Continuing the Friday folly theme, below is a screencast of a linked data browser that uses the same ideas as last week's screencast, but uses a custom browser I've written to display the results in a more user-friendly way. Linking the data together from Roderic Page on Vimeo. The demo is live, you can view it at http://iphylo.org/~rpage/browser/www/uri/http://bioguid.info/doi:10.1371/journal.pone.0001787.

Time for a Friday folly. I've made a clunky screencast showing an example of linking biodiversity data together, using bioGUID as the universal wrapper around various data sources. I started with GenBank sequence EF013683, added another, EF013555, then explored some links (specimen, publication, taxon, journal), using the OpenLink RDF Browser: Linking biodiversity data from Roderic Page on Vimeo.

I'm in the midst of rebuilding iSpecies (my mash-up of Wikipedia, NCBI, GBIF, Yahoo, and Google search results) with the aim of outputting the results in RDF. The goal is to convert iSpecies from a pretty crude "on-the-fly" mash-up to a triple store where results are cached and can be queried in interesting ways. Why?

A Semantic blog is one in which the system at least in part understands about (some of the) concepts and topics that are in the content. The idea is that this content can be more intelligently (is that the correct word?) and importantly, automatically searched, harvested, and connected to the same or similar concepts found elsewhere in other blogs and the Web as whole.

Following on from the last post, I've now set up a trivial NCBI RDF service at bioguid.info/taxonomy/ (based on the ISSN resolver I released yesterday and announced on the Bibliographic Ontology Specification Group). If you visit it in a web browser it's nothing special. However, if you choose to display XML you'll see some simple RDF.

Lately I've been returning to playing with RDF and triple stores. This is a serious case of déjà vu, as two blogs I've now abandoned will testify (bioGUID and SemAnt). Basically, a combination of frustration with the tools, data cleaning, and the lack of identifiers got in the way of making much progress.

Nothing like a little hubris first thing Monday morning... After various experiments, such as a triple store for ants (documented on the Semant blog) and bioGUID (documented on the bioGUID blog), I'm starting from scratch and working on a "database of everything". Put another way, I'm working on a database that aggregates metadata about specimens, sequences, literature, images, taxonomic names, etc.

Following on from the previous post, as Howison and Goodrum note, Adobe provides XMP as a way to store metadata in files, such as PDFs. XMP supports RDF and namespaces, which means widely used bibliographic standards such as Dublin Core and PRISM can be embedded in a PDF, so the article doesn't become separated from its metadata. Adobe provides a developers kit under a BSD license.
