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?

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.
