WS-Calendar standard out for Public Review

The OASIS Web Services Calendar (WS-Calendar) Technical Committee produced an Committee Specification Draft which is now out for Public Review.

The WS-Calendar specification describes how to specify a sequence of services, how to schedule them, and how to invoke them. The specification was developed to support use cases in smart grids and smart energy, but it supports any sort of coordinated activities between domains. The committee explicitly considered coordination between energy coordination, enterprise systems, building systems, and financial markets. The specification also defines a conforming model for inheritance to reduce duplication of expression when similar services are requested in a recurring schedule.

The specification adapts the existing specifications for calendaring and apply them to a new specification for how schedule and event information is passed between and within services. The standard adopts the semantics and vocabulary of iCalendar for application to the completion of web service contracts. WS Calendar builds on work done and ongoing in The Calendaring and Scheduling Consortium (CalConnect), which works to increase interoperation between calendaring systems, and the Internet Engineering Task Force (IETF).

EU strategy for Cloud

Recently I wrote an opinion piece for (the Dutch) online IT magazine Computable.nl about EU commissionar Neelie Kroes' new European Cloud Computing Strategy.

Her speech, "European Cloud Computing Strategy needs to aim high", was delivered at the Opening of Microsoft Centre on Cloud Computing and Interoperability  in Brussels, 22 March 2011. Kroes highlighted the importance of standardisation and the involvement from public actors and industry. Kroes went on to restate the three pillars for a cloud strategy. Firstly, a legal framework, addressing users' rights, data protection and privacy issues; secondly, technical and commercial fundamentals to boost research efforts on security and reliability;  and thirdly, the market, supporting both industry and public actors.

In my article I elaborate on the fact that this new strategy is something we should embrace and give some practical examples on each of the three pillars.
