virtually any kind of data model and then expose it RESTfully -- without having to do a lot of laborious 'RESTifying' of the process."

Public Sector Information Architecture An information architecture is vital to ensuring that information and data can flow across government to provide seamless, efficient, secure and trusted services. It also provides opportunities for the re-use of non-personal public data, helping to fuel innovation. URI sets will be an integral component of a UK Public Sector Information Architecture. URI sets can be published by the UK public sector to provide comprehensive and reliable identifiers for ‘Things’ such as schools, roads, legislation, locations, projects, events and so on. Where the quality of these sets can be described consistently, other data owners will have the confidence to re-use them in their own data, leading to a web of data that can be linked, queried, and aggregated.
