DC Terms data model for oarepo.


    pip install oarepo-dc


The library provides Dublin Core object for json schema with marshmallow validation and deserialization and elastic search mapping.

JSON Schema

Add this package to your dependencies and use it via $ref in json schema as "[server]/schemas/dcterms-v2.0.0.json#/definitions/DCObject". Elastic Search mapping is handled automatically via Eleastic Search templates.

Usage example

  "$schema": "",
  "type": "object",
  "properties": {
    "these": {
            "$ref": "https://localhost:5000/schemas/dcterms-v2.0.0.json#/definitions/DCObject"
  "type": "object",
  "properties": {
    "these": {
        "abstract" : {"cs": "neco", "en": "something"}, 
        "contributor" : "Alzbeta Pokorna", 


For data validation and deserialization.

If marshmallow validation is performed within application context, languages in multilingual string data fields are validated against SUPPORTED_LANGUAGES config. If the validation is performed outside app context, the keys are not checked against a list of languages but a generic validation is performed - keys must be in ISO 639-1 or language-region format from RFC 5646.

Usage example

class MD(DCObjectSchemaV2Mixin, marshmallow.Schema):

data = {"title": {"cs": "neco"},
                 "alternative": {"en-us": "something", "cs": "neco"},
                 "abstract": {},
                 "creator": "Alzbeta Pokorna",
                 "contributor": "Miroslav Simek",
                 "dateSubmitted": "1970-10-12",
                 "available": "1970-03-18",
                 "created": "1970-09-29",
                 "modified": "1970-12-31",
                 "description": {"en-us": "something", "cs": "neco"},
                 "identifier": "id"}


Supported languages validation

You can specified supported languages in your application configuration in SUPPORTED_LANGUAGES . Then only these languages are allowed as multilingual string. You must specified your languages in format "en" or "en-us".

Usage example

app.config.update(SUPPORTED_LANGUAGES = ["cs", "en"])
