Rijkswaterstaat Linked Data Tools

Scripts

• mkschema - extracts the DB's schema and generates a prototype ontology template
• mkontology - converts an ontology template to valid OWL
• mkgraph - convert a DB to knowledge graph using the supplied OWL ontology
• mkextra - enrich supplied knowledge graph with third-party data (eg, geo)
• mkxrefs - generate cross references between supplied knowledge graphs
• mkotl - generate OTL references in supplied knowledge graph
• mkmerger - merge supplied knowledge graphs

Note that

1. database schemas and dumps are property of Rijkswaterstaat and are not included
2. mkschema requires restricted Rijkswaterstaat UML diagrams in some cases
3. mkgraph requires an OWL ontology to function

Example

To generate a schema

$ python mkschema.py --server "<username>:<password>@<host:port>/<database>/<user>" --output <database>.json --datatype_schema datatypes.json

To convert a DB to knowledge graph

$ python mkgraph.py --server "<username>:<password>@<host:port>/<database>/<user>" --area "<X0> <Y0> <X1> <Y1>" --datatype_schema <database>.json --output <database>.ttl
