geosparqllib

A Python functions library for working with GeoSPARQL data.

Project home: https://github.com/Kurrawong/geosparqllib/

This Python library contains a series of functions for creating, using and otherwise working with GeoSPARQL RDF data.

Common tasks handled by this library are:

• creating GeoSPARQL data from other spatial data
• ...

Installation

This library is available on PyPI so can be installed using PIP:

pip install geosparqllib

or Poetry:

poetry add geosparqllib

Use

Here's an example of using the make_geometry() function:

from geosparqllib import make_geometry

j = """
    {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Polygon", 
        "coordinates": [
          [ 
            [0, 0], 
            [1, 0], 
            [1, 1], 
            [0, 1], 
            [0, 0] 
          ]
        ]
      }
    }
    """
f = "http://example.com/f/1"
geom, bn = make_geometry(f, j)
print(geom.serialize(format="longturtle"))

returns:

PREFIX geo: <http://www.opengis.net/ont/geosparql#>

<http://example.com/f/1>
    geo:hasGeometry
        [
            a geo:Geometry ;
            geo:asWKT "POLYGON ((0 0, 1 0, 1 1, 0 1, 0 0))"^^geo:wktLiteral ;
        ] ;
.
