Prez v4.0.0

[recalcitrantsupplant]

• Simplified to define two main functions (for listings and objects), on which all "instance data" endpoints are based.
• Utilises external SPARQL grammar Pydantic library to build SPARQL queries (https://pypi.org/project/sparql-grammar-pydantic/)
  • This provides the basis for safely merging CQL, Search, Endpoint defined classes, and profiles to generate queries.

Listing Endpoints

The "instance data" listing endpoints are:

1. /profiles
2. /catalogs
3. /catalogs/{catalogId}/collections
4. /catalogs/{catalogId}/collections/{collectionId}/items
5. /concept-hierarchy/{parent_uri}/top-concepts
6. /concept-hierarchy/{parent_uri}/narrowers
7. /search?q=<search term/>
8. /cql?filter=<CQL JSON expression>

All of these endpoints share the same FastAPI Dependency instances:

• CQL (implemented as a selection/filter of focus nodes within the SubSelect)
• Search (regex search)
• Endpoint nodeshapes (which focus nodes to select at a given endpoint, given any parents)

Object Endpoints

The "instance data" object endpoints are:

1. /object?uri=<uri>
2. /profiles/{profile_curie}
3. /catalogs/{catalogId}
4. /catalogs/{catalogId}/collections/{collectionId}
5. /catalogs/{catalogId}/collections/{collectionId}/items/{itemId}

Additional management and other endpoints are provided, the details of which can be seen in the OpenAPI docs at /docs.
