This blog started in january 2009. Before starting it I sent a PM to the general directors of a large number of national statistical offices that usually are active in the international statistical metadata circuit. The title of this PM was “The Metadata Fallacy – What all general directors should know about statistical metadata”, and its content briefly described the first two of five “key insights”.

Key insights are what statistical metadata experts should have, but do not have, and therefore keep doing the wrong things in the wrong way. Now, at least, their general directors have a first inkling about what has gone wrong, and therefore also the power to change things to the better.

This blog will help them along with this, by giving more concrete examples of how their experts have been, and still are, doing the wrong things in the wrong way, and what the general directors can do about it.

After the 2010 UNECE/METIS and SDMX expert group meetings this blog has become an archive. However, one or two posts may be added if something interesting happens.

I have also published the first framework for statistical metadata. You can download it from this blog. However, remember that it can be replaced by five key insights, a handful of modelling insights and a six page strategy document.

The most recent addition is documentation that describes the Abelin model for an NSO classification management system. The first truly standard statistical metadata model. You can download it from this site.

By the way, did I mention that the issues thay they are trying to solve have in large parts already been solved? In fact, 80% has already been solved by the regular IT-industry. You only have to know how to identify it and adapt it.

During 2011 I have temporarily restarted the blog. The reasons for this have been the increasing SDMX hype (and signs of failure) and the GSIM modelling project.

What is GSIM? Maybe the fifth attempt during the last ten years to develop a common reference model. Do you think that they will succeed?
