Description
I have a GraphDB catalog for geospatial metadata that uses RDF to represent relationships between data. I want to expose this catalog via OGC API records but I realise that I cannot use pygeoapi because of lack of GraphDB(or graph databases-) support. There is a lot of increased use of linked data and graph databases are more relevant now more than ever. It would be icredible to enhance pygeoapi to support them.
Proposed Implementation
- Develop a new GraphDBCatalogue Provider class in pygeoapi/providers that extends the base provider architecture.
- Implement SPARQL queries to fetch and transform GraphDB records into OGC API - Records JSON format.
- Add configuration options in pygeoapi-config.yml for:
- GraphDB endpoint URL (e.g., http://localhost:7200/repositories/my_repo).
- Authentication credentials (if required).
- Custom` SPARQL query templates for record retrieval and filtering.
Suggestions.
On the other hand if anyone has a work around for using graph databases with pygeoapi please let me know.
