Working with the XML data

Artist and other interested parties are free to use the data in the Connected OpenGreens database for their own projects under the creative commons license: Attribution-NonCommercial-ShareAlike.
All the data can be accessed through XML files which are created on the fly and therefore always up to date. To access the general garden data use the following URL: http://www.opengreens.okno.be/backend/xml/
By adding to this URL you can retrieve different and filtered data according to your needs. The structure is explained below.
To retrieve all the data from just one garden add the garden id to the URL: http://www.opengreens.okno.be/backend/xml/8. To view the data of just one element in the garden, add the id of that element to the URL: http://www.opengreens.okno.be/backend/xml/8/138
The garden elements are divided into classes. You can retrieve the data for one class for all the gardens with for example this URL: http://www.opengreens.okno.be/backend/xml/class/38 which will list the data for all the bee colonies in all the gardens. The database contains the following classes:
Id Name
26 nectar
25 pollen
27 layer
28 biotope
29 soilquality
30 plant_species
31 plant
32 square
33 square_monitoring
34 square_plant_monitoring
35 electronics
36 project
37 swarmcell_monitoring
38 bee_colony
39 electronic_type
41 people
42 animals
43 animal_type
You can extend the information for a class to view all the info about the subclasses (and subclasses of subclasses) in that class. By going for example to this URL: http://www.opengreens.okno.be/backend/xml/class/31/true This URL will not only show all the individual plant data but also names and images of the general plant species description. Going to http://www.opengreens.okno.be/backend/xml/class/30/true will list all the general plant data and the information of the subclasses which are the individual plants in this case. Play with the ‘true’ extension if you miss information using only the class id.
A last example, this URL: http://www.opengreens.okno.be/backend/xml/class/31/true/10 will give you the extended information on all the individual plants (class 30) in garden 10.

All XML is version 1.0 and UTF-8 encoded. Depending on the type of your application and the platform your using you may use for example xpath to filter the information further.

These XML files are generated mainly for use in this website. The possibilities of the database are much greater. So if you need other data or data in a different format for your project please contact opengreens[at]okno[dot]be and we'll try and accomodate you.
