SSSOM-API

The Simple Standard for Sharing Ontological Mappings (SSSOM) API is a tool for accessing ontological mappings between different ontologies.

SSSOM API locally

You can run the API locally using Docker:

1. docker-compose up --build

This will start the three services:

1. The API itself (service api)
2. Triplestore RDF4J (service triplestore)
3. Upload data into the triplestore (service upload-triplestore)

After the service upload-triplestore finish and stops, you can access the SSSOM API at localhost:8008/docs.

You can access the triplestore at localhost:8080/rdf4j-workbench.

Endpoints

The SSSOM API is designed to be easy to use and has the following endpoints:

/entities

POST endpoint to retrive all mappings with CURIE as subject_id or object_id and optionally filtering by mapping justification and predicate id.

The request body is

{
  "curies": [
    "string"
  ],
  "mapping_justification": [
    "string"
  ],
  "predicate_id": [
    "string"
  ]
}

Only the object curies is required.

/mappings/?filter

Retrieve all mappings in the triplestore. It's possible to filter your results using the filter. The filter pattern is [field]|[operator]|[value].

For the complete list of fields, check here.

The list of operators is:

Operator	Description
ge	greater than or equal to
gt	greater than
le	less than or equal to
lt	less than
contains	contains

/mappings/{field}/{value}

Retrieve the mappings with field=value. Check here to see the complete list of fields/slots for a mapping.

/mappings/{id}

Retrieve a mapping by its id.

/mapping_sets

Retrieve the mapping_sets in the triplestore.

/mapping_sets/{id}/mappings

Retrieve the mappings for a mapping set.
