Data model

The Radical Translations project data model is based on BIBFRAME, for Resources (Works, Instances, Items are flattened under one object type) and Events, and based on FOAF for Agents (Persons, Organisations).

Django models

Django models

The data model graph was generated with the django-extensions graph_models command:

$ fab django "graph_models -X TimeStampedModel,PolymorphicModel -o models.png agents core events utils"

Conceptual model frameworks:

  • BIBFRAME to model objects and relationships for bibliographic resources (the instances for paratexts are resources labelled as paratexts and part_of other resources)

  • BIBFRAME uses FOAF for its Agent class to model relationships between agents, persons, organisations and other objects.

Controlled terms

The vocabularies, data points and taxonomies, used by Radical Translations data model:

  • FAST used for genres (subjects): this is part of the Library of Congress Linked Open Data resources mapped as FAST topics/forms

  • Additional terms for subjects (with respect to types of publications and genres) use terms from the RBMS controlled vocabularies (in particular the RBMS printing and publishing and RBMS genre vocabularies)

  • Wikidata for the professions (roles) of persons e.g. authors and translators as well as types of organisations e.g. political parties vs publishers; Wikidata terms are also used to express editorial classification e.g. of dates (e.g. inferred), events (typology) and relationships (e.g. uncertain attribution)

  • VIAF to identify some of the agents (persons) who are well known translators/authors

  • ISO code for languages

  • GeoNames for geocoded placenames

  • Extended Date/Time Format (EDTF) Specification to express dates

  • In one case controlled terms are based on project-specific terms; this is the case for ‘classification scheme edition’ for the Resources objects (in particular paratexts) with values partially adapted from Kathryn Batchelor, Translation and Paratexts (Roudledge 2018); Amy Nottingham-Martin,”Thresholds of Transmedia Storytelling” in Examining Paratextual Theory and Its Applications in Digital Culture, ed. Nadine Desrochers and Daniel Apollon, (IGI Global 2014), 287-307.
