- The DOKK is a free database. The data is modeled as a graph, with topics represented
- as nodes connected by edges.
- Naming conventions
- ------------------
- Because the graph contains a large number of nodes, it's divided into more manageable
- subgraphs (one per folder).
- There are no restrictions on the ID values that can be used, but in order to keep
- things well organized the following conventions are adopted:
- dokk:subgraph:id
- | | |_____ local ID, defined within the subgraph
- | |______________ name of the subgraph where the node is defined
- |___________________ fixed prefix
- Using the graph
- ---------------
- Files can be parsed with any RDF library. For more advanced needs the files can
- be loaded in a database server (a triplestore). For this we recommend the Fuseki
- server.
- Following is a demonstration with Python and RDFLib:
- g = rdflib.Graph()
- g.parse("file-1")
- g.parse("file-2")
- g.parse("...")
- # Execute queries on the graph.
- # (example: find the names of the people that know Bob
- query = """
- SELECT ?name
- WHERE { ?person :knows :bob ;
- :name ?name . }
- """
- results = g.query(query)
- for r in results:
- print(r.name)
-
- # Or convert nodes to JSON
- graph_json = json.loads(g.serialize(format="json-ld"))
- Contacts
