cluedin 3.0.0

CluedIn Python SDK

CluedIn

cluedin is a Python SDK for CluedIn API.

Installation

From PyPi:

pip install cluedin

Quick start

CluedIn context configuration

Create a JSON file with context configuration to your CluedIn instance:

In this file, parameters have the following meaning:

• protocol - http if your CluedIn instance is not secured with a TLS certificate. Otherwise, https by default.
• domain – CluedIn instance domain without the Organization prefix.
• org_name – the name of Organization (a.k.a. Organization prefix).
• user_email – the user's email.
• user_password – the user's password.
• verify_tls – false, if an unknown CA signs the TLS certificate. Otherwise, true by default.

Here is an example of a file for a CluedIn instance running locally from a Home repository:

{
  "domain": "mdm.saas-cluedin.com",
  "org_name": "foobar",
  "user_email": "[e-mail]",
  "user_password": "Foobar23!"
}

We add the protocol, but we can skip this parameter if the URL starts with https. If you use self-signed certificates, you can add verify_tls: false to avoid certificate verification.

Alternatively, to provide email and password, you can obtain an API access token from CluedIn UI and provide it in the file:

{
  "domain": "mdm.saas-cluedin.com",
  "org_name": "foobar",
  "access_token": "..."
}

When the configuration file exists, you can export its path to an environment variable:

export CLUEDIN_CONTEXT=~/.cluedin/home.json

Now, you can load this file from your Python code and get an access token (if not already provided):

import cluedin

context = Context.from_json_file(os.environ['CLUEDIN_CONTEXT'])
context.get_token() # call it only if access_token is not provided in the context file

You could also do it without the context file:

context = {
    "domain": "mdm.saas-cluedin.com",
    "org_name": "foobar",
    "user_email": "[e-mail]",
    "user_password": "Foobar23!"
}

context = Context.from_dict(context)
context.get_token()

Or, you can infer the context from the JWT token:

context = Context.from_jwt(API_TOKEN)

GraphQL

Get entities:

context = Context.from_json_file(os.environ['CLUEDIN_CONTEXT'])
context.get_token()

query = """
    query searchEntities($cursor: PagingCursor, $query: String, $pageSize: Int) {
      search(
        query: $query,
        sort: FIELDS,
        cursor: $cursor,
        pageSize: $pageSize
        sortFields: {field: "id", direction: ASCENDING}
      ) {
        totalResults
        cursor
        entries {
          id
          name
          entityType
        }
      }
    }
"""

variables = {
    "query": "*",
    "pageSize": 10_000
}

# it's important to request cursor in your GraphQL query,
# so cluedin.gql.entries would be able to request and return all pages
entities = cluedin.gql.entries(context, query, variables):

API

Environment

• CLUEDIN_REQUEST_TIMEOUT_IN_SECONDS - CluedIn API request timeout (in seconds). If not set, then it defaults to 300 (5 minutes).

Context

• cluedin.Context.from_dict(cls, context_dict: dict) -> Context – creates a new Context object from a dict.
• cluedin.Context.from_json_file(file_path: str) -> Context – creates a new Context object from a JSON-file.
• cluedin.Context.from_jwt(jwt: str) -> Context – creates a new Context object from a JWT (JSON Web Token, a.k.a. access token or API token).

Account

• cluedin.account.get_users(context: Context, org_id: str = None) -> list – returns all users for Organization.
• cluedin.account.is_organization_available_response(context: Context, org_name: str) -> dict – checks if a given Organization name is available. This method returns a JSON-response serialized into a dict.
• cluedin.account.is_organization_available(context: Context, org_name: str) -> bool – checks if a given Organization name is available. Returns a Boolean.
• cluedin.account.is_user_available_response(context: Context, user_email: str, org_name: str) -> dict – checks, if a user with a given email can be created or this email is already reserved. This method returns a JSON-response serialized into a dict.
• cluedin.account.is_user_available(context: Context, user_email: str, org_name: str) -> bool – checks, if a user with a given email can be created or this email is already reserved. This method returns a JSON-response serialized into a dict. Returns a Boolean.
• cluedin.account.get_invitation_code(context: Context, email: str) -> str – returns an invitation code for a given email.
• cluedin.account.create_organization(context: Context, user_email: str, password: str, org_name: str, org_sub_domain: str = None, email_domain: str = None, allow_email_domain_signup: bool = True, new_account_access_key: str = None) -> dict - creates a new Organization. This method returns a JSON-response serialized into a dict.
• cluedin.account.create_user(context: Context, user_email: str, user_password: str) -> requests.models.Response – creates a new user. This method returns requests.models.Response.
• cluedin.account.create_admin_user(context: Context, user_email: str, user_password: str) -> requests.models.Response – creates a new admin user. This method returns requests.models.Response.
• cluedin.account.get_user(context: Context, user_id: str = None) -> dict – returns a user by ID. If user_id is nor provided, the current user is returned. This method returns a JSON-response serialized into a dict.

