A nice example of open data (in London).

Living in London, travelling using public transport is often the best way to get around. Before setting out on a journey one checks the status of the network. Doing so today I came across this page: our open data from Transport for London.

Goldilocks Data.

Last August, I wrote about data galore, the archival of data for 133,885 (134 kilo) molecules into a repository, together with an associated data descriptor[1] published in the new journal Scientific Data. Since six months is a long time in the rapidly evolving field of RDM, or research data management, I offer an update in the form of some new observations.

I remember a time when tracking down a particular property of a specified molecule was an all day effort, spent in the central library (or further afield). Then came the likes of STN Online (~1980) and later Beilstein. But only if your institution had a subscription. Let me then cut to the chase: consider this URL: http://search.datacite.org/ui?q=InChIKey%3DLQPOSWKBQVCBKS-PGMHMLKASA-N The site is datacite, which collects metadata about cited data! Most of that data is open in the sense that it can be retrieved without a subscription (but see here that it is not always made easy to do so). So, the above is a search for cited data which contains the InChIkey LQPOSWKBQVCBKS-PGMHMLKASA-N. This produces the result:
datacite1
This tells you who published the data (but oddly, its date is merely to the nearest year? It is beta software after all). The advanced equivalent of this search looks like this:
