The title of this post comes from the site www.crossref.org/members/prep/ Here you can explore how your favourite publisher of scientific articles exposes metadata for their journal. Firstly, a reminder that when an article is published, the publisher collects information about the article (the “metadata”) and registers this information with CrossRef in exchange for a DOI.

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.  I learnt that by making TFL travel data openly available, some 11,000 developers (sic!) have registered for access, out of which some 600 travel apps have emerged.

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[cite]10.1038/sdata.2014.22[/cite] 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.

My name is displayed pretty prominently on this blog, but it is not always easy to find out who the real person is behind many a blog. In science, I am troubled by such anonymity.

I blogged about this two years ago and thought a brief update might be in order now. To support the discussions here, I often perform calculations, and most of these are then deposited into a DSpace digital repository, along with metadata. Anyone wishing to have the full details of any calculation can retrieve these from the repository. Now in 2012, such repositories are more important than ever.

Sometimes, as a break from describing chemistry, I take to describing the (chemical/scientific) creations behind the (WordPress) blog system. It is fascinating how there do seem increasing signs of convergence between the blog post and the journal article. Perhaps prompted by transclusion of tools such as Jmol and LaTex into Wikis and blogs, I list the following interesting developments in both genres.
