xDX Application Profile

Note

This application profile is under construction and may not fully reflect the current dataset. The pattern examples and Turtle data samples are subject to change.

Purpose

The purpose of this application profile is to document how xDX Project data is modelled for compatibility with the wider LINCS data model. This document provides patterns used in the mapping of xDX data which correspond to the categories of the main LINCS Application Profiles.

This document introduces classes and properties as used in this specific context (LINCS and the xDX dataset), without providing complete definitions for them. You can find the full definitions in the documentation of CIDOC CRM version 7.3.1 and other reference ontologies and vocabularies.

Ontologies & Vocabularies

This section reports the ontologies, vocabularies, and authority files used in the xDX dataset. The acronyms are used throughout the document to refer to the terms defined in these ontologies. The prefixes are used to compose the URIs in Turtle code throughout the examples found below.

Overview

The xDX dataset reconstitutes the former Design Exchange (DX) collection, documenting the unique history of design in Canada. The dataset describes the design objects along with their creators, producers, and owners.

The image below shows an overview of the entire xDX application profile. Each section of the diagram is described in detail in one of the sections of this document. Click here or on the image for a large-scale, more readable version.

xDX Object

An xDX object is a human-made object designed by one or more designers and produced by a company. The dataset represents basic information about the object, including its material(s), dimensions, and acquisition history. The dataset also describes the object's model, brand, and classification.

xDX objects were originally part of the Design Exchange (DX) collection and are currently held by public institutions including the Royal Ontario Museum, the Canadian Museum of History, the Archives of Ontario, Carleton University, and York University.

Production

xDX objects were produced between 1940 and 2010 by Canadian and international production companies.
