Linked Data for Barrington Atlas Grids

Pleiades often refers to Barrington Atlas grid cells and now there is supporting linked data

Pleiades has currently 8205 roughly located places. Some of these are ones that haven't been matched to objects captured from the map sheets by DARMC, some have no known locations, and some have locations that Pleiades is not going to represent precisely: the extents of the Atlantic Ocean or the territory of the Volcae Arecomici are intrinsically fuzzy. Instead of providing coordinates, Pleiades locates these things via relationships to the Barrington Atlas grid cells. Looking in the RDF data (previously on this blog) about the Internum Mare, you will see that its location is attested to be within cells G4 and I4 of map 1.

<http://pleiades.stoa.org/places/1043#this> a <http://geovocab.org/spatial#Feature>;
    rdfs:label "Internum Mare";
    osspatial:within <http://atlantides.org/capgrids/1#G4>,
        <http://atlantides.org/capgrids/1#I4>;

The URIs identifying the map grids now resolve to HTML or RDF documents. Additionally, data from all grids in a single file are available from the CAP Grids dataset on CKAN.

The grid data is accessed from a Python package named capgrids and the web resources were written using capgrids-web and rdflib.
