Requirements

Python 3.14+
Invenio 14.x
OpenSearch/Elasticsearch compatible search backend

Key Features

1. Model Registry and Management

Source: oarepo_runtime/api.py, oarepo_runtime/ext.py, oarepo_runtime/config.py

The Model class provides a unified configuration structure for record types in your repository:

from oarepo_runtime import Model
from flask_babel import lazy_gettext as _

model = Model(
    code="my_record",
    name=_("My Record Type"),
    version="1.0.0",
    service="my_records",
    resource_config="my_app.resources.config.MyRecordResourceConfig",
    description=_("Custom record type for my repository"),
    exports=[
        Export(
            code="datacite",
            name=_("DataCite JSON"),
            mimetype="application/vnd.datacite.datacite+json",
            serializer=DataCiteSerializer(),
        )
    ],
    records_alias_enabled=True,
)

Normally, it is created automatically when using the oarepo-model library.

The OARepoRuntime extension manages all registered models:

from oarepo_runtime import current_runtime

# Access models by code
model = current_runtime.models["my_record"]

# Get service for a record instance
service = current_runtime.get_record_service_for_record(record)

# Find records by PID type
record_class = current_runtime.record_class_by_pid_type["recid"]

# Get all RDM-compatible models
rdm_models = list(current_runtime.rdm_models)

Key capabilities:

Centralized model registration via OAREPO_MODELS configuration
Automatic service and resource resolution
PID type to record class mapping
Schema to model mapping for serialization
Support for draft/published record workflows
File service integration

2. Enhanced System Fields

Source: oarepo_runtime/records/systemfields/

Typed System Fields

Base class for system fields with type hints and proper typing support:

from oarepo_runtime.records.systemfields import TypedSystemField


class MyCustomField(TypedSystemField[MyRecord, str]):
    def obj_get(self, record: MyRecord) -> str:
        # Implementation
        pass

Mapping System Fields

Dynamic OpenSearch mapping support for system fields that need custom indexing:

from oarepo_runtime.records.systemfields import MappingSystemFieldMixin


class DynamicField(MappingSystemFieldMixin, TypedSystemField):
    def mapping_settings(self, record_class):
        return {"type": "keyword", "eager_global_ordinals": True}

Publication Status System Field

Built-in field for tracking record publication status:

from oarepo_runtime.records.systemfields import PublicationStatusSystemField


class MyRecord(Record):
    publication_status = PublicationStatusSystemField()

3. Advanced Faceting System

Source: oarepo_runtime/services/facets/

Date Range Facets

Support for date-based faceting with configurable intervals:

from oarepo_runtime.services.facets.date import DateRangeFacet

facets = {"created": DateRangeFacet(field="created", label="Created Date", interval="year")}

Nested Facets

Faceting on nested objects with label resolution:

from oarepo_runtime.services.facets.nested_facet import NestedLabeledFacet

facets = {
    "contributors": NestedLabeledFacet(
        field="metadata.contributors.person.id",
        nested_path="metadata.contributors",
        value_labels={"person123": {"cs": "Jan Novák", "en": "Jan Novak"}},
    )
}

Grouped Facets with Permissions

Permission-based facet grouping for different user roles:

from invenio_records_resources.services.records.config import SearchOptions
from invenio_records_resources.services.records.facets import TermsFacet


class MySearchOptions(SearchOptions):
    facets = {
        "publication_status": TermsFacet(field="publication_status"),
        "internal_status": TermsFacet(field="internal_status"),
        "workflow_state": TermsFacet(field="workflow_state"),
    }

    facet_groups = {
        "default": ["publication_status"],
        "admin": ["internal_status", "workflow_state"],
    }

4. Service Component Ordering

Source: oarepo_runtime/services/config/components.py

Deterministic ordering of service components with dependency resolution:

class ComponentOrderingMixin:
    """Mixin that ensures service components execute in the correct order."""

    @property
    def components(self):
        # Components are automatically ordered based on:
        # - depends_on declarations
        # - affects declarations
        # - wildcard semantics (*)
        # - input order preservation where possible
        return self._ordered_components

Components can declare dependencies:

class MyComponent(ServiceComponent):
    depends_on = [ValidationComponent]  # Runs after ValidationComponent
    affects = "*"  # Affects all subsequent components

5. Multilingual Support

Source: oarepo_runtime/services/schema/

I18N UI Schema Support

Marshmallow schemas with multilingual field support:

from oarepo_runtime.services.schema.i18n_ui import I18nUISchema, MultilingualUIField


class MyUISchema(I18nUISchema):
    title = MultilingualUIField()
    description = MultilingualUIField(
        ui_params={"widget": "textarea", "placeholder": {"en": "Enter description", "cs": "Zadejte popis"}}
    )

Locale Handling

from oarepo_runtime.services.schema.i18n import LocalizedDateTime


class RecordSchema(Schema):
    created = LocalizedDateTime()  # Automatically formats dates per locale

6. Signposting and FAIR Data

Source: oarepo_runtime/resources/signposting/

Full implementation of FAIR Signposting for machine-readable links:

from oarepo_runtime.resources.signposting import landing_page_signpost_links_list, create_linkset, create_linkset_json

# Generate signposting links for a landing page
links = landing_page_signpost_links_list(datacite_dict, record_dict, short=False)

# Create HTTP Link header
header = list_of_signpost_links_to_http_header(links)

# Create application/linkset format
linkset = create_linkset(datacite_dict, record_dict)

# Create application/linkset+json format
linkset_json = create_linkset_json(datacite_dict, record_dict)

Supported relation types:

author - Links to author identifiers
cite-as - Persistent identifier (DOI)
describedby - Metadata export formats
item - File contents
license - License URIs
type - Resource type (schema.org)

7. Repository Information API

Source: oarepo_runtime/info/views.py

Machine-readable endpoint for repository metadata:

# GET /.well-known/repository
{
    "models": {
        "my_record": {
            "code": "my_record",
            "name": "My Record Type",
            "version": "1.0.0",
            "links": {
                "html": "/my-records/",
                "records": "/api/my-records/",
                "deposit": "/api/my-records/",
                "drafts": "/api/user/my-records/",
            },
            "jsonschemas": {"record": "https://localhost/schemas/my-records-1.0.0.json"},
            "exports": [{"code": "datacite", "mimetype": "application/vnd.datacite.datacite+json"}],
        }
    }
}

8. CLI Extensions

Source: oarepo_runtime/cli/

Enhanced search index initialization:

# Initialize search indices with custom field mapping updates
invenio index init

# The init command automatically runs registered hooks from:
# - oarepo.cli.search.init entry point
# - Updates dynamic mappings for all registered models

Extension point for custom initialization:

# In your package's entry points:
[project.entry-points."oarepo.cli.search.init"]
my_init = "my_app.init:update_custom_mappings"

9. Custom Fields and Relations

Source: oarepo_runtime/services/records/

Support for updating record mappings with custom fields:

from oarepo_runtime.services.records.custom_fields import update_all_records_mappings_relation_fields

# Update OpenSearch mappings for all records with relation fields
update_all_records_mappings_relation_fields()

10. Permission Generators

Source: oarepo_runtime/services/config/permissions.py

Pre-configured permission policy for open access repositories:

from oarepo_runtime.services.config.permissions import EveryonePermissionPolicy


class MyServiceConfig(RecordServiceConfig):
    permission_policy_cls = EveryonePermissionPolicy
    # Grants all permissions to any authenticated or anonymous user
