# Reflections on the Intermediate Data Structure (IDS)

## TL;DR

The paper discusses the Intermediate Data Structure (IDS), a flexible format for sharing life course data that uses unfamiliar data models to handle complex life histories.

## Contribution

The paper highlights IDS's novel features like the Entity-Attribute-Value model and embedded metadata, which enable cross-domain data sharing.

## Key findings

- IDS uses the Entity-Attribute-Value model to represent complex life histories.
- Embedded metadata and the Chronicle file enhance IDS's flexibility and expandability.
- IDS has parallels in other scientific fields, suggesting potential for future innovations.

## Abstract

The Intermediate Data Structure (IDS) encourages sharing historical life
course data by storing data in a common format. To encompass the complexity of
life histories, IDS relies on data structures that are unfamiliar to most social
scientists. This article examines four features of IDS that make it flexible and
expandable: the Entity-Attribute-Value model, the relational database model,
embedded metadata, and the Chronicle file. I also consider IDS from the
perspective of current discussions about sharing data across scientific domains.
We can find parallels to IDS in other fields that may lead to future
innovations.