Entity

• cluedin.entity.get_entity_blob(context: Context, entity_id: str) -> str – returns an entity blob by ID.
• cluedin.entity.get_entity_as_clue(context: Context, entity_id: str) -> str – returns an entity as a clue by ID.

Ingestion

• cluedin.ingestion.post(context: Context, url: str, collection: list[Any], batch_size: int = 10_000, delay_in_seconds: int = 0) -> Generator – posts data to CluedIn ingestion endpoint. This method splits the collection into batches and sends them to CluedIn. If delay_in_seconds is set, then it waits for this time before sending the next batch. Returns a generator of responses.

GraphQL

• cluedin.gql.gql(context: Context, query: str, variables: dict = None) -> dict – sends a GraphQL request and returns a response.
• cluedin.gql.org_gql(context: Context, query: str, variables: dict = None) -> dict – sends a GraphQL request to Organization endpoint and returns a response.
• cluedin.gql.entries(context: Context, query: str, variables: dict = None, flat=False) -> Generator – returns entries from a GraphQL search query. If cursor is requested in the GraphQL query (see the example above and tests), then it proceeds to next pages to return all results. If flat is True, then it flattens the properties dictionary of each returned entity.
• search(context: Context, search_query: str, page_size: int = 10_000) -> Generator – returns entities by a search query. This method is a wrapper around cluedin.gql.entries.

JSON

• cluedin.json.dump(file: str, obj: Any) -> None – serialize obj as a JSON formatted stream to file.
• cluedin.json.load(file: str) -> Any – deserialize file to a Python object.

JWT

• cluedin.jwt.get_jwt_payload(jwt: str) -> dict – parses a JWT (JSON Web Token, a.k.a. access token or API token), and returns its payload serialized into a dict.

Public API

• cluedin.public.post_clue(context: Context, clue: str, content_type: str = 'application/xml') -> str – posts a clue in XML or JSON format. This method returns an operation result as a string.
• cluedin.public.restore_user_entities(context: Context) -> list – if you accidentally deleted /Infrastructure/User entities, this method gets all users and restores entities for those who miss them.

Rules

• cluedin.rules.RuleScope - an enumeration of rule scopes: DATA_PART, ENTITY, SURVIVORSHIP.
• cluedin.rules.get_rules(context: Context, scope=RuleScope.DATA_PART) -> dict – returns all rules for a given scope. This method returns a JSON-response serialized into a dict.
• cluedin.rules.get_rule(context: Context, rule_id: str) -> dict – returns a rule by ID. This method returns a JSON-response serialized into a dict.

Evaluator

• cluedin.rules.evaluator.default_get_property_name(field: str) -> str – returns a default property name for a given field. Used to map CluedIn Rules fields to your fields.

• cluedin.rules.evaluator.default_get_value(field: str, obj: dict) -> Any – returns a default value for a given field. Used to map CluedIn Rules fields to your fields.

• cluedin.rules.Evaluator – a class to evaluate CluedIn Rules.

• cluedin.rules.Evaluator.evaluate(context: Context, rule: dict, obj: dict) -> bool – evaluates a rule for an object. Returns a Boolean:

  • cluedin.rules.get_matching_objects(self, objects) -> list – returns a list of objects that match the rule.
  • cluedin.rules.object_matches_rules(self, obj) -> bool – returns True if an object matches the rule.
