Open data layer

In line with the principles of openness that we promote, the GODAN website is also available as open data.

All contents are exposed in machine-readable formats and accessible through open protocols.

The simplest way to get the contents for a machine is through RSS feeds. A more complex but more powerful way of accessing the contents is though a SPARQL endpoint.

1. RSS feeds

The mein RSS feed containing the latest 50 items published on GODAN is available at:
http://www.godan.info/rss/all-contents 

You can also filter the content appending additional parameters, using the following pattern:
http://www.godan.info/rss/updates/[resource type]/[topic/area]/[keyword]

E.g. to get only content that has to do with research:
http://www.godan.info/rss/updates/research

If you don't want to filter by one of the parameters, you can use the "all" placeholder:
e.g. to get content of any type about rights to data:
http://www.godan.info/rss/updates/all/all/rights-to-data

You can use the following values for the three parameters.

Parameter 1: resource type: advocacy-resource, case-study, dataset, discussion-paper, document, guidelines, media, presentation, press release, report, research, success-stories, think-piece, toolkit, white-paper

Parameter 2: area/topic: business-creation, food-security, gender-balance, nutrition-improvement, poverty-alleviation, sustainable-production, value-chain-improvement

Parameter 3: keyword: civil-society, government-data, linked-data, open-data, private-sector-data, public/private, rights-to-data, smes

2. RDF store and SPARQL endpoint

All the website content is also accessible as an RDF store. An RDF store is a way of storing data using a machine-readable "grammar" (the Resource Description Framework) and documented semantics (RDF vocabularies).

A detailed documentation of the RDF model and the Linked Data layer is in this document.

2a. URIs

Each piece of content has a URI where its RDF representation can be found. 
The URI for each piece of content (news item, blog post) or entity (organization, event) is built as follows: GODAN-domain/node/{node-ID}.
The URI for each concept (the various categories used in the website, like keywords, resource types etc.) is built as follows: GODAN-domain/taxonomy_term/{term-ID}.

2b. SPARQL endpoint

The whole RDF store is accessible through a SPARQL engine, which means that any system can run remote queries and get the resulting triples.

The endpoint of the SPARQL engine is:
http://www.godan.info/sparql/ 

2c. Vocabularies

The vocabularies used in the RDF store are:

2d. Sample queries

Query to get labels and URIs of all concepts used in the website:

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX schema: <http://schema.org/>
PREFIX dc: <http://purl.org/dc/terms/>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
DESCRIBE ?uri WHERE {
  ?uri rdf:type skos:Concept .
  ?uri skos:prefLabel ?label .
}

Query to get all the resources of type "Research":

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX schema: <http://schema.org/>
PREFIX dc: <http://purl.org/dc/terms/>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
DESCRIBE ?uri WHERE {
  ?uri dc:title ?title .
  ?uri dc:type <http://www.godan.info/taxonomy_term/350>
}
